I just sent the following to Audi Canada, if anyone has suggestions of where I might get a rapid response I would welcome it:
To whom it may concern,
In early June of this year my wife gave birth to identical twin boys. Dues to the physical size of modern CSA approved car seats our previous car, a VW Jetta was too small for the two car seats so in late June I purchased (financed) a Certified Pre-owned Audi Q7 (VIN: WA1Cxxxxxxxxxxxx).
By in large I am satisfied with my purchase, it is one of the few vehicles large enough not only for my wife and I, our two children, their car seats and a stroller but it even has room for a few groceries after all of the above. However, the truck does have one very serious deficiency, specifically, the automatic door locking after 60 seconds of inactivity, I call this a defect because this “feature” could have killed my children on the afternoon of Friday September 21.
On that Friday afternoon, my wife had loaded the car seats and babies, into the car and realized she dropped her car keys on the ground. She shut the car door, and walked over to the keys, only then realizing she had in fact dropped her house keys (the garage door key fob looks like an Audi car key and was on her house keys), the car keys were in the car. By the time she returned to the car, the doors were locked, with, as I already noted, the car keys inside the vehicle.
Ultimately, and luckily for my wife, as I was at work at the other end of town, a tow trucker driver was near-by, he spent about twenty minutes trying to jimmy the door lock, as both my sons and my wife became more hysterical, finally, he smashed the passenger side front window.
Frankly I don’t care about the damage to my vehicle, it’s a machine, it can be repaired or replaced, my children are, my children, there is no point of comparison. When I found out what happened naturally I got to my wife as quickly as possible, luckily the boys are fine and the car is at a shop getting new windows and repairs to the door.
As one might expect I contacted my dealer (Crosby in Kitchener ON) they told me they had never heard of this happening before, which is very strange as the tow truck driver told my wife he sees this all the time. The service department at Crosby told me there is no way to disable the auto locking feature on Audi’s, this is apparently an anti theft measure, as there are a limited number of frequencies for key fobs the concern is two similar key fobs in the same car park could result in one car being left unlocked.
As a computer network engineer by training and network security professional by trade I appreciate the need for strong security; however, I find this situation totally unacceptable. In less than three months of owning the Q7 a reasonable set of circumstances conspired to leave my infant sons locked in the vehicle until someone smashed a window, scattering glass all over my children.
I believe that if I pursued this matter in the civil courts I could ultimately, after some great cost, find financial restitution; however, as an engineer I do not see any sort of civil action as an effective resolution of the fundamental problem, namely the car locks itself with the keys inside.
As an engineer I would therefore request the following changes be made to the existing auto lock feature, or if it cannot be made with a firmware update then future models have the following changes:
1. If the car is unlocked with a key inserted in the door, the car stays unlocked until locked from a fob or by the key being reinserted. (It would be an easy habit to get into, not to use the fob to unlock the door, up until the mid 1990s that is how all cars worked.)
2. Give owners the ability, either through a dealer provided configuration change, or a owner performed change, to alter the auto lock timer, in short allow me to decide if I want more than one minute to get in the car after I press the button on the fob.
3. Use CHAP (Challenge Handshake Authentication Protocol) with the key fob serial, VIN and a date/time stamp to properly certify that the key fob is truly the fob intended to open the car door. (This is a somewhat technical solution but I was able to design, in my mind, a very secure authentication exchange between a key fob with a very limited processor/battery and the car that would be virtually undefeatable yet ensure total uniqueness of the key fob without switching radio frequencies or otherwise stretching the limits of existing technology.)
As I noted, I don’t want to treat this as some cause for a civil case, frankly I think Audi’s are generally pretty well made machines, and civil cases are for people not interested in actually solving problems. My wife and I both enjoy the Q7 and are, or were until Friday, considering replacing our CPO model with a brand new Q7. I would be more than happy to speak in greater depth to my three recommendations. I look forward to your prompt response.

On Internal Combustion and Other Things
I've been thinking a lot lately about the BCC, I've no idea why, well I've gone for my first few serious (i.e. 100km+ bike rides) since the boys were born. Anyway I was talking to Dawn about the BCC, she only rode with them once but was not impressed. One guy hit on her, another, upon learning that there was to be no networking opportunities with Dawn couldn't be bothered to talk with her, I didn't learn any of this until just a few weeks ago. I find it ironic, though, the guy that hit on Dawn, well Dawn thought he was ugly. Anyway Dawn was already living with me when this happened and now she's my wife and mother of my children.
If I can just address the guy who was hitting on Dawn. Really, hitting on another guy's girlfriend is a really classy act E.M. (I'll put his initials), but hey you've never been particularly pleasant to me which pretty much explains why I detest you. The hitting on the woman I would propose to less than two months later, that was just... well frankly completely unsurprising. That seemed like the sort of thing you would do.
I guess it's a shame though, there are some great guys in that club, Thi Ng, Ian Willcox, but truth is I'm okay with riding alone, riding is already a pretty solitary activity to begin with and with infant sons I find it impossible to hit the road on any sort of schedule. (I feel guilty seeing Dawn scrambling about organizing bottles and changing diapers so I generally help out until at least one of the boys has settled.)
At least I've been able to pack in a few rides lately, as I documented earlier, slowly I'm rebuilding my base. It's remarkable how much things have fallen apart for me (from a physical abilities perspective) since the birth of the two little ones. Though of all the reasons to loose a base, well frankly twins really are a blessing, they don't have colic (knock wood or something!) they are both gaining both height and weight with a remarkable speed. They are the cutest little things... big things, and yes they've turned my life inside out and upside down and I wouldn't trade it for anything!
I remember in 2010, I was riding all the time, I'd have to look at my calendar but I suspect in August and September I was averaging about 500~1000km/week. Now I'm not doing that in a month, but I'm not lonely and the T.V. is principally a source for background noise. (Though I still try to watch the Daily Show, when John Stewart covered the RNC I couldn't stop laughing... though perhaps I should be crying?)
Anyway I was reading some of my anti-SUV posts, I feel rather ashamed of my truck, but then I remember the grief I had trying to make something more modest work. The fact is, if you've got a family with twins you're going to need a really big machine, either a mini-van or an SUV and I just cannot bring myself to buy a mini-van.
Ironic really, I remember when my brother and I were young we didn't have car seats, back seats only had two point restraint, lap belts, and there were no airbags. Now by law children under a certain size or age must sit in booster seats or full on car seats and there are regulations for car seats that make the damn things so big you need a huge vehicle if you have multiple children. Maybe that's why SUVs became so popular?
That wouldn't explain the vegan I know who bought himself a Tiguan, he's got no children. But here's a random thought on veganism, suppose Dawn or I, or both of us were vegans (praise be Bovine god of steaks were not!), but anyway suppose there was a vegan in the family would the boys be allowed to have breast milk? What about women who are unable to produce breast milk, say for medical reasons? Would they be allowed to give their children formula which is basically vitamin and mineral fortified cows milk? What if their children had say, an iron deficiency, sure they can give their kids spinach but lets face it, you need to boost your iron levels have a steak! (Well liver actually is the most concentrated iron delivery food, but it tastes so bad and steak is only marginally lower down the iron content table, go indulge, have a double porterhouse at Harbour 60, its a medical necessity!)
I've thought about the vegan a few times, you see when he rationalized his purchase of the Tiguan he used something to the effect of "that 2L Turbo engine is very efficient". No it's not, I had one, well back then it was a 1.8L Turbo in my Audi A4 years ago. Anyway I guess VW bored out the cylinders a little, but the point is, that thing was a gas guzzler for a small sedan it had appalling fuel economy. (A full seven seater Toyota RAV-4 had better fuel numbers than the five seater A4.) But I just want to point out how a remark like "2L Turbo is very efficient" reflects a lack of understanding of basic auto engine design in particular the fundamentals of what a Turbocharger is and does. Okay, I know someone's bound to ask, so here's a link to turbo's or if you know me, just ask and I can give a more non-technical explanation as to why the remark "a 2L Turbo is very efficient" is such an idiotic thing to say.
And to think I'm contemplating trading up my 2009 Q7 for a brand new supercharged 2013 Q7, (I'm fed up with being cut off in the city), I know going from a 3.6L naturally aspirated to a 3.0L Super is going to be ugly at the pumps but I can live with that, the thing that's eating me right now is how unresponsive the truck gets when I mash my foot into the firewall. Yes, I've thought about all the torque in diesel, but I'm being cut off at speed, not from stop lights. Still I wonder what ole' Carroll Shelby "there's no replacement for displacement" would say about our modern super and turbo charged engines.
I should've been a mechanical engineer sure I don't really approve of internal combustion engines (for environmental reasons) but the physics of them sure are interesting. (Yes I know it's all 19'th century technology, but hey, there were improvements made, back in the 20's, the 1920s!) Anyway can't I be interested in painfully obsolete technology?

On Being Out of Shape
Dawn has four brothers, two are older, two are younger. All but the very youngest are married with children (or a child in the case of the second youngest). Anyway Dawn's second youngest brother calls up about a week ago and asks if we could look after his daughter for Friday night and Saturday morning. Apparently before I got into Dawn's life she enjoyed the roll of being the family baby sitter, though I have to wonder how twins have changed that job title.
Now Dawn's brother lives in Shelburne which is about an hour's driving distance outside of the city and as it would turn out Dawn was able to enlist the assistance of her mother, so that it was three on three (it's not like we are going to hire a sitter to look after the boys while we run off to Shelburne to look after one girl!) Anyway I hit on the idea of biking from our short term rental, (oh did I mention we moved to a rental while we sell our smallish home and once sold look for a largish home - twins for you!) to the house in Shelburne.
Here is the route I took,
Because Dawn's mother, my mother-in-law, would be able to look after the baby we were more or less not required, still it might be nice to get out of the city for the day. So Dawn asked if I wanted to go Friday or Saturday. As I was able to get off work Friday it came down to a simple decision for me, ride away from the city during the morning rush hour, or on Saturday when the yahoo's would be out. I thought Friday made more sense.
It was probably a foolish move, it turns out there's an awful lot of cars on country roads on a Friday, one road in particular, Charleston Side Road, near Erin was horribly busy, and every time a 54 foot tractor trailer drove past, and more than one drove by, I really thought, I ought to up my life insurance. Anyway I think I've got a better route for next time, and here it is:
Sadly on this ride I realised how much things have fallen apart for me since the boys were born. (I guess I expected it, but still, expectation versus actual discovery of fact, it was upsetting). The ride was 137km, which is a nice distance for me, nothing really far, heck last summer I rode up to Lake Simcoe by myself a bunch of times and that was 180km, I even did a Forks of the Credit ride alone and that was just over 200km. Well this time I started a lot closer to the Forks and got there with 95km on me and I was tired, the knees hurt, the legs hurt, my rear end hurt. I stopped for a fluids break and resumed about 20 or 30 minutes later, hurting. It was a shame really, quiet country roads, lovely rollers, farm land, nice weather and I hurt too much to notice pretty much anything at all.
I'm not going to give the statistics, they are too upsetting, instead I'm going to go back to clean my sweet ride and hope that I can mount the saddle again soon, I've got to get back into shape.

On The Boys and Car Problems
So since my last post both boys have gone into a little growth spurt. These things happen, but its not fun. I don't recall my own growth spurts, from my early teens, being a big deal - I'd go to summer camp and when I came home Adam (my brother) or my parents my comment on how I looked taller, and of course clothing was smaller, but I didn't feel anything. I ate like a pig, but I've always eaten like a pig.
Anyway for Josh and Zach a growth spurt means that they eat more, normally Zach eats about 50~80mL every three hours and Josh has about 80~120mL about as often, but during a growth spurt the two trouble makers just don't stop. And then they are cranky, they cry and scream, Dawn says that the growing is painful, well yes formula is expensive and I stockpiled diapers before they were born and now they are outgrowing the diapers faster than the boys go through the stockpile - does anyone need a box of 160 Pampers swaddles size 1? (I'll sell an unopened box for $26 - what I paid for it.) But when Dawn says growing is painful apparently she means the boys are in some pain, well yes when they scream it's a pain in the ears. I've been changing diapers when they get started and holy smokes I can feel the screaming, it vibrates my entire body!
In other news, the car. Right my 3000kg piece of hypocrisy. Well I should stop on the self flagellation, it was a very necessary evil. (If Dawn and I had bought the thing before we knew about the car seats, or the twins, then it would be different, but really is the thing that bad, given that we do need such a large vehicle?) Anyway as I noted in my previous post I bought a used Audi Q7 from a dealer, a 'Certified Pre-Owned', it was financed too, it's not as if I have that kind of money just lying around. Anyway at purchase it had just less than 50,000km on it and was a 2009 model year, bought (well leased) in mid December 2008. I've got to wonder about that, hardly three months after Lehman went bankrupt someone wanders into an Audi dealership and says, 'I want the biggest truck you guys sell!, but since the world's about to roll into a depression the likes we haven't seen since '29 I'll just get the 3.6L VR-6 not the 4.2L V-8.'
Okay so I've got this new used truck and as part of the pre-owned certification it gets new tires, new brake pads and rotors, heck the dealer even put new calipers on them brakes. Its got a new rear-bumper, previous owner did a number on that and a bunch of other new things, like an iPod cable. But one thing that's not new, the engine oil. I've owned the thing for just shy of a month, maybe driven it 1000km and I drive out to a friend who's a big auto enthusiast. Well he checks out the engine bay, which I had hardly ever glanced at, he pulls out the dipstick and sure enough the oil is black, like 5000~10,000 kms, not 1000kms of driving.
Anyway since the truck has a nice high ground clearance I figure I'll do the oil change myself, it's not like I'm not familiar with the theory of doing a lube job, I've just never felt comfortable going under a low slung car. Anyway I get some car ramps and an oil drain pan from the local Canadian Tire, the oil, filter and pan plug from my local dealer - not the same idiots I bought the car from. Get out my socket set and set to work.
First as I noted in my last post I have a 3.6L VR-6, what that means is the engine block is smaller than a typical V-6, this VR-6 engine was originally designed for the Passat which has a smaller engine bay. Anyway given that the other engine available in the 2009 Q7 was a 4.2L V-8 you might expect that Audi would move things around to make engine maintenance a little easier... Ha!
So I get under the car and have to remove about a ten bolts in the skid plate, turns out there were supposed to be 14 bolts but I am guessing someone at some maintenance interval at the dealership that sold me the truck (they did all the maintenance for the previous owner, they told me) got lazy, then I go hunting. Finding the drain plug for the oil pan was not too hard, it was on the side near the bottom of the pan. Question, why not put it on the bottom of the pan? Besides being easier to get at the oil would go directly down, no matter how much oil had already drained. When the plug is on the side at first the oil lands a good half meter from the plug but as the oil drains it falls closer and closer to the plug, thus unless you remain under the car and watch things you end up with oil on the ground. Oh and the drain plug, its right up near the axle. I had to buy a 19mm wrench because my socket was too big to fit in the narrow space and none of my wrench sets go past about 15mm.
Anyway I get the oil drained and look for the filter, now there must be some law that German cars no longer use traditional filters in the disposable metal housing. Instead the filter is just some paper and a rubber seal. The filter housing is built into the car, you remove the housing, remove the filter, replace the filter, reinstall the housing. Except, removing the housing requires a 36mm socket, which as one might imagine, I don't have. My socket set goes up to 24mm. I also bought a 1 inch socket for my cassette lock ring tool. So I walk to Canadian Tire and look for a 36mm socket, no such luck. I put in a new drain plug, pour in fresh oil (hey better than nothing.) And drive to an auto parts store, I buy a 36mm and a 32mm (just in case) socket. I have yet to do the filter and when I do, I guess I better replace the oil, again! Oh but that filter, it's hidden away behind some cable, why on earth couldn't it be in easy reach it's not as if oil and filter changes are about the most common auto maintenance besides filling the gas tank and tires.
Anyway although I've only driven about 10km with the fresh oil, and a stale filter, I have to say, the truck is a lot more energetic when I hit the gas. Maybe it's in my head, but it feels like I just packed another ten or twenty percent more power. Really if the dealer had any brains, especially since I scheduled the test drive about four hours before I got there, they'd have scrambled to do the oil change in that four hour interval. Heck without a hydraulic lift I was able to do everything from removing the skid plate, including walk to Canadian Tire to buy a 19mm wrench right to curse at the frigging oil filter housing and replace the skid plate in about two hours. I'd like to think the guys at the Audi dealership can do an oil change a little faster than that!
Arrrgh, what am I going to do when it's time to do a coolant flush? One things for sure, I am not taking a car to dealer for routine maintenance, ever.
Anyway for Josh and Zach a growth spurt means that they eat more, normally Zach eats about 50~80mL every three hours and Josh has about 80~120mL about as often, but during a growth spurt the two trouble makers just don't stop. And then they are cranky, they cry and scream, Dawn says that the growing is painful, well yes formula is expensive and I stockpiled diapers before they were born and now they are outgrowing the diapers faster than the boys go through the stockpile - does anyone need a box of 160 Pampers swaddles size 1?

When the plug is on the side at first the oil lands a good half meter from the plug but as the oil drains it falls closer and closer to the plug, thus unless you remain under the car and watch things you end up with oil on the ground. Oh and the drain plug, its right up near the axle. I had to buy a 19mm wrench because my socket was too big to fit in the narrow space and none of my wrench sets go past about 15mm.
Anyway I get the oil drained and look for the filter, now there must be some law that German cars no longer use traditional filters in the disposable metal housing. Instead the filter is just some paper and a rubber seal. The filter housing is built into the car, you remove the housing, remove the filter, replace the filter, reinstall the housing. Except, removing the housing requires a 36mm socket, which as one might imagine, I don't have. My socket set goes up to 24mm. I also bought a 1 inch socket for my cassette lock ring tool. So I walk to Canadian Tire and look for a 36mm socket, no such luck. I put in a new drain plug, pour in fresh oil (hey better than nothing.) And drive to an auto parts store, I buy a 36mm and a 32mm (just in case) socket. I have yet to do the filter and when I do, I guess I better replace the oil, again! Oh but that filter, it's hidden away behind some cable, why on earth couldn't it be in easy reach it's not as if oil and filter changes are about the most common auto maintenance besides filling the gas tank and tires.
Anyway although I've only driven about 10km with the fresh oil, and a stale filter, I have to say, the truck is a lot more energetic when I hit the gas. Maybe it's in my head, but it feels like I just packed another ten or twenty percent more power. Really if the dealer had any brains, especially since I scheduled the test drive about four hours before I got there, they'd have scrambled to do the oil change in that four hour interval. Heck without a hydraulic lift I was able to do everything from removing the skid plate, including walk to Canadian Tire to buy a 19mm wrench right to curse at the frigging oil filter housing and replace the skid plate in about two hours. I'd like to think the guys at the Audi dealership can do an oil change a little faster than that!
Arrrgh, what am I going to do when it's time to do a coolant flush? One things for sure, I am not taking a car to dealer for routine maintenance, ever.

On Updates
So Dawn and I do the nights in shifts, I take the first shift, from around 10 or 11pm until around 2 or 3 am, at that point. I crash and burn out on the bed and Dawn takes over looking after the little ones. Its exhausting in a way I`ve never been before. And when they start up, their lungs sure work plenty good.
Dawn and I gave the cats up for adoption, we had no choice, Zach was having breathing problems and with the upcoming move... well we have to move the house is too small. Two boys and since I work from home so often now, we need a four bedroom, or I suppose a 3+1, but a guest bedroom might be nice. The car was too small as well, long story there but I am now a hypocrite (at least I don`t actually drive that much, and when I do, the thing is chalk full of stuff, strollers, car seats, people). But lets be honest I said (or implied anyway) that nobody ever should buy an SUV, and in my defence I did try to find a four door hatchback, a station wagon, except as it turns out there almost none in North America, nowadays people buy SUVs, groan. (The few large enough station wagons I did find that weren't total rust buckets were still smaller then what we bought.) Anyway I`m going to make a big exemption in my nobody should buy an SUV, parents of two or more children are summarily allowed large vehicles. Although minivans do make more sense, if you can tolerate the assult on your vanity. (One really cool feature that no minivan or station wagon can do, we can use the trunk as a change table/chair for sitting whilst feeding - yes we've had to do that, twice in under a month. Toronto's "expressways" do a double duty for parking lots, and when the boys need to feed, or get a change, we hardly have time to find a properly legal parking spot, let alone a McDonalds or some other establishment with clean washrooms and change tables.)
Does this justify my driving an SUV? Probably not, but at least I won't make any wild claim about fuel efficiency. It's a 2009 Audi Q7, with a naturally aspirated 3.6L VR-6 (VR is a V engine with the angle between the pistons reduced from the usual 90 to 75 degrees down to about 15 to 10 degrees... Frankly it's silly, the engine bay could easily handle a proper V6, the other engine in that model year was a regular V8, 4.2L. I think VW/Audi couldn't be bothered to design a new block so they took an off the shelf block that they also use in the Golf or something.) Anyway it's not at all efficient with the gasoline (well I don't think VW knows how to make a fuel efficient engine, the 4.2L V8 is also used on the "sporty" S4, it has something like 320bhp -considering the size of the block that's pretty feeble- yet can hardly crank out 500km on a 100L tank of highway driving), oh and since it's German the owners manual says I can use 87 octane gasoline, but they strongly encourage 91 octane or above only. About two weeks after I got the thing I did some number crunching, in the old four door diesel Jetta I paid about $0.05/km for fuel, in this monster I pay $0.18/km. Thank goodness I don't need to drive 40km one way to work each day any longer, I take a train, it's great, 11 minutes from the station (that is a 7 minute walk from my front door) to the station by work. The only driving I do anymore is take the boys out to see family or friends and buy groceries... sometimes I walk to the supermarket, so the fuel use isn't actually all that bad.
I guess it's better if I can go from driving lots in a smaller car, to not driving much but when I do, using a huge thing. Oh and before anyone asks, yes I tried using a mid-sized SUV, my mother-in-law let us use her Mazda CX-7, room for the boys, stroller and wife, but no groceries at all. In fact one Audi dealer tried to get us into a Q5, and once we put the stroller in I was pleased, until the dealer reminded me we needed to get groceries too. Eating really throws a wrench into some plans.
Other than that, I've been living at home almost to the point of being stuck here, I knew this would happen, I just cannot wait until the boys can last a little longer without adult intervention, but I guess that's next year. I've done a total of 3 short rides since they were born.
Oh and there are more pictures, one of Dawn's cousin's is a professional photographer, she'd never done twins before so she was very pleased with our situation and did these shots for free.

On Zachary Alexander and Joshua Dyson
Yes I have not published anything lately, I have an excuse, one word really, five letters, starts with T, ready? TWINS. So here are the pictures.
The pictures above were taken the day Josh and Zach were born.
These pictures were taken one day after birth.
These pictures were taken two to five days after the boys were born.
At birth, Josh weighed 2350g and Zach was 1940g. Although Zach was breach, because Josh (who was vertex) came out first at 0150 on Thursday June 7 Zach was able to slide right out, feet first at 0157, as a result these boys were among the 15% of twins to be delivered vaginally. Due to Zach's small size he was put in the NICU for the first day, then transferred to the Level 2 Nursery for the following four days. Josh who went straight to the Mother and Baby unit with his parents was discharged on Sunday June 10 and the three of us then spent the next two days in the hospital waiting for Zachy to be discharged, yesterday Tuesday June 12. Both boys have undergone hearing and vision tests and so far appear quite normal expect perhaps for their slight size, which is also normal given that they are twins.
On a related note, their gestation was 36 weeks six days, the birth was induced and mommy's water had to be broken at the hospital (which given the kind of volumes involved, daddy was very happy he did not have to clean up!) Oh and I should also note, for singletons, gestation is normally 40 weeks, but for each additional child subtract 4 weeks, so twins are normally 36 weeks and triplets are 32 weeks. In short, besides many a sleepless night, trying to coax little Zachy or Joshy to settle down and let mommy and daddy get some rest, everything is fine, if suddenly a lot busier than just a few days ago!
