Incredibile Audi A6, does it comply with FMVSS138?

Are you serious? You're basing the entire safety of the car on the fact that the TPM system doesn't work 100%?? There is a lot more that goes into a car about safety than just that. Better airbag delployment, better designed crumple zones, etc.
What's got you so uptight about the TPM? I mean you are REALLY going at it here. If you compare your car to mine (as I was doing) just the fact that it HAS a TPMS means that it's a lot better at general safety than my car. We agree with you that it should be fixed, but it's not like we can determine what Audi does based on one complaint in the forums here.
Why on earth would you call this a cost reduction? It has nearly nothing to do with cost; it's just a bug in the system that most likely will only cost labor hours to fix - not really a big savings coming from the automaker.
Since you're actually an owner of a 2009 (hopefully), have you personally witnessed this problem, or are you just going off fear that the videos instill? Again, what are you really doing here? The most we can do is agree with you and we do; it's not like Audi reads these forums for complaints - you have to contact them.

Why would you let this issue bother you? They have so many other more important problems. i.e. Crappy rubber seals, Constant blinding CEL's, Honestly side by side with the Cobalt for 100K and no service I'll bet the Chevy won't leak oil from every seal it has.
However at 100K the cobalt will have 4 un-matched cheapo tires on it, at least one will be a different size. That's for sure.
Also Why is Audi being compared to a Cobalt and not a BMW or Benz???? Could it be somebody is trying to steer us toward Chevrolet. (I am a huge Chevy fan by the way, even if my sensor's didn't work on my $50K Suburban) Considering they totally used Audi to redesign the Suburban line maybe that's what this is. If that's what this is all about then while I'm on the subject the Interior of the Corvette looks like crap Should donate it to Ford -Please steal some ideas from the R8 and do an upgrade. I like the exterior of the new Camaro, but never liked the square gages in the original or in the stinray for that matter, Interior looks like plastic. The interior on the Suburban's is right on, I like it, Nice job! I don't care who you stole it from it looks awesome. Oh and please put the dashboard cup holders from the late 90's trucks back in. They were tough and I could put two coffees in there and hang my cell phone on the side!

Well I do have a 2009 a6 and I have checked with my own car that this failure mode is actually repeatable. The problem is that Audi has changed technology approach from the previous version of the A6 and this one by adopting the so-called "indirect" TPMS technology, that evaluates pressure from tyre rotation change and vibration analysis. This brings all the problems that I mentioned before but reduces the cost of the hardware by around 20 dollars (you do not need pressure sensors in your tyres anymore).
The only way to fix this bug is by fitting the sensors back again.

As said before, the test in the video leaves some correct information out.
When pointed out to him that his particular test is not indicative of the system's failure, why the person who performed and uploaded it on YouTube DID acknowledge that actually should be pertaining to an INCORRECT RESET/CALIBRATION?
Translation:
What did the author respond?
"dear Gilbert, you are completely right, this is why I changed the title of the video "
QED...

If you rely solely on the TPMS to warn you that overnight a tire got deflated to the point where is unsafe to drive on it, then maybe you shouldn't have a driving permit... as you present a serious risk to the other motorists.
Edit: By "you", I mean to say every driver in that posture, not YOU in particular.
(I thought a clarification was needed for obvious misinterpretation reasons)

Ce test ne démontre pas que le TPMS de l'Audi ne fonctionne pas. Il démontre le risque grave associé au bouton "reset" de certains TPMS.
La procédure correcte consisterait à gonfler les pneus correctement (pneus froids, manomètre en bon état et étalonné), à faire le "reset", puis à dégonfler de ce que vous voulez, 25%, 40%, à démarrer et mesurer le temps de réaction du TPMS. Au delà de 10 minutes pour 25%, ce sera "no good". Bonne route.

This test doesn't demonstrate that Audi's TPMS system is mulfunctioning. It demonstrates the possible serious risk associated with using the "RESET" button. The correct procedure consists in inflating the tires as recommended (tires should be cold, using a tire gauge that's calibrated and in good working order), and then RESETTING. After that, the tires can be deflated by whatever percentage you desire, 25%, 40%, and start driving the car and measure the TPMS' reaction time (to identify the deflation). Recognition of the deflation beyond 10 minutes for 25% deflation is not good. Have a safe driving.

I disagree on the safety, the new TPMS system is less safe than the old one, I just want to highlight this element to the people of this forum.
Audi had a system, on the old A6, which was foolproof, efficient for single punctures as well as multiple punctures, could display tyre pressure values location and temperatures, warned you if you had a deflation during the night, and extiguished the warning on its own once the pressure was rectified.
On the new Audi A6 the system does not warn you as efficiently for multi tire deflation or puncture, cannot show pressure value anymore, does not alert you if you have a puncture in the night before you drive off, and if for some reason, intentional or not you miscalibrate it, you run the risk of thinking that your tyres are ok, when they are actually unsafly soft
Do you call this a safety improvement?????
I call this a cost reduction exercise to the sole benefit of Audi, it is a pity the vehicle is 10% more expensive than the previous version.....

This is an example of how the government forces useless, expensive devices on manufactures and owners, rather than requiring drivers to directly check their tire air pressure. By it's nature any such device just creates more false warnings or no warnings. It is just another unfunded mandate.

well, this system was mandated after the underinflation issue linked to the firestone affair in 2000 led to the death of more than 100 people (and two dogs). I am not sure, considering the results, that this was a bad idea

I apologize for a mistake...I should have said "this makes the Cobalt looking like the smarter choice", which the LOL was intended for.
Chevy makes some good cars, but the Cobalt (replacing the crappy Cavalier) is not one of them. I wouldn't hit a big auto show to peruse the Cobalt.
(Not important, but I attend every year the Chicago Auto show). I still keep my LOL regarding the Cobalt...
What do you do, jump from Cobalt to Cadillac? LOL
P. S. By the way, I would take any day a Taurus over a Cadillac (given same manufacturing year and condition). And I would certainly take the new Taurus over the CTS wagon.

The new Taurus SHO is pretty sick. I've seen one in person and it's a TANK, definitely one of the largest sedans i've seen in a while, especially from ford. Getting the 3.5L EcoBoost (what kind of name is that?) will net you 365Hp and 350lbs torque with the same mileage as the lesser 3.5L@263hp. I think the 0-60mph time was around 5 seconds. Then again with the options fully loaded it costs around $46K which is the same price as a brand new S4...
