Hello everyone,

I started this thread because I have a 2010 A6 Quattro Avant and I thought it had the Tire Pressure Monitoring System (TPMS), however, I now notice that all four of my tires are about 15psi low, so now I'm doubting if I have TPMS or if the system is malfunctioning. When I start the car, I never see a TPMS or tire with the "!" symbol and when I press the "check" button on the dashboard, there is no reference to TPMS. I also checked the manual and it says with a footnote "if installed".

???????? When you turn key on, do you get a TPMS lite on dash for a second during bulb check or can you see the lamp during outputs?

I did not notice any dash warning/idiot lights that show the TPMS icon or text, but I will check the next time I start the car.

So I posted my auto-scan (which I will repost below) to see if the car has TPMS but it's broken or if TPMS was never installed. From the reviews there is no mention of TPMS in my autoscan, so it is possible (at least for a Canadian Audi) that TPMS is/was an option for 2010. Here's the auto-scan:

How about call Audi dealer with VIN # or customer advocate at Audi headquarters customer care?

Depend on which system is fitted IF. If you have the direct system you will have different tyre pressure sensors in the wheel noted by a threaded tyre valve.

Volkswagen Tyre Pressure Monitoring System (TPMS)

It appear that Canada have the obligatory TMPS the same a USA. http://www.tc.gc.ca/eng/motorvehiclesafety/roadsafety-1158.htm

Even if your tyres are all 15psi the indirect system won't be alerted as the rotational speed will all be the same.

I have 8 error codes for Tyre Pressure Monitoring System (TPMS):

VAG 03159
VAG 8392961, EOBD II C104C
VAG 8397058, EOBD II C1050
VAG 8397314, EOBD II C1051
VAG 8397570, EOBD II C1052
VAG 8397826, EOBD II C1053
VAG 8400898, EOBD II C1054
VAG 8400901, 8400904, EOBD II C1056

I'm not so sure this is true for all systems. Case in point, installed snow tires with 17" rims on my 2015 GTI. About 12miles later, on second ignition key cycle, TPMS light came on. Huh, I double checked and all were set to the same pressure when installed. Drove home a little nervously, then read the owners manual.

Owners manual specifically states that the indirect TPMS system must be reset when changing wheels and tires. Did that and all is good. So at least on this car, North American (USA) model, the indirect system is more sophisticated that just rotational speed discrepancies.

Correct, the FMVSS that apply are a performance-based standard and they demand that the system be able to identify a situation where all four tires are equally (but grossly) under-inflated. Exactly how an indirect system accomplishes this, I do not know, but the car manufacturers have to prove that it can in order to get these systems certified.

Could it be that there is a speed sensor on the transmission and this reading combined with wheel speed sensors and engine rpm for a given speed /gear ratio triggers it?

Indirect TPMS can't detect gross underinflation, which I believe is why markets with that requirement or another performance based test will fit direct for that market. Audi in Europe have used both systems, but the last I can think of that had direct were the D3 A8. Cheaper models were generally first to move to indirect (which is what BMW have also used in Europe with run on flat tyres for many years) as no sensor costs.

Indirect is basically useless except where 1 tyre gets a puncture.

That's not correct. The US performance based standard requires a TPMS system to detect when all four tires are grossly (but equally) under-inflated, and there are lots of cars sold here now that use indirect systems. I'm not sure exactly how they accomplish this, but they do.
