Quick question to 2010 and newer Audi owners:

I have an 09 Prestige A4. While driving this past weekend my TPMS monitor went off. It freaked me out and I immediately pulled over in a parking lot to inspect all my tires. Luckily it was just a false warning and I reset the TPMS. I guess one of my tires lost a few PSI that I couldn't notice and trip the TPMS alarm. My question to 2010 and newer model owners is has the TPMS been updated any? Does it tell PSI of each tire or which tire is low when the alarm goes off? Mine just gives the low tire icon on the dash and you have to guess which tire is setting it off. I'll probably check all tires later with a tire gauge.

Thanks for reading.

No my 2011 is the same as yours, just says which tyre has changed .
But doesnt say pressure or much else.

Mine went off the other day, had a nail in the middle of the tyre and dropped 12psi...

RX, no, 2010 and newer cars utilize a sensor-less system. The ABS computer is looking for a change in rotational velocity, etc.

The older (sensor-based) system is somewhat more accurate compared to the newest system. However, the newer system is far simpler and is not a hassle for those doing seaonal tire changeovers.

• Rubber valve stem = sensor-less design
• metal valve stem = in-wheel sensor design

(This is for USA spec cars. TPMS became mandatory in 2008MY on all cars sold in USA. I think Audi has had a system on USA cars since 2005. I don't know about ROW cars. I suspect the Canadians have it, perhaps as an extra cost option.)

Now I'm confused......my 2011 has metal valve stems. So which is it?

My 2011 A4 car has black, rubber valve stems. Can you double-check?

My 2009 has rubber....?????

My 2011 Audi A4 sedan with rubber valve stems from the factory:

Are y'all in Canada? That could be a variance from USA-spec cars. Don't you have TPMS?

I am in Canada and my 2009 did not have TPMS, but it had the proper ABS module, so I took the instruction from DavidB8 WEB site and went to a local garage where they had VAG COM and had them enable the indirect TPMS !

They charged me $35.00 and programmed the remote windows and sunroof opening/closing at the same time.

Works great, but you have to loose about 25% pressure for the system to detect it. It tells you what wheel.

Ahh, that's right. I've heard of others re-coding and enabling an indirect TPMS system. I think it only works on much newer cars.

Was TPMS strictly an option in Canada?
