For those of y'all with 2008 modelsand run a set of winter wheels and tires, and another set for the summer, how do you deal with the TPMS thing every time you change the wheels?
[ul][*]Ignore the light during the winter[*]Buy a second set of sensors (how do you train the car to a second set?)[*]Have the sensors changed between rims twice per year[/ul]
FWIW, my preference would beto buy a second set of sensors for the winter wheels (assuming retraining the car is possible). Thoughts?

 

All you should have to do is use the dash button to "re-learn" the ideal tire pressure whenever you swap wheels. The A3's TPMS is not a 'smart' system (with a sensor in each wheel), instead it uses the (ABS) wheel speed sensors to tell when a wheel is out of balance.

 

I've heard conflicting reports about the U.S. version of the A3's TPMS system, some say there are sensors (including TireRackhttp://www.tirerack.com/wheels/TPMSS...ModClar=S-Line ), some say the A3 uses the ABS methodology. Furthermore, I've heard that the pre-2008 TPMS models used the ABS version of the truth, however, starting with this model year, ALL A3s use a sensor.

That said, your point about hitting the "re-learn" button makes a lot of sense. [sm=icon_cheers.gif]

 

My A3 2008 US has beru sensors in the wheels.
Dealer wants 80 $ per each of them.
I ended up buying the winter set from Tirerack with sensors included . They ask 55$ per sensor but do not sell them separately.
After installing the new set the tpms light came on. I just pushed the set button for few seconds and went off.
Tirerack gave me great service and price!

 

Perfect! Thank you very much, by confirming the "reset" information in BAMF's post, you gave me the exact information I was looking for. [sm=icon_cheers.gif]

 

Ah, good to know! I didn't realize that Audi changed the setup.
