Ben, you mean to tell me the Audi has no low tire warning lights? My POS Buick has a dummy light for tire pressure. Shame on Audi for that one. Especially in a performance model.
On a side note I went to drive the Bimmer the other day after it was parked for over a week. Jump in, fire it up and I get a warning for low pressure. Check the TPMS menu and ALL 4 tires are low. By looking at them you cant tell. Push the sidewall, nice and firm. Go check them and 2 were only 4 psi low, one was 6 and the other was 12! With low profile performance tires you definitely cant tell. I wouldve never checked and who knows, after a trip or two the same thing might of happened. I, for one, love the technology.
