TPMS mystery
#11
The B8 A4 does not have TPMS sensors per se -- it uses ABS and other existing onboard systems as indirect ways of inferring tire pressure.
But yeah, the "downside" of indirect TPMS is that it basically knows a "normal" and an "abnormal" state, and abnormal can be anything a 2PSI imbalance to a flat tire. The Audi system is not as bad as the 328i's system in my experience in terms of its trigger-happiness, but what you're describing sounds fairly normal.

I'm wondering if the batteries that are in the TPMS' have a low charge and like all batteries when they get cold they loose some of their charge therefore giving these false readings. Looking at the information provided on this link below.
