Check Engine Light-- new owner
I just bought a 2000 S4 with Alcantar interior. The car is awesome! However, the check engine light comes on. I went to my local shop and the diagnostics reported these problems; P1171- throttle angle sensor impusible; P1137 Bank 1 too rich; P1139 Bank 2 too rich. I heard the it is not uncommon for the check engine light to come in S4's.
Please Advise.
Thanks.

Sounds like you may need a new MAF, perhaps.
Try searching the archives for those DTC's. I had to replace my MAF sensor when I had both banks reading rich. Otherwise it means BOTH O2 sensors are shot...which is unlikely.
Is the car stock or what? Different downpipes can cause these types of codes.
