Hey everyone-I'm new to this forum and a new 2000 Audi S4 owner. I am having 2 codes come up: P1137 and P1139 and I'm looking for guidance on where to start looking for the problem. Any ideas? My name is Mike and any help would be appreciated!
I am also looking for an upgrade in suspension, so if anyone has anything available, I'm ready.
Thanks! Mike
