Help Request Posted
2008 Audi A4 Quattro 2.0L MIL Lamp on VIN: WAUDF78E98
P2187: Bank one system too lean at idle. no signal/intermittent. I'm having trouble finding any information for this code. My Snap-on Verus has no information. Alldata has nothing either. Any Audi techs out there have any help. Car seems to run fine. I cleared the code and it hasn't returned yet, but I bet it will soon.
