| 2007 Audi A8 Quattro L 4.2L MIL Lamp on VIN: WAUMV44E57 P2179: Bank 2 too lean off idle. Looking for any additional help here guys. I have high crankcase vent vacuum (18+ inches, measured at the oil fill cap) and I have already replaced the crankcase vent valve. Smoke tested the engine but no leaks found. Maybe a clogged vent tube or orifice? Also... |
