| 2009 Audi A4 2.0L MIL Lamp on VIN: WAUJF78K29 P2188: System too rich off idle sporadic. This one came in Saturday at 4 pm. I have not done much to it. Vehicle came in with MIL on with no drivability problems. The engine runs really good otherwise. Don't find any air leaks under the hood. Any help is appreciated. |
