1997 Audi A4 Quattro Q&A
1997 Audi A4 Quattro Question: how resolve low response ?
0441 indicates the evap system has an incorrect purge flow. Though bothersome, it won't give you drivability problems. However, the 1136 indicates too lean condition while the 1476 indicates a MAF problem. Anytime I see this combo of codes come into the shop, I immediately check for vacuum leaks, especially in the rubber air tubes from the filter box to the throttle body. Make sure they are solid all the way along its length and all the way around, and also that they are seated right on their fittings and the clamps are tight. - techpaddle
