- Summary
- On certain audi vehicles with a 3.0l tfsi engine manufactured during a specific period, the diagnostic thresholds for the catalytic converters were programmed too tightly in the engine control unit. As a result, the malfunction indicator light (mil) may come on even though the catalytic converters are working properly. If the mil is on, a vehicle will not pass an emissions inspection.
Owners of these vehicles have filed 112 complaints in the electrical category.
