Vehicles using AEJ engine list:

Engine AEJ in the Audi A8 2.8 V6 30V quattro (1995–1996) commonly faces issues like oil leaks, timing chain wear, and ignition coil failures. Diagnosis involves checking for oil spots under the car, listening for rattling noises indicating timing chain stretch, and scanning for misfire codes. Prevent oil leaks by regularly inspecting and replacing valve cover gaskets and seals. Timing chain tensioners should be checked and replaced proactively around 150,000 km to avoid catastrophic engine damage. Ignition coils can be tested with a multimeter and replaced if faulty to prevent misfires. Regular oil changes with quality synthetic oil help prolong engine life and reduce wear.
