Engine complaints dominate what 2011 Audi A8 owners report, with coolant-related issues appearing most often. Multiple owners describe coolant loss that isn't visibly pooling beneath the car, triggering low-coolant warnings and, in some cases, overheating and smoke. At least one owner reports coolant leaking onto or into the engine control module, which adds an electrical dimension to what starts as a fluid problem. Separately, a timing chain and camshaft failure is reported at relatively low mileage, with the check engine light as the first sign. Suspension shows up as the second-named system by volume, though the complaints there are thin. One isolated report describes rust and corrosion on body or frame components. The coolant loss pattern, fluid disappearing without an obvious external leak, is the thread that runs through the bulk of these engine complaints.
