Brand-wide Audi Problem Patterns
EA888 (2.0 TFSI): High oil consumption (Gen 2) and timing-chain tensioner failure on pre-2012 cars.
S tronic (DSG): Mechatronic unit failure and clutch-pack wear are the primary drivetrain risks.
MQB/MLB Cooling: Water pump and thermostat housing leaks (plastic warping) affect almost the entire modern range.
LED Lighting: Premature failure of DRL and indicator strips in headlight units, particularly on B9-generation cars.
