Known issues and risks
Listed from most frequently reported, each with its source.
Dual-mass flywheel and clutch prone to failure
Often reported
The dual-mass flywheel and clutch assembly are recurring faults on many A4/A5 with the 2.0 TDI; symptoms include noise, judder during takeoff/driving, stiff clutch pedal, difficult gear changes, and premature flywheel wear. Repairs are expensive.
Clutch
Intake manifold flaps (swirl) sticking
Often reported
On some 2.0 TDI engines, intake manifold flaps or actuators can stick or break, leading to vacuum loss, instability under load, and excessive turbo boost issues.
Engine Bay
Clogged DPF (FAP) and incomplete regenerations
Often reported
The 2.0 TDI engines in the A5 can suffer from a clogged diesel particulate filter (DPF/FAP), especially with city or short-distance driving. Symptoms include power loss and forced regeneration warnings.
Exhaust Emissions
Common Rail injectors faulty
Often reported
Injector faults (electrical issues or seal leaks) cause uneven injection, smoke at idle, power loss, and sometimes the check engine light.
Fuel System
Boost pressure loss (underboost) and faulty turbo
Often reported
The 2.0 TDI 170 HP version frequently experiences boost pressure loss (P0299 or similar codes), leading to power drop or limp mode. Reported causes include turbo actuator failure (diaphragm/wastegate) and turbo cartridge bearing breakage.
When buying a 2010 model 2.0 TDI, check service history, test drive, and look for engine/transmission warnings. Most commonly reported issues: dual-mass flywheel and clutch prone to failure; intake manifold flaps (swirl) sticking; clogged DPF (FAP) and incomplete regenerations.
