In some 3.0 TDI 272 HP engines, abnormal noises and knocking are reported due to camshaft wear on the exhaust side.
Engine Internal
In some versions of the 3.0 TDI, low oil pressure at low RPM can accelerate wear of timing chains, tensioners, and auxiliary components.
Timing chain
In some V6 TDI engines, injector seals/O-rings become brittle or wear over time, causing oil leaks toward exhaust or manifolds. This can result in burnt oil deposits, smoke, or failures of accessories like alternator/serpentine belt.
Fuel System
Errors related to turbo position (boost position), boost loss, and abnormal noises are reported. These issues may be caused by actuator or vane sticking due to carbon deposits or wear in the variable geometry turbo.
