Listed from most frequently reported, each with its source.
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 worn over time, causing oil leaks toward the exhaust or manifolds. This can result in burnt oil deposits, smoke, or failures of accessories like the 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 the actuator or vanes in the variable geometry turbo becoming stuck due to carbon deposits or wear.
