Common causes of failure and fitting advice for the 2.0 TDI 170

On this type of turbocharged diesel engine, turbo service life depends heavily on the quality and frequency of engine oil changes, the condition of the air filter, and the integrity of the intercooler. Driving too hard after a cold start, or switching the engine off immediately after sustained hard use, also accelerates bearing wear. Before fitting the new turbo, the oil circuit, hose condition and air intake cleanliness should all be checked to prevent premature contamination. On start-up, it is recommended to prime the turbo with oil to ensure immediate lubrication of the internal components from the very first engine revolutions.
