All direct injection engines have a good working culture and a reduced risk of clogging the particulate filter. Remember that when an engine loses lubrication, even heavy duty CR designs won't last long.
Advantages of the best units in this category
Injector problems known from the initial 2.0 TDI versions are almost completely eliminated in the 2.0 TDI CR engine. Engine culture is very important. Engineers of the CR version decided to redesign the oil pump. It is thanks to this that the appropriate level of lubrication of the drive unit was achieved. The risk of turbocharger or crankshaft jamming is minimal. However, when driving long distances, check the condition of the pump at least once every 150 km. kilometers.
