Common failures & inspection points

Cooling system leakages and overtemperature

Check coolant level, inspect cooler/heat exchanger for fouling, check water pump for leakages, test thermostat functionality

Fuel injector wear: Worn parts cause return pressure drop, delayed injection

Check injectors for leaks and wear, monitor injection pressure, test misfiring/power loss

Turbocharger malfunction: Worn roller bearings, wastegate sticking, compressor wear

Check compressor impeller for foreign objects/wear, monitor bearing clearance, inspect oil contamination, test wastegate function

Cylinder head cracks/head gasket failure due to high combustion pressures (180–200 bar)

Check cooling water for oil ingress, monitor white smoke development, perform pressure test, perform piston leakage test

Piston ring wear: blue smoke development, oil consumption increased

Monitor blue smoke, perform pressure test, check oil level frequently, inspect exhaust valve functionality
