Then impurities accumulate, which shorten the life of the injectors, as well as the diesel particulate filter and turbocharger. The most modern diesel engines equipped with a common rail injection system.

Malfunction of the fuel injection system - diagnostics

Diagnosing an engine failure can be problematic. It is important to know how to properly diagnose a problem. First of all, this may indicate a decrease in engine power.. To this are added uneven idling, black or white smoke, increased fuel consumption and the car stalls at idle.

It may also appear after refueling with low-quality fuel or diesel fuel.

Check Engine is on - what to do?
