I’m also tempted to suggest that coolant control modules and thermostats will also assist in this endeavour. Mechanical engine condition Mechanical engine condition can be established with a simple range of tests: Relative compression Cranking current and rotation speed Injector balance or correction Comprehensive picture At this point we should have a pretty comprehensive picture of the vehicle operating conditions. Good fuel quality, and the correct choice of filtration and oil are critical if premature turbo failure is to be avoided. At ADS we do conduct engine flushing as part of the service package. Carefully examine the fuel filter before discarding. I believe EGR valves and injectors do have a finite life without waiting for failure to occur first. We find that rubber control hoses and intercooler circuits deteriorate causing restriction or leakage so look carefully at adaption or correction values. These should be in the region of: + - 2% normal + - 5-10% concern + - 10-20% serious condition If you discover correction, then there is a fault requiring attention. SCR systems SCR systems require further consideration. Problems are common with injector nozzle fouling, dosing pump failure and no additive. Pump pressure can be checked with a gauge, and injectors can be tested with a range of existing injector test benches. The implications of this list will add a great increase in cost, as technicians we should focus on requirement and process not cost! The customer owns that responsibility.
