ALP16 Engine rattling, noisy engine, turbocharger noise
NOTESOnly address this customer complaint after a complete check with the diagnostic
tool.
If the noise is coming from the turbocharger, apply the Technical Note 5164A, Fault finding of noises.
Note:
Pay close attention to faulty components that might result in unjustified replacement of the turbocharger. For
example, whistling does not necessarily indicate damage to the turbocharger (this could be coming from the
exhaust, the timing, the gearbox, etc.).
Check that the fuel tank is correctly filled and that the fuel is correct by running TEST 13 Diesel fuel conformity
check.
Check the levels of engine oil and coolant.
Is the compression in order? Carry out the necessary repairs.
Check the electrical conformity of the heater plugs (the resistance value of the heater plug must be less than
2).
