ALP16 Engine rattling, noisy engine, turbocharger noise
NOTESOnly consult this customer complaint after a full check with the diagnostic tool.
If the noise arises from the turbocharger, apply Technical Note 5164A, Noise fault finding.
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.
