Information
•
To prevent unnecessary repairs, it is important to distinguish between the high-pressure pump and
balance shaft bracing wheel when trying to pin-point the source of the noise.
•
A Nr.172 - stethoscope, for example, can be used to pin-point the noise sources.
•
If you cannot be sure that the high-pressure pump is causing the noise, the noise analysis
must be carried out using the stethoscope on the high-pressure pump of a comparable
vehicle.
Work Procedure: 1
2
Start the engine.
Nr.172 - Stethoscope must be used on the high-pressure pump  Contact point on high-pressure
pump -1- and then on the engine housing  Contact point on engine housing -2- in order to find the
rattling noise.
If you can clearly hear the rattling noise at the contact point on the high-pressure pump  Contact
point on high-pressure pump -1-, stop the engine and continue fault finding. Something else is
causing the fault.
If you can clearly hear the rattling noise at the contact
point on the engine housing  Contact point on
engine housing -2-, stop the engine and continue with
Step 3.
