| Complaint |
Customer complains about some kind of
moaning noise (flow noise) from the High Pressure Pump area. Moan
noise is mainly to hear in vehicle overrun condition with released
throttle pedal and sometimes also to hear during engine idle. |
| Cause |
The most reliable root cause is some kind of
air ingress into the low pressure side of the fuel system. Air
bubbles in the fuel system might cause such a noise which does not
harm the system at all. |

Remedy
In case of customer complaint the fuel filter and feed pipe
have to be replaced.
Please be aware that the moaning noise might no disappear completely
but this has definitely no negative impact to the engine or
fuel system durability.
It demonstrates the current state of the art for that vehicles/engine
combination.
Note:
Do not replace the high pressure pump.
