C5 2.2 HDi (2001) whirring after stopping

Post by tmead »

After stopping and getting out of the car there is a whirring noise from the n/s rear for a little while. Do all C5s do this ? I'm worried its the eolys pump, as that's the only thing under there ?

Hi Tim,
There have been a few cases of this in these forums but cannot find them at the moment.
As far as I know even if the pump is running it shouldn't be injecting Eloy's as there is a control on the injector system too.

Many thanks for looking that up for me, I'll keep an ear out for the pump noise after I next fill up with fuel. Could be that it will actually try to inject some eolys now, as the faults have recently been reset.

not yet sure if the sensor is actually working......

Could be time to justify buying a lexia kit .....

I haven't heard this running for a while now. The cap sensor has been fixed (see another thread), and I'm working on the assumption that it is now injecting Eolys as it should. The motor and valve both work as they should from Lexia. A blast down the dual carriageway at 4K for 10 minutes has definitely improved fuel consumption, hopefully it will clear out further with another go.

As I understand it, the pump will only inject additive into the diesel tank the first time the engine stops after a fill-up which involves a fuel cap removal, thus it should not run each time you stop the car.
