Parping wastegate solenoid??
Posted: Thu Aug 02, 2007 7:40 pm
Hello all,
My recently acquired HDi 110 (2003) makes an odd noise when stopped which might be best described as a parping which comes from the wastegate solenoid valve when the engine is switched off, lasting a minute or two. I can also hear it at low speeds/revs particularly on the over-run. It seems to drive ok though.
I assume the noise is vacuum bleeding off through the solenoid - it stops if any of the pipes to the wastegate or EGR solenoids are removed so there is lots of vacuum there.
I have tried changing the wastegate solenoid for a new one but it still does the same. Has anyone out there with more experience with these systems heard of this before? It's not really a problem at the moment but the noise is just irritating!!
Ta!
