Check your engine bay RH side inner wing plastic cover!
I've been baffled by an expensive sounding buzzing noise. Sounded like a dry steering pump or AC pump. It happened after starting up following a 5 week lay-up. It went away a little bit after some running, but came back when on the over-run, especially in the lower gears. From this I suspected it had something to do with the position of the engine on it's mounts. But it didn't always do it. Also, just before I'd parked up prior to the lay-up I'd pressure washed and given a drying run with no noise.
Today it was time to investigate properly. I noticed I could get the noise to show with the AC on....(a little confused at first as I had the fan switched on and the demister selected, but the AC switch 'off'. As most of you know, this selects the AC anyway). By engaging the clutch a little in reverse gear I moved the engine on the mounts anough to get the noise to show. Do it again with the AC off and there was no noise.
Looking under the RH front wheel arch I could see that the inner wing plastic engine bay cover was pushed in at the bottom (probably with the power washer jet). With the engine switched off, a good pull on the bottom of the cover located the plastic ears on the outside of the sump shield to keep it in position.
Result...ultra expensive engine noise is now gone!
