Noise when lift foot off accelerator

[mr-bungle83]

As title says, on my 147. Any ideas?

I get a reverberation on the over run at certain revs. I have put it down to the exhaust flexi pipe starting to give up.

What sort of noise?

[mr-bungle83]

Sounds like a wobbly noise. I think it may be one of the wheels. The sound gets a lot worse as im driving on the motorway or a dual carriageway and i lift my foot off the accelerator. Ive literally only just had a full service and mot done last week. I plan on taking it back to the garage this week.

Check the whole exhaust system-most propable cause

is it a "higher pitched" sound? I had that ... turned out to be the CV Gaitors, my sound would usually come in at about 2000rpm down to about 1500 ...

No its like a wobbly sound, a bit like the sound when rolf harris gets his wobble board out.

Another thought - flapping undertray?

Yep that's the sound (by "higher pitched" I meant not a very low pitch sound), with mine I just left it (because I didn't know what it was) ... until the CV gaitors failed the MOT, after they were changed the sound went away ...

that's what I thought mine was at first ... but then I changed it to an Ali one and the sound was still there
