Revs not quite right

[vroomrs4]

Hi all
When I put my foot down on the excelerater The revs go up as normal but then when I take my foot off the revs hangs there for couple seconds which doesn’t feel right, has anybody else had this problem,
Someone said it could be the clutch switch.
Advice much appreciated.

We have the same problem - changed the switched no change changed the MAF sensor its fixed other things but not that

Switches sorry

It might be the PCV valve as it will have perished over the years, it's mounted under the carbon fibre RS engine cover.

Good suggestion

Great, i'll have a look at that.. Thank you

Yes best way to test pvc is remove you oil filler cap with engine
Running if it bogs done and almost cuts out your valve if definitely faulty hope this helps

[vroomrs4]

Thanks for that tip..

No worries I know this cuz mines has failed last week so in the process of stripping down and carrying out carbon clean too
Also I have ordered spaces for inlet manifold that's ment to
Make a difference too so we will see

are you sure? read elsewhere on here that the rs4 b7 still does that with a new valve fitted? ....

Based on my experience, yes it still bogs down some but far quicker recovery and although mine did not shut down engine when it failed/was replaced, it almost stalled. So before and after was still noticeable different, upon change.
