    Hi all,

    Lots of old posts about this in the search but it all seems to have not found a conclusion.

    I have this problem and as far as i can tell, there are a few options:

    Clutch Switch - Swapped this but no change

    Symptom of a remapped car? - Rang the tuner but they deny this and suggest...

    Air leak? where? Needle in haystack!

    MAF sensor?

    Anyone got any ideas or definate places to look? I notice it happens slightly if you accellerate but instead of dipping the clutch just back off the throttle too

    Cheers
    Ian

    Could it not be a sign the clutch is slipping!

    Have you checked the clutch switch is actually pressed in by the clutch. It may be missing it?

    Yep checked the clutch switch engages correctly.

    It can't be clutch slip as its a definate rev rise as you dip the clutch. Clutch slip would only happen under power etc etc. Two very different things

    It sounds like a common fault but there is no definate solution!

    Will investigate the MAF and air leak ideas

    Mine did it is yours an electronic accelerator? mine is. Is done by a switch cost about £14 or £12 from Awesome Gti. If this switch sticks when changing gears your car still revs. Mine use to red line sometimes when i was changing gear. Aparantly if it sticks your clutch doesnt release properly etc. Ring them tell them your problem they will sort you out in mins. Less than £20 and take 5 10 mins to change it.

    Many thanks for the info. So you're suggesting a switch on the accellerator?

    Yes i think it is wire throttle as its a 51 plate car

    Cheers

    Yes definat mine July 01 plate. Give Awesome a quick ring you could prob have it tomorrow. Mine reved like mad in between changing gears couldn't understand it but changing the little switch fixed it. They changed the switch for me prob 5 mins it took them they said it's common to stick causing over revving etc. Common on R32 so they said.

    Yours will be electronic accelerator like mine. Early ones are cable. The cable ones can use a dump valve ours need a recirculating valve for the car to run properly

    Spoke to Awesome. They say the throttle switch is incorporated into the pedal and requires an entire pedal. They also said this isn't normally the cause.

    Possibly the DV or clutch switch. DV was changed with remap 3 months ago and clutch switch yesterday!

    The plot thickens...

    As far as i believe from what they said. Give them a bell and just say my car keeps revving in between gear change they will know straight away what it is.

    Ring John at Awesome say to him Brent said to call you and say that your car is doing what mine did. Revs increasing during gear change. He sorted me out with the switch.
