does it over rev when you put the clutch in to change gear at all? if so i suspect clutch pedal switch.. if not then a throttle body clean might cure it.
Its like i've still got my foot on throttle when i depress the clutch, but i obviously haven't!!
I have to leave a second between coming off the gas, and going on the clutch.
The problem is worse with full throttle, and high up the rev range, so its hard to cane it

I've tried a throttle body alignment, VAG-com shows no codes.
Its been like it for 2 years since he bought it, it had 25k on it then, now it has 45k.
Thanks for any advice.
