Anyone have any idea what causes this? only comes on around 3.5k/3.75k in higher gears e.g. 4th onwards.

Its a Cupra TDI.

Also when i start my car from cold my car doesn't seem to 'dump off' until 1/2minutes after driving, thought it was a broke dump valve but no sure.

Any help would be grateful

Thanks David

Not sure what you mean by "dump off", diesels don't have dump valves. My guess is the MAF looking at what they says.

Thats what i thought so i put it in inverted commas. Could this be the reason why its seems to have lost power etc?
