hmm, did the battery/oil lights come on when all this was going on? were the engien revs actually bouncing or was it just the dash rev needle doing it

no other lights mate and it was hunting about just had oil and filter done with fully synth 5w 30s and a new fuel filter also noticed some arse has drilled the airbox too

Get a new temp sender.  Easy to change and you can at least rule it out for the sake of £10.  Don't be tempted with a cheapo ebay one, go to Euro or VW for a genuine one
