This has only just happened and i havn't got a clue whats going on
my car was ticking over quite nicely at 1000rpm then for no reason it whent to 1500rpm and stayed there.


my car normally boosts at 1 bar but now i can only get 0.5 bar

i had the car in second gear at one point and throttled the accelerator to make distance from someone who was on my rear bumper i herad the dump valve then the revs dropped to 1000 rpm and i got full boost back for about three minutes then the revs picked up again.


Could it be the dump valve?
could it be a faulty air sensor?
could it be the alternator?

Please help its driving me mad!!

Cheers all

Ian
