Hi all. 02 D2 4.0 with 90,000 miles on her. Started suddenly making a racket when accelerating. It sounds like a very noise tappet, but it could well be pinging its arse off. Given that it comes and goes I reckon its pinging. It had a new MAF a little while back and has been running well. Apart from the ticking it runs hard on both LPG and petrol. I wonder if a knock sensor is playing up (or my new MAF has gone south!).
Any assistance greatly appreciated.
Cheers
