thats wot i thought it might be, have to get it on my mates diagnostics, cheers.. now i got a noise from the front, noisy drive shaft maybe????? it goes under load but reappears when i take foot off accelerator, any ideas anyone please.. also lifted bonnet last night to find oil sprayed around and noticed hole in cam cover above timing chain, almost like the hole had been drilled, anyone heard of this before, maybe a fault in casting when it was made??????
