Erase them and see which ones come back first, unless you want to spend money on every single fault, which i doubt.

Charge pressure negative deviation... I had that and it was a boost leak..

16486 look like a maf fault which could be causing some of the fueling faults

Hi guys thanks for the replys

I have a new maf on order now so will see what that brings or clears should I say
As for there being a boost leak it doesn't feel as pokey but still reads 1.25 bar when boosting on the gauge. Could there still be a problem? If so I guess changing silicon hosing for the bypass and such would be first option could anyone tell me what size or does anyone have some I could give u a coupe of quid for through paypal?

Cheers again
