As the MAF is subjected to the air that is drawn in via the intake and assuming you are 100% sure the MAF is the problem you would have to assume that it's the intake/filter at fault.

not 100% sure its the maf just very confused have been running the original airfilter that came the ebay cai was wondering if this could be at fault?

Maybe worth cleaning the throttle body.

HTH

The ebay CAI filter is crap imo, it does not filter out enough dust. I noticed this when i went back to the standard box and filter, the turbo intake hose which is located after the Maf had a fair amount of dust lining it.

Either get a better filter, decent panel filter or go back to oem and replace regularly.

anyone able to suggest a cone filter that will fit on the ebay tube

does your filter need to be oiled for it to work ? Just asking as I was informed yesterday that it is advisable to wash a new pannel filter to get most of the oil of as it can damage the MAF sensor as it is drawn into the engine.

I'd say the filter is the most likely cause. Any filter that requires oiling will cause damage to the maf over time. Washing to remove most of the oil is a good idea, however all that does is delay the problem.

its been on car for approx one and half years and wasnt oiled

its been on car for approx one and half years and wasnt oiled

Mine was on for 6 months, i never oiled mine either....dust galore :thumbdwn:

Didn't knacker MAF though but i did clean the maf on seeing the dust in the intake, car idled a lot better after

new filter then i think
