i will spk up,lol it is a dry k&n filter and was on mine for about 6-7 months (roughly) with no problems at all,all i can think off is that the air flow meter is shot.i dunno weather its because of the filter or not,but i had 1 on my old vr6 what never gave me no problems either,what i would do if i was you is look for a second hand original vw air flow meter,sos if the filter caused the problem,i would be very suprised if it did tho,good luck and heres a link http://cgi.ebay.co.uk/VW-Golf-Vento-Corrado-VR6-Air-Flow-Meter-/200524507457?pt=UK_CarsParts_Vehicles_CarParts_SM&hash=item2eb0
