Hi all Does anyone have scope waveforms saved for this system? In particular the MAF, MAP,3rd injector reference etc. This vehicle has come to me after having a MAF fitted by another garage that has made no difference to the fault which is a momentary misfire when started from cold and an occasional glitch under hard acceleration. The MAF shows 2.25v at idle rising to 4.75v at full speed and i feel this is not correct and suspect a cheap after-market sensor has been fitted. Any waveforms from a known good component would be appreciated so that even if my suspicions are incorrect i can test the other sensors. Thanks for your time Allan Davis atdmotorservices@aol.com

Alan 2.25V at idle is too high From memeory 1.2-1.7v at idle would be a more plausible voltage. I would replace with genuine maf. Mark

Thanks guys I will get the car back in when the fault gets worse.I still am not convinced that the MAF is causing the glitch. I am waiting for VAG-COM and a CODA fuel flow/pressure tester to come but if you have any other waveforms specific to this engine code i would be very grateful to if you would attach them to an e:mail and send them to me. My e:mail is atdmotorservices@aol.com
