I have an issue with my car that only disappears when the MAF is unplugged. This causes the engine management light to stay on, will they fail it because the light is on? Unplugging the MAF is the only way the car runs perfectly, it loses power when it's connected.

Nope, engine management light is an advise at most. The only way it could fail is if because the MAF is unplugged it emits excessive smoke for the smoke test.

Have you thought about buying a new MAF to fix the problem? Surely your car must be using more fuel or running less power with the MAF anplugged!Originally Posted by arthurfuxake

Some MOT testers may refuse to test it if an EML is on. For the smoke test the throttle has to go to maximum. A tester may be reluctant to do taht in case he causes more faults or something goes bang. If he's doing his job properly he will see that on his pre-test checks give you the option to take it away before he logs it on for test. The light being on, in itself isn't a failure though. Will be after January 2012 though.

Yeah, it's had 3 new MAF units. It has almost zero power when plugged in, but runs better than it ever did with it unplugged. Better fuel consumption in summer, slightly worse in winter. Swings and roundabouts I guess.

Are you using genuine MAF sensors or have you been replacing with pattern units?
Genuine.

I would check the wiring on the connector/plug for the MAF unit then. I think you can buy these seperately, I remember a member writing a 'how to' on how to replace the whole plug actually, but not sure what section it was in though?
