Removed the MAF sensor tonight to fit a Pierberg unit. Was going well until I tried to fit the new one. Wrong end ! Gutted as I'd checked the forums all over the place to get the right part number and as it's an electrical item, non refundable.
Anyhooo ..... There's a sonsor on a wire on the old MAF and I thought - fairly sure it shouldn't look like that. Took a toothbrush to it and gently removed some really baked on grime and crud. Back to silver and replaced it.
Car seems better now.
Just need to get the engine management light to turn off. Was thinking about disconnecting the battery for 30 mins or so. That should reboot the ecu too.
Will that clear the light do you reckon ?
