Just gave the MAF a clean after installing the Gruppe M and totally forgot which way up the MAF goes back in! Does the wire part face downwards or upwards?!
Stupid question but thanks for the responses hopefully!
I thought if the screw holes align then it's the right way - as I've fitted it upside down in the past but couldn't get the screws back in. Flipped it 180 degrees and they lined up perfectly.
Could well be right, I'll check when I get back.
I was sure the wires face down but had a look at a MAF cleaning guide yesterday and the guy appeared to show in the picture the MAF wire bit facing up on the way back in....hence the confusion!
