I know you have to be REALLY careful with it whatever you use.

Just thought I'd take a look online and found these...

First one is from an M5, but the actual cleaning part is probably relevant

This is a youtube clip on an older M3, so possibly more relevant. Note the warning at the beginning!

Cheers guys

I've ordered some MAF cleaner so when it arrives I'll get on this and see whats what. If cleaning it doesnt do the trick I'll steal the one from the M3 and see if that sures it - at least that way I can rule out a faulty MAF

If its faulty you should notice no difference when you run it unplugged....not sure who makes what types but my experience on other vehicles is that the two main manufacturers are Hitachi (expensive but ultra-reliable) and Bosch (cheap but unreliable, partly because of their self-cleaning cycle which can eventually burn the wire out).

True if completely knackered. But running worse unplugged does not mean the MAF is not the problem. Could be returning valid, but improper values.
