Hi!

Looking on here I've read lots and lots about these MAF Thingys, and how important it is to buy a good quality OE one rather than from fleabay, but as these things are three figures and I've got tax and MOT to sort out at the end of this month, can anyone point me in the direction of a DIY guide for reconditioning the things?
I'm a trained electronics engineer used to dismantling and reconditioning circuit boards with small surface-mount components by the way!!!
Failing this, if they're of sealed non-repairable construction, is there a Bosch Part Number I can look online for the best price for?
