When you did yours Mr Bigglesworth did your sensor look like mine (nothing between the two metal prongs. Pic is on Post 12) because i still dont know if thats right Thanks.

Ok Is your car running fine then? Cause mine aint boosting properly above 4k rpm, also i thought there is supposed to be some kind of thin wire or resistor between the metal prongs on maf sensor. Hopefully there aint so i can rule the maf out then?
Not sure on the size of the Torx But i used a small flat head screwdriver and wedged it between the grooves and it undone fine
Cleaned mine the other day. There are two types of secuitry Torx bits - sharper pointed ones (type that hold the headlight in) and the more rounded ones that hold the MAF in.
I tried three different ones before finding the right type. The are made by Laser and I picked them up from my local car parts place - think Halfords do Laser as well.
Pretty sure it was a T27 - can check tonight if you want?

...been out and checked and it was a TS25 bit.
Just make sure you don't buy blind and try the bit first, as I say I tried several bits before getting the right one. A Laser T-bar didn't fit but Laser 1/4 bits did.

Well I know on my last car (nissan) it did have a thin wire element, but my leon (tdi) doesn't have it and my car drives perfectly. Of course that doesn't necessarily mean your maf isn't duffed, but physically it appears normal. Best idea would be to get someone with vag-com to sit in the car and then pull up the vag-scope, and then compare the 'expected' Maf graph readings with the 'actual' graph while driving - if they're fairly similar you can rule the maf out.
Did cleaning the AIT and Maf cure poor MPG?? im going through the same problems right now

don't use carb cleaner! It leaves a residue. They make sprays specific for MAF cleaning.
Yeap there's two types of security torx, hexaganol, (6 sides) or pentagonal (5 sides), I think the MAF was 5 sided. Whilst using the correct bit, the bit broke and snapped off, so I just used mole grips to undo the screws, cleaned it, and revs settle down a bit better.
sorry to thread steal 
was wondeirng how you cleaned the sensor? did you just spray the alcohol on then let it dry out?
cheers bud

I took my MAF off and then put the sensor in a sarny bag, sparyed in loads of electrical contact cleaner, held the top of the bag and the sensor and gently shook it for 10 minues.
Cleaned the the MAF tube using spray, whipes.
