    Not sure on the brake cleaner, think IPA (isopropyl alcohol) is recommended.

    I'd use intake cleaner just in case. I did mine with intake cleaner and no issues to report.

    just done mine with contact cleaner from maplins. Didnt have the correct torx security tool so used some grips on the raised screw head took forever but saved me buying more tool bits ill use only once. Cleaned up the MAF housing as well as inside of that was pretty dirty, car seems to run smoother and the 'missfire' i thought i had has gone.

    Nice! I attempted to do mine but had the same problem with the security torx, went to buy one from Euro car parts and they don't sell them :(

    Oh well will have to wait till the weekend now to do it and while I'm at it I shall clean my trottle body too.

    I brought a security torx set today froma cheapo diy shop... It's meant to be a t25 torx to undo the maf sensor screws but the damn holes on the torx I brought are not round (too small to go over the round bit in the torx screw) enough so still can't get mine off, im thinking it must be a proper Audi torx I need?

    Or i have a **** security torx set.

    Gutted :(
