Can anybody point me in the direction of a 'How to' change my MAF. Also any do's and dont's would be appeciated. I know I might sound stupid, but I want to do it myself, and I have never done anything like tthis before.

Should just be a case of unscrew the MAF from the intake housing, install the new one then do a throttle body alignment by either removing the batt neg lead for a period of time so that the learned values are cleard OR use vag com and instigate one.

Hi Paula
I have changed/cleaned/removed the Maf on many occasions, including when changing the air filter on a regular basis. It really is a very simple job.
1. go to an audi dealer and get an exchange deal on a new Maf (i.e pay approximateley £90 for a new one and receive approx £20 refund for return of the old one.
2. Unclip sensor cable, undo jubilee clip to concertina hose, undo two spring clips securing MAF to Air Box ( be careful that they do not pop and get lost down into the heat shields)
3. remove old MAF ( be careful to leave large rubber o ring in place)
4. reverse process with new MAF
5 Recconect sensor cable
6. Restart car and enjoy improved performance whilst taking old Maf back to Garage and collect refund
Job Done - No callibration or throttle body reset neccesary
Possibly the easiest job on an S4
Regards
Jimbo

I'll have to try that lol
. Only thing is now it's going so well, I keep thinking to myself "I wonder what it would go like if it were chipped"

It goes infinately better!
Effortless overtaking even in 6th on the motorway!
A remap lets me be lazy, no cog swapping and still loads of oomph.
Although, when I fancy a blat with cog swappage I can't help but giggle.
In my case my first S4 was remapped, this one I have now isn't (wrote my other one off
) and in comparison it feels dog slow.....

Get it re-mapped Paula - you'll wonder why on earth it took you so long to do it once you've had it done ...
... it's the best bang-for-your-buck mod you'll ever do ...

Sorry I meant Re map, not Chipped. Had a slight 'blonde' moment.
