engine acting strange????

[AUDIS2avant]

Am having a few probs with the car.
found out yesterday that the piping to the dv wasent connected and hose to maf-turbo had fallen off, so after fitting them back on (and making sure they dont come off again) the car sets out when coming on full boost????????
It´s also having problems on standstill but not sure this has anything to do with anything tho.
What you guys think?
Have taken the batteri off for a few hours to reset the ecu, but will it be enough?

Just done some more testing, all pipes are ok, all vacum pipes are ok also.
I can Cheat it a little bit by controling the boost with the accelerator, but it keep coming when i just flor it?????
Also when coming in to a letf or right turn and pressing the clutch, the engine goes out some times, mystery getting bigger now

Today i was out again after trying to find the error, and it also does this under light load, say 0,2bar @ 2200rpm and again 2400rpm, can this be a MAF error or maybe the fuel pump / filter?

Hi mate,i think this is a common problem with s2,s.I think you should concerntrate on the MAF.

david : thanx m8, have already ordered a new maf, just in case.
Hope to resolve it this way.

MAF sensor is the most critical device on the S2 engine... Just catching up with this post now. Good man !

Think I might have a similar problem!

Having trouble ideling usually when the car is fairly warm - it keeps on wanting to stall. It's a fairly intermittent problem but definitely seems to becoming more frequent. So I'm thinking after reading this post and a few others that a MAF sensor would be a good place to start?

If that's a good idea can anyone recommend where to get a MAF sensor from? Also is it an easy enough job for an amateur?!

Sorry for the thread hijack!

[Colesy]

Can anyone help with this?

Thanks

Will : give quattro corner a call, and yes, it´s a 10min job WERY easy to do.
And btw, mine had thoose problems too, idle trubble but mostly on warm engine
