firstly, ill just say its good to be back, have just picked up another s3 after three years with just my van to run around in. secondly, however im a bit disappointed to be having problems already, after just 2 days. sorry in advance for all the reading. i jumped in the car this mornin and it wasnt hitting full boost untill about 4000rpm. iv still got my old vag com(shareware version) so i plugged her in and came up with the following faults, 17544 (fuel trim bank, running to lean) and 01542 (yaw sensor). probably not related i know. any way i cleared them and they came straight back up. The first thing i thought of was maf sensor cos i know there prone to playing up on these, so up came the bonnet, took the maf out and gave it a clean, (contact cleaner, not meths or some ****)put it back in and was no different,so up came the bonnet again and had a look around and fairly quickly found a split in the intake pipe about 15mm long which must have happend over last couple days cos it was boostin fine when i picked her up. so obviously im gonna need a new intake pipe. any way iv sealed the split the best i can and hopefully it will see me through till i get a new one, but now im thinkin my maf is knackerd aswell cos after driving again iv got irregular boost, sometimes kickin in at about 3000rpm and sometimes not till 4500, and also the engine managment light came on, iv plugged vag com in again and iv now got faults 16486 (maf sensor low signals) and 18448 ( am not quite sure about this one).and the other codes have gone, iv managed to get the managment light out but is still not boostin right. also my one touch windows are now playing up, working sometimes and not others.( doubt thats related but still a pain) am pretty pissed off cos been waitin a long time to get another of these and its doin my head in already. am really hoping these are just small teething problems and not gonna be a costly pain in the ass. all these different problems seem quite random so am hoping its not the ecu or something. any way i appologise for all the negativity but im sure you understand my situation. lol any input would be greatly appreciated, i know the first thing is to replace the split pipe so any info on what to get and where from would be great. cheers guys and will get some pics of the car up.
