Just got off the phone with JKM and the S3 is going in next Friday to have some diagnostics carried out. I have a couple of issues with the S3 which I've been trying to solve myself but failed so far, so it's time to get the professionals to take a look! I've had a slightly lumpy idle since buying the car. It's had a few bits replaced including a big chunk of PCV hose but that hasn't helped at all. Also in the last couple of months (think it's since cleaning the MAF) the car has been feeling underpowered. When pulling away from a junction it feels gutless..a bit like it did before the remap! I can hear the turbo spooling up at around 2k RPM but there's not as much power as there was the day the remap was carried out. There's also a hissing sound if I accellerate on the motorway which I think may be a boost leak..it certainly sounds like a leak of some kind. Fingers crossed JKM can work some magic and get her back to her former glory!
