Hello, I have finally joined the S3 8L gang after wanting one for so long. I am extremely pleased with the car so far during my ownership, but have recently encountered a few faults, one of which has just occurred which is rather alarming. Current faults are; Intermittent Cooling Fans - Should these run all the time, when stopped or when the engine reaches a certain temp. This has caused one temperature overheat warning so far, when I was outside talking to my mates with the car on idle. Brake Squeal upon low speed 'feathering', it has Mov'It front brakes and new callipers/pads/discs on the rear. (I have been told that filing the pads lightly and putting a leading edge on the pads could solve this) The new alarming fault - It seems that the car is loosing power, the power seems to drop off for a moment or it feels as if the car is juddering. Drivers side window doesn't wind down, no sound of the motor attempting it - When pushed in the 'up' position, the motor is activated, but then senses it is already at the top, and stops. The car has been MTM tuned prior to my ownership, I thought it may be turbo related when I first noticed it on 'boost', but now I have realised that it even does it at low RPM in first, etc.. Any assistance would be appreciated folks, thanks!
