    Have you checked that your Anti Roll Bar isn't rubbing on the driveshaft? Not sure if this would cause an ABS light fault, but in my experience nothing is beyond the realms of possibility.

    Common fault on the A3 when lowering as it has a VERY different ARB config to the S3. If you're getting rubbing and juddering noises I would definately check. Likely to be the O/S as it has a driveshaft much thicker than the near side due to the length... But could be the cause on the N/S.... Worth a look for the sake of the 2 mins it will take you.

    the noise you're hearing is your ASR kicking in mate, it's a very simple form of traction control that tries to apply the ABS when it feels the wheel slipping.

    It sometimes triggers when pulling away from junctions and stuff over steep cambers, but it can also happen if you have a dodgy wheel speed sensor on one corner. usually the front. When mine started playing up, it was triggering all over the place at any speeds up to 30mph.

    How have you replaced a sensor already if you didn't have VAGCOM to tell you which one was at fault?

    I had this at any speed under 5mph when i used a Euro Car Parts wheel sensor instead of an Audi one.

    Steve reply to the PM i've sent you and we'll VAGCOM your car this weekend and get it sorted.
