Hi, thanks for your reply! I've only owned the car for 7wks, it was an ex demo car at an Audi dealership. I've had the car into my local Audi dealership, who found a fault adjusted the sensors, which seemed to work for 2weeks, but then the 'sticking' started again. After lots of backwards and forwards with the dealership I purchased from they eventually came to collect the car and left with me a courtesy car whilst they took my car for investigation. The courtesy car (A3 saloon with electronic parking brake) was absolutely fine, no issues with the parking brake. The dealership told me they couldn't find a fault but had changed the rear brake pads and discs as they were blue from overheating, which suggested it had been sticking. I got my car back and again all seemed great, until 3weeks later, it starts sticking again!!! It's just so frustrating. THe dealership are now getting snippy with me and telling me there is no fault as they couldn't be find one when they took the car, be don't seem to be understanding that it's intermittent- for example, it was sticking this morning, but driven perfectly this afternoon.
thanks, Kirstin
