Hi, i have an A3 Sline Quattro, manual transmission with an electronic handbrake...just after some advice...  When starting the engine and going to pull away, I am finding that the brakes seem to be sticking, I'm having to rev quite a lot for the electronic handbrake to finally release then the car sort of lurches forward.  It doesn't happen all the time, it's intermittent, but has happened when pulling out of junctions, setting off from traffic lights, and has even happened when reversing
