So I get in, start the car and stick it in reverse (DSG gearbox) on a slight incline, release the brake and hit the accelerator... car rolls down! I try again, and once more the car simple rolls down with no feedback from the accelerator and no reverse motion whatsoever. At this stage I'm inches from the car in front and alarm bells are ringing so I stick it in P and hit the accelerator to see if it revs, and nothing at all, just idles. Turn her off, switch her back on and everything's fine again Any ideas what on earth went on? It's a 55 plate DSG if that's of any relevance.
