2010 Volkswagen 2. 0 turbo dsg fault. The vehicle has begun exhibiting dangerous random/unintentional shifting into much lower gears, or possibly even neutral at various speeds under light or no throttle input on two separate occasions thus far. The first time it happened the vehicle was traveling about 25mph, and the dsg transaxle downshifted/shifted into neutral for no apparent reason, engine revving to 4-5 thousand rpm. This happened roughly four times before it resumed normal operation the second time it happened was yesterday afternoon, on the highway with speed control set at 58mph. Vehicle shifted all by itself without reason, again revving to 4-5 thousand. This time it happened twice before returning to normal operation. Additionally, one morning I accelerated from a stop with cold engine/transaxle in drive, and the transaxle would not upshift from low gear for about 3-4 seconds. Not sure if this is related, but I suspect it may be. The first time it happened, the abs/esp light flashed and remained on, and I took it in to the dealer explaining the problem, and they said my rear wheel speed sensor was failing. This is the only indicator of any fault that I can tell. When the car exhibits this fault, I do not notice any flashing gear indicators or anything of the sort, everything seems normal, except the engine revs high all by itself. I do not have any photos or video evidence of the fault as of yet as it's very unpredictable and intermittent, but I will attempt to capture the problem if I can in the future.
