Took my REVO'd 2.0FSI T DSG to Prosport in Manchester yesterday to get it on their rolling road. Got it strapped down and running but as soon as he went for the power run, i.e. full throttle from just below 2000rpm in fifth (in manual mode obviously) the revs would build but then at 4500rpm it would change down a gear on its own!!!! This happened in sixth and fourth too but only on full throttle. Notes: 1. Gear selector was in +/- of course 2. ESP turned off 3. This happened with the stock ECU code, we didn't try it with the REVO as the guy wasn't happy with the car doing unexpected shifts on his rollers as it made the car lurch quite a bit. The dash was like a christmas tree because of all the ABS warning lights caused by the rear wheels being stationary. Also the headlight allignment failure alarm was up because of the car being strapped down a long way at the front. They've got no idea why it changes down and it certainly doesn't do it on the road. Any ideas?
