I have had this problem for a while but I have just been on a trip to the Dordogne and the vibration from braking for the many French roundabouts was really getting a bit unpleasant. The Tom Tom was literally just about jumping off its windscreen mount! I was wondering if anybody else has this problem? The car is a Plus Four YM23 auto. The dealer has acknowledged the vibration but did not resolve it other than cleaning the Discs. Warped discs would be an obvious cause but I am still not 100% it does it all the time especially when cold and driving more slowly. I did wonder whether the brakes were fighting the gearbox in change down but free wheeling in neutral is inconclusive. I have also switched off the ESC and stability control to no result. Stepping into a "normal" car is night and day! (no surprise there then!)
Another niggle apart from no light in the clock is the heater control button on the dash to divert air to the footwells. Mine does absolutely nothing. Does anybody else's do anything. Is it connected to anything?
Any observations welcome!
