I have a 2009 C320 CDI sport auto that today decided to switch itself into sport and then stay there..The sport button stays lit up even with the key out of the ignition and pressing the button does nothing. The gearbox is in sport so it is not just the light staying on..
Does this sound like a trip to the garage or is it simple disconnect the battery to reset the gearbox?
