It is easy for the manufacturer to get one part of the "map" incorrect, although you would hope that this would have been found in testing. My worry isthat there is someting actually wrong with the car - the dealer couldn't give me a timescale, but I'll book it in again in a couple of weeks.

Please don't get me wrong, I love this car and the handling is superb. This is just a slight niggle

Thanks for the reply.

Hope everything gets sorted out soon.
