Any ideas Selespeed not upchanging automatically.
ASR & ESP failure after 5 miles or so.
Car just MOT'd. Dodgy connection?
If so look where?

Brake light switch maybe? Have a check and see if brake lights are on.

i had that and it was the break switch, i needed to pack out the gap between the switch and the peddle.

Cheers! Problem solved, obvious when you think about it, all problems affected by brake signal. Have put a few elastic bands around peddle as temp measure. Packing seems like a good simple remedy.
