I'm having exactly the same problem, but also with hillassistant warning light. Fault has occured everyday 1 or 2 times since last saturday when I bought my
MCS Clubman -07. It's still under guarantee so hopefully it will be fixed at friday. This fault isn't nice to have in here Finland during the winter time...
I'll let you know what was the problem, if they (service mechanics) will kindly tell me.
