Got this code yesterday and car went into limp mode.
It happened when i was doing about 50-60 mph and put my foot down
After switching car off then i restarted it and it was ok,never had the problem over the next 35 miles of driving.
Thort id post it on here as ive had this issue before,but not very often only once say every 2 months of driving.........is it common/normal ( i use the car once a week) on this occasion i used it after 2 weeks.
