So I don't think I shouldnt own a car!! Went to Goodwood today great day out. Great drive down and almost home!! Got about 4 miles from home and stopped at a mates house. Went back out car starts but runs like a bag of nails. Called my brother who is a mechanic (well diesel fitter trucks vans and stuf ) plugged in his box of tricks and it came up with error code p1633.witch after later investigation is a.... throttle valve adaption limp home position. Or adaption condition not met. What on earth dose that mean?? Any help would be great
