First trip out, Inverness and back, after being returned by the main dealer - did it again. 4 times. Back into the dealers today.
Symptoms are: Driving along, no problem. Engine suddly becomes unresponsive, loses power, will not rev above 3000 rpm and even that at a struggle. Stop vehicle, switch off, re-start, fault disappears, vehicle runs fine for maybe another hour or two....and repeat. Engine management light only came on once in all of these events - and was not there when the RAC turned up... Happens under any driving conditions from 70 in 6th to crawling in roadworks, I can't identify any pattern or trigger. Grrrr.
