Hi all. I wondered if you could give me some advice please. I have a 2005 Multipla JTD and it keeps cutting out. The engine management light keep coming on but no codes can be found by the garage. They've ruled out heater plugs and fuel relay. They are looking at the ECU now. The car starts drives for about 5/6 miles then cuts out and won't start again. you leave it for 10 mins and then it starts. The car as been fantastic for the last 5 years but now its causing a headache.
