Need some help, was out in the car about an hour ago and car died whilst driving down road so started her straight back up then did same after about 500yards. Pulled up tried to start engine and all it did was try and start and not fire up. As I waited for me dad in the ranger to tow me back it started up again, but after a minute cut out and keeps doing this. Just before it cuts out every time the triangle warning light with the arrow going around the outside of it comes on. Before it started back up I checked the belts and they was both on. Next thought it could be fuel related such as diesel pump or injectors. Can anyone else think what it could be or had similar problems. The car is a 1.9tdi. Help!!!
