Please can someone help me. I've got a 52 plate 2.5td warrior, and when I stop at say traffic light for the first time on a journey the engine light comes on! I've had it plugged in to laptop and said low pressure boost sensor, so this has been changed for genuine part.but the light still comes on. If you look at the actuator it is going in and out all the time , which you can feel when driving. So you get boost then none then boost then none and so on. The actuator solenoid was change end off last year with none genuine part.
Has anyone else had this fault and can help me please?
