I forgot to mention on the previous posts that the engine sounded more like a diesel than a petrol when it came in & at one point when I was accelerating the engine, I heard a thud on the bulkhead. After stopping the engine to check & looking underneath, I found a bit of plastic, which had come from the timing cover where the centre of the balancer sprocket on the rear camshaft had come through. I spoke to the customer and he agreed to carry out the camshaft repair first & then carry on testing for the fault as I didn't think that the camshaft fault was the cause of the intermittent cutting out. After driving the vehicle for about half an hour, I couldn't get it to cut out, so rang the customer, so that he could collect the car. After it had been stopped for a while & just before the customer turned up, I tried it again & sods law , it cut out, but I couldn't get it to do it again & when trying to check the faults, I got the error message again & an unknown code.
The customer took the car with the understanding that the fault would probably re-occur, even though the camshaft repairs had been done & it now sounded like a petrol instead of a diesel. So far I haven't yet heard from him, but perhaps he has now decided to take it somewhere else.
I will post again, if I get to see it again & sort it. I am suspecting an ecu supply/ ground fault now , due to the fact that it is unable to display the fault correctly, but it's only a guess as I have yet to catch it faultering.
Kind regards,Andrew
