A couple of months ago i was driving through town and my sedona 2.9 crdi (03 plate) had what appeared to be a loss of power. No acceleration through gears as if the car had gone into limp mode. Subsequently after stopping the car and turning off the engine the car would not restart. Had the car flat bedded to the garage and this was diagnosed as a camshaft sensor problem (from the diagnostic codes). The sensor was replaced but the car would unfortunately still not start. After some more invest i was then informed it was the ECU as there was no 5 volt output to the camshaft sensor. I didn't really want to lay out the £600+ for a new ECU so i sourced a used part (including all associated parts) from a used parts dealer. This has been fitted and the fault is still there and the garage are still saying it is the ECU at fault.
Although it was a used ECU i find it highly unlikely that two components would fail the same way with the same symptoms. The garage have had my car now for two months and i am hoping that someone might be able to give me a little help on this matter as i am not convinced that the ECU is the root cause.
Some info on the ECU's inputs/outputs would be handy. looking in particular if there could be any other fault that would stop the ECU outputting to camshaft sensor.
