It all started back in December.....the ASC and EM lights came on and the car was driving really rough, struggling to get up the gears, was shaking and sounded like it was misfiring. Called the AA and they diagnosed with the following fault code using Bosch diagnostics: System: Engine control 1 -72P / Diesel EDC 15P464A - Solenoid valves for engine mounting. Error Message: Short to B+.469A- Valve for unit injector, cy;. 1. Error Message: Circuit defective.
The AA advised injector 1 required replacement and cleared the codes. Following clearing of the codes I took the car to a garage. As the car was not showing faults I was advised to continue driving it until it developed again. When it did I was advised to try fuel additive to help clear the system, as it could be a fuel issue. However, the problem continues and I am now being advised to replace injector 1. When the issue occurs I can pull over (sometimes tricky to achieve!), switch off the car for a few seconds and it will all reset with no symptoms....until it develops again - however seems to be developing quicker and more regularly now. My query is - how can I be sure a new injector will resolve the issue (they are pretty expensive for trial and error!)? If the injector was faulty then surely the symptoms should show all the time and not intermitently?
The car has covered 150k miles and if I can get through this will do many more!
Any advice would be appreciated as would contacts for reasonably priced injectors!
Many thanks, Dave
