D5 running bad / misfire
Hello,
I'm Maarten, from Germany. I've V50 D5 with 355.000km, second owner. Untill now the car has been running fine, but for the last 10.000km the engine is running (partly) bad. Let me try to describe the issue with more detail. when idling, the RPM is not stable, and you feel the whole car shaking. Driving without the need of much power is the same, the whole car is shaking. The intersting thing is, when you perform via VIDA, the test RPM per Cylinder, the engine runs fine, as did it came out of the factory yesterday. As soon as the test finishes, the engine starts running bad again. what has been changed so far: Fuel filter (Volvo) Air filter (volvo) LMM (Bosch) Lambda (Bosch) Fuel pressure sensor (Bosch) Fuel presure regulator (bosch) Fuel presure valve (bosch) Fuel presure equels the desired fuel presure. engine runs fine under load and above 2700rpm. Firering up the car, the first few seconds it runs fine. Sometimes there is a 100km 'window' it runs fine under any condition. Car is ran with Shell Vpower diesel. Volvo wants to change the injector connectors and reload the software on the car. 2 general shops, said sorry no clue. I am hoping one of you recognises these syimpthoms, or experianced the same. As i don't see logic in the above. Due to the perfect running while performing the test in VIDA, i suspect something electrical, and not the injectors. Looking forward to your responses Kind regards, Maarten |

sounds like a variation on the better results when on test syndrome...
Look at the EGR. I just sorted out a 1.6 that had numerous seemingly unrelated faults, which seemed to get worse when the faults were cleared... changing the EGR actuator sorted it out.. so far so good... |
