Good day, this is my first post and I’m pretty new in the Volvo community. I have a V 70 Bj 1997 gasoline /automatic 104 KW 270,000 km With me the service signal lights up. We can read all the ECUs via OBD II except for the engine control unit. This is not possible for some reason, there are no errors indicated. Otherwise everything seems to be fine. I have now written a repair service because the car the exact symptone as on the n Homepage described shows and wanted the engine control unit to be repaired there. However, I was told that I should have a workshop checked beforehand if it really lies on the control unit. Described Symptone according to homepage: “Different failures of the engine control unit, the vehicle no longer starts or goes out during the ride. The vehicle wobbles and runs restlessly, it comes to ignition oscillations. Usually also the yellow error indicator “motor electronics” lights up. different error codes – depending on the defective output or you can no longer communicate with the control unit ECU can no longer be read out” I only get to wacklern and the car runs restlessly between 80 – 100 kmh. Since I want to make a longer tour through Europe want to have the whole before repaired. My question, is there anything else that I can check before in such a case, whether it is really the engine control unit? Many Gs Rüße, Roland
