Hello forum, 4 years ago I got a V70 (EZ 2000) with 140hp and 5-speed automatic. It ran up to 4 weeks ago quite trouble-free. But then it started: in mid-July : ETS light when starting the engine control light as well. Then the throttle valve was identified in my workshop as culprit and sent to the company ECU. They repaired it and converted it to Hallgeber. The throttle valve was then installed again. The engine then ran absolutely super super and the switching processes of the automatic were much more pleasant. However, the engine control light did not fail. After a few days of futile troubleshooting, the ABS lamp, the failure brake circuit lamp, the ESP (STC) lamp were added in the course of 2 days. Furthermore, the Tacho and KM counters failed, the automatic arrow flashes and the tank indicator fluctuates (sometimes, not always). The gas acceptance is sometimes a disaster and the automatic simply does not switch into the higher gears. I had suspected the ABS control unit and the topic ‘cold soldering points’, however, as an error message a defective wheel sensor should be reported, but this is not the case. The error message reads ‘CAN-Bus communication disturbed. BCM – brake control unit’. The car is now in the workshop and there the ABS sensors are checked (as well as the ABS rings) and it is generally wanted for a possible cable break at any relevant place. Do you have any suspicions about what it might be? VG mt123
