My 2009 C70 2ltr diesel is running on 2 cylinders. I have changed the ECR, renewed the injectors, changed the EGR valve, and changed the camshaft position sensor to no avail. There are no engine fault or VIDA codes showing. There is 1.5v present at each injector and a Noid light test indicates am activation current at each injector. The car was running fine one day then switched to 2 cylinders the next time it was started. I am running out of ideas - any suggestions?
Thanks
Vic
