VCDS will drop out initially and then take a few seconds to re-establish coms with the ECU and then when coms comes back, you need to view what the rpm is; it MUST exceed 280rpm for a clean start. I keep going for about 30 seconds to get a good idea of the average starter rpm. After the test, don’t forget to reconnect the head harness and clear the codes you will have generated.
Hey bud. I have no doubt in your knowledge of cars so sorry for this blunt question.
When I have this issue and I try to start it, it throws some sort of oil pup error stating to stop the engine. Think it might be oil pressure or something. (Surely because oil pump isn't running) I think this happens after around 10 seconds of cranking.
If I do it for 30 seconds, isn't it going to cause harm to the engine?
