Thank you for answering my question. I have all the factory BMW tools to install the camshaft chain and VANOS. If I had a timing issue there would be a code for the intake camshaft too. But, I found out that the signal from the exhaust cam sensor from a good running car with the same exact engine has the same exact signal that I have. I diagnosed the continuity of the yellow, brown, red, and white wires and the continuity was perfect to the DME. After further speculation I believe I must replace the DME. prior to this test I had replaced six sensors (2 BMW originals and 4 from SSF) and it didn't make any difference. I checked the gap between the intake cam sensor and the cam and between the exhaust sensor and the cam and I realized there was a gap of 30,000 of an inch. What do you think?
