My 2011 535i valvetronic system has a problem, I’m getting a dme internal fault code. I replaced the valvetronic motor, and wire running to it from dme but can’t run the procedure for it in ista because of the internal fault code. The car won’t start because of the eccentric shaft being at minimum, but when I manually adjust it The car will start. First off I want to know what the issue can be, and how can I keep the valvetronic at maximum without the eccentric shaft springing back.
