Hey guys, this weekend I replaced valve cover as my pcv was failing and gasket was leaking and also as I was working close to injectors went ahead and replaced those, obviously coded new values as I have EU5's on top of it did new battery and coded it too, after all the work I did, tried to start the car and... that's when it hit me hard... It was cranking but no start, tried to crank for a while then lost hope, read codes there was a bunch, cleared them to see which ones were not related, rerun scan and found 135608 code which states: Valvetronic system: no movement identified. Can somebody help me out? I'm not sure how that could of happened, when I didn't even touch valvetronic motor in the first place just fyi I got 04/14 bmw 535I Xdrive with 95k miles on it. And did research on the code it seems that this code is not letting car to start. What are your thought or insights? Anything helps, thank you!

When replacing the valve cover, you do have to unplug the valvetronic motor. Check the plug again and see if it was loose. It sit between cylinder 2 and 3

when I was replacing valve cover, I unplugged it and tried couple of times to plug unplug it to see if it makes any difference, tried to start car with sensor pluged in and tried to start it when sensor was unplugged, when it was unplugged more codes were in pressent.

Did you disconnect the negative terminal to the battery when working on it? If you didn't, there is a chance the DME could be damaged. For temporary, you can pull the valve cover, turn the velvetronic to the left (max lift). It will start and run but you will get that constant error.

negative battery terminal was disconnected until I finished with the work, then I reconnected and coded injectors and battery, then tried to start it
