Thank you for this form.

I have a MY2006 Z4M. 45,000KM. Owned the car since 2008. When I purchased the car the check engine light was on. Took it to BMW for inspection and all was good, no issues. The light reset. 30k later the engine stopped working, Service says the Cams are not moving, Replaced Vanos, Bottom of engine is good. Top of engine is not working. From what I (not mechanical guy) understood, a screw broke off and camshaft prevention sensor error was noted and replaced but the cams were not moving hence the error code. Tech says the engine needs to be replaced. Any suggestions?
 
So if the crankshaft is turning and the camshafts are not turning the drive between the two is broken ie the cam chain, the subsequent damage is bent broken valves you would be looking at a very big repair bill.

I or we need a bit more info or you need to get someone who knows what they are doing to look if you keep turning it over you are just smashing the internals up more and more if the top and bottom half is no longer connected.
