Hi All,
Need some help please so I can correctly diagnose my crank to start issue.
A few days ago, the car cranked for longer than usual on the way to the supermarket (2kms away). I assumed it's probably a battery issue because it's mid winter here in Victoria, Australia. On the way back from the supermarket, same thing ... car took a while to start then the engine seemed to run ok. about 200m into the drive back home the car stalled. Car had to be towed back home.
So I did some obvious checks - battery, camshaft, crankshaft, fuel pressure, etc. and it all seems fine. ISTA-D is throwing error 273C00 (Camshaft sensor, signal No signal). Like I mentioned, Camshaft sensor seemed ok as I checked for voltage and Hall effect (watching the signal wire drop from 5V to 0V as the sensor gets close to metal). I even replaced the Camshaft sensor with a working one, but no difference.
Anyway, I wanted to rule out the worst case scenario which is a timing chain issue in my book. So I removed the Camshaft sensor below.

I then looked to see if the flywheel is turning and unfortunately it's not (see video link below).
BMW F10 crank no start - timing chain?
From my understanding the starter motor should have engaged the flywheel to turn, so is there anything I can check before concluding this is a timing chain issue? Is it wishful thinking to believe it may be something else? The car has only done 150,000kms and is a 520d (Engine label is N47D20O1). Thanks in advance.
