What code is it throwing? Go to Autozone and have them check it for free. You really should invest in a peake research tool, see my sig.. Edit: Since your car doesn't start get the peake tool.

If I had to guess, intake camshaft sensor.

By the way, you can't tell if a sensor is bad just by looking at it.
If no codes are being thrown use Chevron Techron fuel injector cleaner (concentrate). It solves rpm fluctuating upon cold start-up. Also, for most BMW problems start off by scanning your car with the Peake Research Tool. It contains the actual BMW codes. If you want to register a newly installed battery for free (just buy a $10 cable) and google/download BMWLogger
