Also, don't put a lot of faith in what dealers state. They misinform customers and sometimes make shoddy repairs. I base my statement from personal experience and by reading horror stories on this forum.
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
