If you want to do it in steps from least $ to most $, you can, but it's quiet a bit of work. Took me 8hrs to replace both (would be same time for either, since both tstat and pump have to come out for you to replace either).
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
