By the way, Castrol 10w-40: MEETS API SN, SM, SL, SJ, ACEA A3, B3, and B4 but why isn’t it LL-01 approved? This oil meets two other criteria API SN and SM more than 0w-30 and 5w-40 and it is not LL01 approved or LL-98 approved, why?
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
