That's correct, but I was wondering if we reset the CBS ourselves after a DIY oil change if dealer knows we did
. They don't do it because the next time the system triggers a tranny and oil differential fluid change along with engine oil. Hmmmmm. They also should be done every 2 years regardless of miles (same as engine oil once a year), but BMW doesn't want to do that.
I just changed my oil with 4,500 miles on the clock because it's been a year since the 1,200-mile service, and was seriously thinking about resetting the CBS (I did reset it with the brake fluid change I did myself), so I could maybe have another tranny and diff oil changes before warranty runs out, but I'll do that myself too. If my car doesn't have a problem (knocking on wood), it probably won't see a dealer again under my ownership
