You have to wonder... the engineers get to play around like this but then they use the "feature" to generate service calls. Get you in the shop and maybe try to sell other services.
Then they make almost incomprehensible changes to the regular service intervals. I have a friend that has a 2009 or 10 vintage 3 series and it has a 25k miles oil change interval using the long life synth. I think that came about due to the free routine maintenance service policy and them wanting to keep their costs low. Yeah, you will probably be fine for the usual time folks keep cars but what about the really long term? I always thought that 3k was too soon to change oil but no way I'd go 25k, no matter what BMW says. Just seems nuts to me....
Tip: sell it and buy American....believe me I made the mistake of a 2004 Mercedes even with 30k original mikes that car is a POC something major breaks about every other week. The older German cars are just complete crap, too much electronics for their own good and very expensive to fix...btw you will run into electronic repairs that you need the dealer to use their equipment to diag, some of it requires special scanners and tools
All cars have electronics these days, and all of them require using dealer-only gear to configure them. It's not unique to any brand. There's a pretty vibrant 3rd party market for interfaces and software for just about any make & model.
