I think it's just something to do with the fact that N53/N54/N55 utilize direct injection, while the N52 does not. They said they only give _28i models the injector flush service, though it's not a "routine maintenance" type thing so it's always extra. They didn't really tell me anything else beyond that, but I guess it makes sense to me. I haven't thought much into it, though. And I'm pretty sure the BMW brand injector cleaner IS the Chevron cleaner, with a roundel on the bottle and a price markup to match
