what is the service interval for 535i (2010 year & 2011 model) on 2010 BMW 535i

frequency I understand is 25000 but dealer is insisting every 12000 kms. vehicle usage is appx 260 kms per week

If you are asking about oil and filter change i suggest every 4k miles. Regardless of other recommendations!
I may be wrong.
