[DEJMIEN]

My guess is that it is a bdc problem, specifically someone may have used autohex early on to reset the mileage. I have exactly the same thing in two cars after replacing and reset mileage on the bdc/fem. Everything works until you disconnect the battery, mileage simply jumps between current and old one, and also servises are not available as well. The problem is that autohex permanently cuts off the synchronisation between bdc and kombi. Even an update does not help. And autohex support doesn't know what the problem is or how to even fix it. The quickest way to fix this is to reset the mileage in the bdc, for a while until you disconnect the battery. You can also reset the mileage on the kombi but I bet you'll get 000 after all and that will only confirm my theory. Next time I will try to use acdp or something else but not autohex.
