X5 BMW Service Recommendation Changes?

How are you comparing highway driving service intervals to in-town driving service intervals in your example? Are you comparing the 9000 mile interval to previous experience with a gasoline engine?

It seems to me more like the CBS thinks the diesel engine needs oil changes more frequently than the gasoline engine models. If so, and given the high mileage diesel owners outside North America seem to get between oil changes, it may be related to North American diesel fuel quality.

Let us know if you find out what the vehicle service light trigger is, as my 535 is also calling for a vehicle service at other than oil change intervals.

No, I am comparing it to what other people have been reporting on this message board. Since my in-town driving is almost zero, I am assuming most other people have more in-town driving than I do. By average of an oil change in less than 9,000 miles on average also seems to place my vehicle at or near the bottom of oil change intervals. Hence my comment "it is beginning to look like the CBS thinks high-speed highway driving is harder on the diesel oil than in-town stop-and-go driving," which is quite a distance from being a definitive claim or conclusion.

Got my 8000 mile/annual service today. Noticed that the telephone number calling display is different since they programmed it (8:30 to 10:30am for oil/filter, def (?4 gallons) and wipers then 10:30 to 4pm for programming "upgrades" and two campaigns...)

Did not notice any difference other than the telephone display on the iDrive (improved) and that the brakes were better. Perhaps brakes just better than the X3 loaner (2010 MY) . All my contacts and destinations were preserved, fyi.
