Guys,

I have 10K on the car and it still tells me everytime i start the car that i should service in 6K!!! it supposed to be serviced at 12K why doesn't the computer gives me the right thing

Is scheduled maintenance included (paid for by BMW) in Saudi Arabia? If so, you have your answer. They do as little as possible. If you drive 10K miles in less time than they suspect, they add more miles. Oil services are calculated by miles and time intervals.

If you pay for maintenance in SA, then just ignore it and get an oil change at 12K or so.

i'm at 16k and haven't serviced it yet.

There was a recent rant (maybe on this forum - - can’t remember) about the lack of a dipstick on some of the latest BMW engines. Actually, you should be happy. That is an indication that the motor is equipped with a neat device designed by Bosch called an oil condition monitor. It constantly measures oil level and the dielectric properties of the oil. As the oil (very, very slowly) ages, picks up wear metals, acids, fuel dilution, and oxidizes, the conductivity or dielectric properties of the oil changes. That’s where all that field testing comes in. BMW can correlate the electrical values measured at any one time to the general condition of the oil and adjust the oil change interval if the oil is in danger of becoming unserviceable. Bosch’s latest oil condition monitor even has a little transducer that bounces sound waves off the oil to measure changes in viscosity. What more do you want?

If you trust the engineers and their science, then this is a result of how you've driven the car. If the car has not been driven hard and the oil is still doing it's job, there's no need to replace it yet.

On the other hand, is the people who say this is just their way of making them do as little work on your car for free as possible. There's truth on both sides of the coin.
