It is very possible that the driving style has something to do with that specific problem.
When I bought my X, it was driven by the garage owner during the time it was for sale (about 3 weeks). According the the fuel consumption computer, he had a heavy foot. But the tranny was working flawlessly.
Since I own the X, (3 months) I meanly use it to go to work in traffic and on highways, so, only smooth driving. Maybe I should try to drive it in a more sporty way to see if it changes something.
What bugs me the most, is not the fact the the transmission is holding the 2nd gear a long time before engaging the 1st, but it's the delay in the downshifting (2nd-1st). That delay is like a neutral that last a fraction of a second, but causes a problem if I happen to reaccelerate during that time. (high rev, then bang).
I think I will try the oil change.
I also read on a French (France) forum dedicated to X serie, and they are in a big percentage in favor of changing the oil in our trucks, compared to here where it is like 50-50.
Over there, they have access to ZF shops, and the ZF techs suggest to change the oil in their trannies, even if BMW says no.
Hummm, so many conflicting opinions....
