Hi all. I'm new to this so really hope someone can point me in the right direction. I have an '07 BMW 530d SE Auto with 85k on it. Over the past few months I've noticed random odd gearbox action like sometimes it won't change from 2nd to 3rd until 2500 RPM or other odd bits but most of the time it's fine. However, it now won't select 1st gear by itself when I pull to a stop.
So, I'm driving along and all is good. I come to a stop at lights or whatever and go to pull away and it pulls away in second. If I'm trying to pull away up a steep hill it may then suddenly lurch into first before changing back and then carrying on pretty much as normal.
If I put the gear lever over to Sport it's the same. But if I drive in manual, and manually change to 1st when I stop (because it still won't do it on it's own) then it pulls away nicely in 1st and I can manually change through the gears without problem.
Has anyone come across this before or give me some suggestions as to whether it's likely to be something simple. Any advice would be really appreciated. Many thanks
