Just two notes for other owners/users of BMW´s:

1. At around 103kkms one out of two pre-cat o2 sensors died (my shitty slot-eyed diag could not recognise which one), replaced them both, but regrettably bought Delphis (upon VIN, of course) which resulted in sporadically, but re-occuring faults 2C9C, 2C3F and 2C3B. Only too late I came across a post somewhere "BMW´s DMEs REALLY DO work faultlessly with O2 sensors from Bosch ONLY" which proven to be very true to the last letter so far.
Btw, 100+ kkms seems to me OK. Wear part.

2. Should there is anyone who dislikes (= do not use it at all) the navigation and its display opening at each start-up and/or a reverse being geared-in. The fuse 76 "off" in the fusebox (btw, not quite easily accessible / hidden in dashboad) seems to be quite elegant solution to that. The navi/display completely dead/off, but no warnings/emblems on dashboard and reverse proximity sensors still running/beeping.
