The joys of running a ~ 13year old 200k+ mile car - regardless of what it is - although it will be interesting to see if you find similar niggly issues cropping up with your new steed, unlikely you'd hope I'm sure but equally, given it's complexity over the e39, maybe, perhaps to be expected....?
The difference is I don't care if the F10 breaks down because I simply call BMW Emergency Service who will come and fetch it and sort the mess out

Whereas niggly issues on the E39 can now be treated as an enjoyable hobby
