I've only done 500 miles so far and just have a couple of issues:
1. Rattling from the passenger door trim. I called in to the local dealer and they said it's probably the wiring loom hitting the back of the plastic - it's booked in for a fix.
2. My humorous wake word keeps disappearing so I have to resort to the rather boring "Hello BMW".
Apart from that, very happy. Obviously I'm still running in so keeping the revs well down but it still goes like a rocket. Can't wait to see what redlining in Sport Plus does
