Picked up M3 yesterday and now a few minor problems (Not Major)

[m-i-l]

I had the brake issue too, and have had it seen to in a Service Centre - see New Model 3 brake issue for more info.

Congrats. Picked up my SR+ last week. Similar to you, I've had some issues. Rattingling rear passenger panel, lots of condensation in one of the brake lights on the boot and an audio issue where all sounds come out chopped (music and alert sounds). It's been in for about 7 hours so far on the audio issue with no resolution so I'm taking it back to Brooklands on Tuesday and getting a loaner until they sort it. I hope your bits get sorted soon!
