Great thread! I've been following along since I recently purchased a 2013 Alpina B7 w/ 39k miles on it. Your car is looking great! Luckily, the only code my car is throwing is for the driver's comfort access door handle. I've ordered a used one from eBay to see if that will fix it.
I also should stop following your thread because you have me thinking about blue brake calipers. :joy:
Question on the radio: did you happen to see the manufacturer or the part number? Zooming in on your pic is blurry for me. I've been thinking of upgrading the existing entertainment system with the P2000 from Mr. 12Volt or whatever works with our cars:

Thanks!
