Unfortunately get ready for the endless N63 engine nightmare. I finally got rid of our last one which we went through 2 used 2014 550's. Both had 79k and 72k miles on them. Constant pita! Replaced fuel pumps, software upgrades, new battery, but NO CODE CAME UP WHERE BMW would replace under extended warranty which is complete bs. My Indy ran the codes and it pointed to the right front fp. Never knew this car had 3 fuel pumps. Always had the Drivetrain Malfunction pop up. The fuel injectors are another huge issue with this car. People as you know have had BMW replace the engine only if you waste half your life going through the continual process to have them finally throw on the towel and get lucky with them to say YES. It's a horrible experience for just owning a car. It's inexcusable actually. OP get ready for the roller coaster ride of back and forth to the dealer. Life is too short to for such a hassle to fix a car. Good luck!!
