Hi. Welcome to the wonderful world of BMW ownership and repair! I’ve been caring for my 2008 335xi since I bought it new. I’ve walnut blasted three times now. I also use the $8 remote starter switch connected to the starter motor. I disconnect the fuse for the low pressure fuel pump. But beforehand try starting to relieve pressure in the fuel rail to ensure the engine doesn’t turn over. Don’t worry about the code - you’ll clear it later. Then you’ll be good to go.
Good luck!
Good luck!
