Greetings I'm new here and glad to be part of your group. I just received a recall notice in the mail for my 2021 GR Supra. They claim you could suddenly lose your braking assistance if you don't let them work on your car. They say it will take over 3 hours in the shop. Personally I had planned to change my own oil and never let the dealership get their hands on my car. I am assuming this will wipeout all my Bimmer Code hacks and possibly mess with the car's performance all around. Anyone had this done yet and did it effect any of your Bimmer Code hacks or mess with your custom tuning?
