2018 m550i drivetrain malfunction: boost pressure too high
Did anyone with a bootmod3 stage 1 tune n63tu2 get a drivetrain malfunction error showing boost pressure is too high. (Error code: 120208) I just installed a bootmod3 tune on my 2018 m550i and it throws this error every time I push the pedal to the floor. Is it over boosting from the tune and the tune didn’t adjust the pressure sensor to detect higher pressure ratings? Or could it be something else? I contacted PTF to see what they say, hopefully just needs a fix in the tune.
