2022 M340i xDrive Check Engine Light
Check engine light came on today. Trying to figure out what the issue is bimmerlink came back with FF21B2: Unknown error
Car has 1200ish miles, nothing out of ordinary. I've got an appointment with the dealer but if anyone has any idea what that error is let me know. Thanks |

An oxygen sensor? Loose gas cap. Or some emission thing. All warranty covered

Dealer can't get to me till the 13th. Any thoughts on if it's okay to drive? The navigation car status screen shows everything green and there is literally nothing it shows related to the check engine light. When the light first did come on the car showed a drivetrain malfunction. But said it was fine to drive. Seems so weird to have a check engine light with no like status or direction as to needing to do something.

Tighten gas cap and reset light with bimmerlink. It might not come back on.
