1122 – AL Flap BypassA Calibr. Drive Err
Cause
Corrective action
The ECU has detected a
calibration movement error at the
bypass flap on the A side (M52.1/
MA52.1). Cause: The teach-in
range (angle) of the calibration
movement is not plausible. The
teach-in angle does not lie
between the minimum and
maximum range.

1123 – AL Flap BypassB Calibr. Drive Err
Cause
Corrective action
The ECU has detected a
calibration movement error at the
bypass flap on the B side (M52.2/
MA52.2). Cause: The teach-in
range (angle) of the calibration
movement is not plausible. The
