1108 – AL Flap Bypass B Targetposition
Cause
Corrective action
The servomotor of the bypass flap
on the B side (M52.2/MA52.2)
has failed to reach its target
position within the set time.

1115 – AL Difference P0 P1 Intake Air L1
Cause
Corrective action
The differential pressure
measured at sensor B90 and the
ambient air pressure sensor
integrated in the ECU has violated
limit value 1. The intake air
differential pressure is too high.
1. Check air filter for dirt (plant).
2. Contact Service.
1116 – AL Difference P0 P1 Intake Air L2
Cause
Corrective action
The differential pressure
measured at sensor B90 and the
ambient air pressure sensor
integrated in the ECU has violated
limit value 2. The intake air
differential pressure is too high.
1. Check air filter for dirt (plant).
2. Contact Service.
1120 – AL Flap Egr A Calibration Drive Err
Cause
Corrective action
The ECU has detected a
calibration movement error at the
EGR shutoff flap on the A side
(M53.1/MA53.1). 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.

1121 – AL Flap Egr B Calibration Drive Err
Cause
Corrective action
The ECU has detected a
calibration movement error at the
EGR shutoff flap on the B side
(M53.2/MA53.2). 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.
