Over temp reported by actuator for panel/floor (M57).
Check that the panel/floor flap can move freely, if no fault is found, replace the panel/floor flap motor. This unit is connected to the climate control system via a LIN-bus. If one of the units on the LIN-bus is faulty it can affect the other units further down the same communication line. The LIN-units are split into three lines from C8061, one to the sun sensor, one to the humidity sensor via C24, and one to multiple units via C8046. From C8046 the units are arranged: air intake/recirc control motor, air dist/defrost. motor, mix air/temp flap motor, panel/floor flap dist. motor, 2nd recirc/AQS motor and AQS-sensor.
What you'll see
No driver-visible symptom recorded.
System reaction
The panel/floor flap may not function.
Diagnostic depth
The climate control system (E17) has detected the actuator reports an error.
