The rear spoiler control module has an electrical motor and it is located in the rear lid behind the central lock.

Malfunctions which can be attributed to a temporary open circuit in the wiring or a loose contact will also be stored. These malfunctions will be displayed as sporadic DTCs (/SP).
After the ignition is switched on, the rear spoiler warning lamp lights up for about 4 seconds and then goes out again. If the lamp remains on, it means that the rear spoiler or other component is electronically blocked.

NOTE: During the rear spoiler control module self-adaptation the "pinch protection" function is inactive.
