Quick answer

Rear spoiler sporadically remains in opened position or does not extend and a fault message appears in the instrument cluster. The rear spoiler can then no longer be retracted manually using the button. The function of the rear spoiler is re-established after an ignition reset and the fault message is no longer present in the instrument cluster. Possible causes: Coding of the AMG DRIVE UNIT for recognition of Hall sensor when retracting rear spoiler. Hardware tolerances / hardware wear If new software for the AMG DRIVE UNIT is available, carry out the software update. If the vehicle already has the most current version of the AMG DRIVE UNIT software installed, conduct SCN coding of the AMG DRIVE UNIT. Then check the currently learned actual values under the path "DRVU -> Actual values -> Rear wing sensor system" (print AV screen prior to completing initialization -- if necessary):

What this bulletin may mean before buying

Treat this as service research, not a verdict on one car. Before you buy, compare this communication with official recall campaigns, model-level owner complaint patterns, and the exact vehicle’s VIN-decoded specifications. A bulletin can help you ask a seller or dealer sharper questions about software updates, known repairs, warranty extensions and service history.

How should a used-car buyer use this bulletin?

Use it as a research signal. Compare it with recalls, owner complaints, service records, a VIN report and an independent inspection before buying.
