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):","document":{"url":"https://static.nhtsa.gov/odi/tsbs/2023/MC-10244734-0001.pdf","alternate_url":"https://static.nhtsa.gov/odi/tsbs/2023/MC-10244734-9999.pdf","confirmed":false},"url":"https://open.wenmarpro.com/bulletins/10244734","components":[{"id":"structure-body","name":"Body and frame","parent":null}],"codes":[],"topics":[],"vehicles":[{"make":"MERCEDES-BENZ","model":"AMG GT 63","year_from":2019,"year_to":2020,"match":"base","vehicle_ids":["2019_mercedes-benz_amg-gt","2020_mercedes-benz_amg-gt"]},{"make":"MERCEDES-BENZ","model":"AMG GT43","year_from":2020,"year_to":2024,"match":"base","vehicle_ids":["2020_mercedes-benz_amg-gt","2021_mercedes-benz_amg-gt","2022_mercedes-benz_amg-gt","2023_mercedes-benz_amg-gt","2024_mercedes-benz_amg-gt"]},{"make":"MERCEDES-BENZ","model":"AMG GT53","year_from":2019,"year_to":2023,"match":"base","vehicle_ids":["2019_mercedes-benz_amg-gt","2020_mercedes-benz_amg-gt","2021_mercedes-benz_amg-gt","2022_mercedes-benz_amg-gt","2023_mercedes-benz_amg-gt"]},{"make":"MERCEDES-BENZ","model":"AMG GT63","year_from":2019,"year_to":2024,"match":"base","vehicle_ids":["2019_mercedes-benz_amg-gt","2020_mercedes-benz_amg-gt","2021_mercedes-benz_amg-gt","2022_mercedes-benz_amg-gt","2023_mercedes-benz_amg-gt","2024_mercedes-benz_amg-gt"]},{"make":"MERCEDES-BENZ","model":"AMG GT63 S","year_from":2022,"year_to":2023,"match":"base","vehicle_ids":["2022_mercedes-benz_amg-gt","2023_mercedes-benz_amg-gt"]},{"make":"MERCEDES-BENZ","model":"AMG GT63S","year_from":2019,"year_to":2021,"match":"base","vehicle_ids":["2019_mercedes-benz_amg-gt","2020_mercedes-benz_amg-gt","2021_mercedes-benz_amg-gt"]}],"as_of":"2026-10-19","note":"A bulletin is a manufacturer's communication to its dealers, as NHTSA indexes it.
