The vehicles will be visible and flagged in VMI as OPEN on April 5, 2024. Mercedes-Benz AG, the manufacturer of Mercedes-Benz vehicles, has determined that on certain MY 2023 C-Class, GLC, S-Class, and SL (206, 223, 232, and 254 platform) vehicles, the DRVU control unit does not correspond to current production specifications. As a result, an incorrect fault stored message may appear (e.g. U188D00 and U015400) in the instrument cluster, indicating a missing signal, when in fact such signal is not required at this time. MBUSA will conduct a service campaign. An authorized Mercedes-Benz dealer will update the SCN coding for the DRVU Control Unit.","document":{"url":"https://static.nhtsa.gov/odi/tsbs/2024/MC-10253697-0001.pdf","alternate_url":"https://static.nhtsa.gov/odi/tsbs/2024/MC-10253697-9999.pdf","confirmed":false},"url":"https://open.wenmarpro.com/bulletins/10253697","components":[{"id":"electrical","name":"Electrical system","parent":null}],"codes":["U0154","U188D"],"topics":[],"vehicles":[{"make":"MERCEDES-BENZ","model":"AMG C43","year_from":2023,"year_to":2023,"match":null,"vehicle_ids":[]},{"make":"MERCEDES-BENZ","model":"AMG C63 S","year_from":2023,"year_to":2023,"match":null,"vehicle_ids":[]},{"make":"MERCEDES-BENZ","model":"AMG C63 S E","year_from":2023,"year_to":2023,"match":null,"vehicle_ids":[]},{"make":"MERCEDES-BENZ","model":"AMG GLC43","year_from":2023,"year_to":2023,"match":null,"vehicle_ids":[]},{"make":"MERCEDES-BENZ","model":"AMG GLC63 S","year_from":2023,"year_to":2023,"match":null,"vehicle_ids":[]},{"make":"MERCEDES-BENZ","model":"AMG SL43","year_from":2023,"year_to":2023,"match":null,"vehicle_ids":[]},{"make":"MERCEDES-BENZ","model":"AMG SL55","year_from":2023,"year_to":2023,"match":null,"vehicle_ids":[]},{"make":"MERCEDES-BENZ","model":"AMG SL63","year_from":2023,"year_to":2023,"match":null,"vehicle_ids":[]},{"make":"MERCEDES-BENZ","model":"C 300","year_from":2023,"year_to":2023,"match":null,"vehicle_ids":[]},{"make":"MERCEDES-BENZ","model":"GLC 300","year_from":2023,"year_to":2023,"match":null,"vehicle_ids":[]},{"make":"MERCEDES-BENZ","model":"S 500","year_from":2023,"year_to":2023,"match":null,"vehicle_ids":[]},{"make":"MERCEDES-BENZ","model":"S 580","year_from":2023,"year_to":2023,"match":null,"vehicle_ids":[]},{"make":"MERCEDES-BENZ","model":"S 580 E","year_from":2023,"year_to":2023,"match":null,"vehicle_ids":[]},{"make":"MERCEDES-MAYBACH","model":"S 580 4MATIC","year_from":2023,"year_to":2023,"match":null,"vehicle_ids":[]},{"make":"MERCEDES-MAYBACH","model":"S 680","year_from":2023,"year_to":2023,"match":null,"vehicle_ids":[]}],"as_of":"2026-10-19","note":"A bulletin is a manufacturer's communication to its dealers, as NHTSA indexes it.
