Incorrect data were received. C156F00 - The signal values of the level sensors are implausible. Cause Physical layer wiring to the level control sensors B22/X. Remedy Check A108/2 and A108/3 for freeze frame data section \"ZF_error_handler\". The text will provide a good place to start. Example: \"SPC_FEHLER_VehLvl_Stat_HP_AMG_AR2_SNA_VehLvl_RR_V2_AMG\" indicates the Right Rear may have initiated the DTC. See attached picture for reference. Is concern reproducible? If so, watch actual values in Xentry and see which sensor is setting the implausible value. Use Hioki to measure wiring to all four level sensors from N51/8. Use above DTC freeze frame data to physically inspect specific wiring as mentioned in the freeze frame data above. Check all level sensors for damage, correct mounting, level sensors bound or not moving, etc... If vehicle exhibits concern after all of the above is completed, please open a TIPS case to the Body, Chassis, Entertainment Inbox.","document":{"url":"https://static.nhtsa.gov/odi/tsbs/2026/MC-11028814-0001.pdf","alternate_url":"https://static.nhtsa.gov/odi/tsbs/2026/MC-11028814-9999.pdf","confirmed":false},"url":"https://open.wenmarpro.com/bulletins/11028814","components":[{"id":"suspension","name":"Suspension","parent":null}],"codes":["C156F","U0132"],"topics":[],"vehicles":[{"make":"MERCEDES-BENZ","model":"AMG EQE SUV 4MATIC","year_from":2024,"year_to":2025,"match":null,"vehicle_ids":[]},{"make":"MERCEDES-BENZ","model":"AMG GLE53","year_from":2021,"year_to":2022,"match":null,"vehicle_ids":[]},{"make":"MERCEDES-BENZ","model":"AMG GLE53 4MATIC+","year_from":2023,"year_to":2025,"match":null,"vehicle_ids":[]},{"make":"MERCEDES-BENZ","model":"AMG GLE53 4MATIC+ COUPE","year_from":2025,"year_to":2025,"match":null,"vehicle_ids":[]},{"make":"MERCEDES-BENZ","model":"AMG GLE63","year_from":2021,"year_to":2024,"match":null,"vehicle_ids":[]},{"make":"MERCEDES-BENZ","model":"AMG GLE63 S","year_from":2021,"year_to":2022,"match":null,"vehicle_ids":[]},{"make":"MERCEDES-BENZ","model":"AMG GLE63 S 4MATIC+","year_from":2023,"year_to":2024,"match":null,"vehicle_ids":[]},{"make":"MERCEDES-BENZ","model":"AMG GLE63 S 4MATIC+ COUPE","year_from":2025,"year_to":2025,"match":null,"vehicle_ids":[]},{"make":"MERCEDES-BENZ","model":"AMG GLS63","year_from":2020,"year_to":2022,"match":null,"vehicle_ids":[]},{"make":"MERCEDES-BENZ","model":"AMG GLS63","year_from":2026,"year_to":2026,"match":null,"vehicle_ids":[]},{"make":"MERCEDES-BENZ","model":"AMG GLS63 4MATIC+","year_from":2023,"year_to":2025,"match":null,"vehicle_ids":[]},{"make":"MERCEDES-BENZ","model":"AMG S 63 E 4MATIC+","year_from":2023,"year_to":2025,"match":null,"vehicle_ids":[]}],"as_of":"2026-10-19","note":"A bulletin is a manufacturer's communication to its dealers, as NHTSA indexes it.
