When performing a quick test, the following fault code is stored in Y3/14 ‑ Transmission control for 8‑speed dual‑clutch transmission (DKG): P24F100 The wake‑up line of the control unit has a short circuit to positive. Cause Possible signal timing between EZS control unit and Transmission Control Unit (DKG) Remedy As of 7/15/2026, new SCN coding is available for the EZS control unit. IPR will advise to open a TIPS case for EZS (N73), this is due to GLA models requiring support for SCN coding procedure. GLB (X247) and CLA (118) No TIPS case necessary. 1. SCN coding of EZS Control Unit 2. Clear all faults and perform extended road test with multiple drive cycles GLA (H247) Special function password required. 1. Verify if special procedure Central Locking ‑ Development Data is present in EZS (figure 1) 2. Submit a TIPS case to the Powertrain Inbox with the following information: ‑ Initial Quick Test w/ freeze frame data ‑ IPR Result ‑ DKG Control Unit Log ‑ EZS Control Unit Log ‑ Initial EEPROM data ‑ EZS special procedure menu If the vehicle has had this LI performed and P24F100 has returned, please submit a TIPS case to the Powertrain Inbox.","document":{"url":"https://static.nhtsa.gov/odi/tsbs/2026/MC-11037210-0001.pdf","alternate_url":"https://static.nhtsa.gov/odi/tsbs/2026/MC-11037210-9999.pdf","confirmed":false},"url":"https://open.wenmarpro.com/bulletins/11037210","components":[{"id":"electrical","name":"Electrical system","parent":null}],"codes":["P24F1"],"topics":[],"vehicles":[{"make":"MERCEDES-BENZ","model":"AMG CLA35","year_from":2020,"year_to":2024,"match":null,"vehicle_ids":[]},{"make":"MERCEDES-BENZ","model":"AMG CLA35 4MATIC","year_from":2020,"year_to":2020,"match":null,"vehicle_ids":[]},{"make":"MERCEDES-BENZ","model":"AMG CLA35 4MATIC","year_from":2025,"year_to":2026,"match":null,"vehicle_ids":[]},{"make":"MERCEDES-BENZ","model":"AMG CLA45","year_from":2020,"year_to":2023,"match":null,"vehicle_ids":[]},{"make":"MERCEDES-BENZ","model":"AMG CLA45 4MATIC","year_from":2020,"year_to":2020,"match":null,"vehicle_ids":[]},{"make":"MERCEDES-BENZ","model":"AMG CLA45S 4MATIC","year_from":2025,"year_to":2025,"match":null,"vehicle_ids":[]},{"make":"MERCEDES-BENZ","model":"AMG CLA45S 4MATIC+","year_from":2026,"year_to":2026,"match":null,"vehicle_ids":[]},{"make":"MERCEDES-BENZ","model":"AMG GLA 35","year_from":2024,"year_to":2025,"match":null,"vehicle_ids":[]},{"make":"MERCEDES-BENZ","model":"AMG GLA 35 4MATIC","year_from":2024,"year_to":2024,"match":null,"vehicle_ids":[]},{"make":"MERCEDES-BENZ","model":"AMG GLA 35 4MATIC","year_from":2026,"year_to":2026,"match":null,"vehicle_ids":[]},{"make":"MERCEDES-BENZ","model":"AMG GLA35","year_from":2021,"year_to":2023,"match":null,"vehicle_ids":[]},{"make":"MERCEDES-BENZ","model":"AMG GLA45","year_from":2021,"year_to":2023,"match":null,"vehicle_ids":[]},{"make":"MERCEDES-BENZ","model":"AMG GLB35","year_from":2021,"year_to":2025,"match":null,"vehicle_ids":[]},{"make":"MERCEDES-BENZ","model":"AMG GLB35 4MATIC","year_from":2026,"year_to":2026,"match":null,"vehicle_ids":[]},{"make":"MERCEDES-BENZ","model":"CLA 250","year_from":2020,"year_to":2026,"match":null,"vehicle_ids":[]},{"make":"MERCEDES-BENZ","model":"CLA 250 4MATIC","year_from":2020,"year_to":2026,"match":null,"vehicle_ids":[]},{"make":"MERCEDES-BENZ","model":"GLA 250","year_from":2021,"year_to":2026,"match":null,"vehicle_ids":[]},{"make":"MERCEDES-BENZ","model":"GLA 250 4MATIC","year_from":2021,"year_to":2026,"match":null,"vehicle_ids":[]},{"make":"MERCEDES-BENZ","model":"GLB 250","year_from":2020,"year_to":2026,"match":null,"vehicle_ids":[]},{"make":"MERCEDES-BENZ","model":"GLB 250 4MATIC","year_from":2020,"year_to":2026,"match":null,"vehicle_ids":[]}],"as_of":"2026-10-19","note":"A bulletin is a manufacturer's communication to its dealers, as NHTSA indexes it.
