Cause The injector hold-down may fracture due to material-related factors, allowing the injector to lift from its seat and resulting in combustion gas leakage past the sealing interface. Remedy Carry out repair measures in accordance with the extent of damage determined during inspection. Replace only tho-se components identified as faulty or compromised by the failure, including the fuel injector, sealing ring, injector hold-down, hold-down bolt, high-pressure fuel line(s), and, if required, the fuel distributor (rail). All work involving fuel injector removal and installation must be carried out in accordance with WIS document AR07.16-D-1020TSM. Particular attention must be given to the proper preparation of the injector bore and sealing in-terface. All carbon deposits, combustion residue, and surface contamination must be fully removed to ensure correct injector seating and sealing integrity, thereby preventing combustion gas blow-by and repeat failure.","document":{"url":"https://static.nhtsa.gov/odi/tsbs/2026/MC-11034406-0001.pdf","alternate_url":"https://static.nhtsa.gov/odi/tsbs/2026/MC-11034406-9999.pdf","confirmed":false},"url":"https://open.wenmarpro.com/bulletins/11034406","components":[{"id":"engine","name":"Engine","parent":null}],"codes":[],"topics":[],"vehicles":[{"make":"FREIGHTLINER","model":"SPRINTER 1500","year_from":2023,"year_to":2024,"match":"base","vehicle_ids":["2023_freightliner_sprinter","2024_freightliner_sprinter"]},{"make":"FREIGHTLINER","model":"SPRINTER 2500","year_from":2023,"year_to":2024,"match":"base","vehicle_ids":["2023_freightliner_sprinter","2024_freightliner_sprinter"]},{"make":"FREIGHTLINER","model":"SPRINTER 3500","year_from":2023,"year_to":2024,"match":"base","vehicle_ids":["2023_freightliner_sprinter","2024_freightliner_sprinter"]},{"make":"FREIGHTLINER","model":"SPRINTER 4500","year_from":2023,"year_to":2024,"match":"base","vehicle_ids":["2023_freightliner_sprinter","2024_freightliner_sprinter"]},{"make":"MERCEDES-BENZ","model":"SPRINTER 1500","year_from":2023,"year_to":2025,"match":"base","vehicle_ids":["2023_mercedes-benz_sprinter","2024_mercedes-benz_sprinter","2025_mercedes-benz_sprinter"]},{"make":"MERCEDES-BENZ","model":"SPRINTER 2500","year_from":2023,"year_to":2025,"match":"base","vehicle_ids":["2023_mercedes-benz_sprinter","2024_mercedes-benz_sprinter","2025_mercedes-benz_sprinter"]},{"make":"MERCEDES-BENZ","model":"SPRINTER 3500","year_from":2023,"year_to":2025,"match":"base","vehicle_ids":["2023_mercedes-benz_sprinter","2024_mercedes-benz_sprinter","2025_mercedes-benz_sprinter"]},{"make":"MERCEDES-BENZ","model":"SPRINTER 4500","year_from":2023,"year_to":2024,"match":"base","vehicle_ids":["2023_mercedes-benz_sprinter","2024_mercedes-benz_sprinter"]}],"as_of":"2026-10-19","note":"A bulletin is a manufacturer's communication to its dealers, as NHTSA indexes it.
