Cause: The shaft seal (radial sealing ring) at the high-pressure fuel pump is not leak-tight, resulting in external oil leakage. Remedy: Install new high-pressure pump together with design-optimized sealing ring. 1. Replace the high-pressure fuel pump. 2. Discard the 2.5 mm O-ring included with the new pump. 3. Install the updated 2.6 mm O-ring (P/N: A0009973819). 4. Verify the repair using crack detection spray (P/N: A0009890359) around the pump mounting area. 5. If the leak reappears, submit a TIPS case to the Powertrain inbox with reference photos.","document":{"url":"https://static.nhtsa.gov/odi/tsbs/2025/MC-11021169-0001.pdf","alternate_url":"https://static.nhtsa.gov/odi/tsbs/2025/MC-11021169-9999.pdf","confirmed":false},"url":"https://open.wenmarpro.com/bulletins/11021169","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":2024,"match":"base","vehicle_ids":["2023_mercedes-benz_sprinter","2024_mercedes-benz_sprinter"]},{"make":"MERCEDES-BENZ","model":"SPRINTER 2500","year_from":2023,"year_to":2024,"match":"base","vehicle_ids":["2023_mercedes-benz_sprinter","2024_mercedes-benz_sprinter"]},{"make":"MERCEDES-BENZ","model":"SPRINTER 3500","year_from":2023,"year_to":2024,"match":"base","vehicle_ids":["2023_mercedes-benz_sprinter","2024_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.
