Cause Oil leakage near the high‑pressure fuel pump may result from insufficient sealing performance of the jump shaft seal and/or reduced sealing effectiveness at the interface between the high‑pressure fuel pump and crankcase. Relative movement of the high‑pressure fuel pump within the crankcase bore may reduce sealing effectiveness at the pump‑to‑crankcase interface and promote oil migration during engine operation. Remedy Install a new high‑pressure fuel pump together with the design‑optimized sealing ring.","document":{"url":"https://static.nhtsa.gov/odi/tsbs/2026/MC-11036846-0001.pdf","alternate_url":"https://static.nhtsa.gov/odi/tsbs/2026/MC-11036846-9999.pdf","confirmed":false},"url":"https://open.wenmarpro.com/bulletins/11036846","components":[{"id":"fuel-system","name":"Fuel system","parent":null}],"codes":[],"topics":[],"vehicles":[{"make":"FREIGHTLINER","model":"SPRINTER (VS30)","year_from":2020,"year_to":2020,"match":"base","vehicle_ids":["2020_freightliner_sprinter"]},{"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 (VS30)","year_from":2020,"year_to":2020,"match":"base","vehicle_ids":["2020_mercedes-benz_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":2026,"match":"base","vehicle_ids":["2023_mercedes-benz_sprinter","2024_mercedes-benz_sprinter","2025_mercedes-benz_sprinter","2026_mercedes-benz_sprinter"]},{"make":"MERCEDES-BENZ","model":"SPRINTER 3500","year_from":2023,"year_to":2026,"match":"base","vehicle_ids":["2023_mercedes-benz_sprinter","2024_mercedes-benz_sprinter","2025_mercedes-benz_sprinter","2026_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.
