Mercedes-Benz bulletin LI07_02-N-079573_2_en
Mercedes-Benz filed this with NHTSA as a service bulletin dated Aug 5, 2026, received Sep 3, 2026, about the fuel/propulsion system. It names 6 model years (2020–2026). A service bulletin is not a safety recall: it is the manufacturer telling its dealers how to diagnose or repair a condition, and whether the work is paid for depends on the warranty in force. Quoting the number at a service desk can save a diagnosis.
What the bulletin says
Source: NHTSA's summary of the manufacturer's communicationOil Leak at Crankcase Near the High-pressure Fuel Pump OM654 Complaint Visible oil leak at the crankcase near the mounting area of the high‑pressure fuel pump on OM654 engines. 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.

The summary is NHTSA’s abstract of the document, as filed under 49 CFR 579.5. One communication is usually filed as several documents — the bulletin, a dealer notice, an owner letter — and the number on any of them finds this page. A PDF link is shown only once NHTSA’s own server has been seen to serve that document; the rest are checked over the following nights. Quote the number at a service desk; it is what the dealer’s system is keyed on.

Common questions
Source: NHTSA, 49 CFR 579.5Is Mercedes-Benz LI07_02-N-079573_2_en a recall?
No. A service bulletin is a manufacturer communication filed with NHTSA under 49 CFR 579.5; a safety recall carries an NHTSA campaign number (two digits, a letter, six digits) and a federal duty to repair for free. Check the vehicle’s recalls by VIN at nhtsa.gov/recalls, or on its page here.
Is the LI07_02-N-079573_2_en repair free?
Not automatically. A service bulletin describes how to diagnose or repair a condition; who pays depends on the warranty in force, any extension, and the dealer. Quoting the number can save a diagnosis either way.
Which vehicles does LI07_02-N-079573_2_en cover?
The manufacturer filed it against 6 model years: 2025 Mercedes-Benz Sprinter, 2024 Mercedes-Benz Sprinter, 2023 Mercedes-Benz Sprinter, 2020 Mercedes-Benz Sprinter, 2026 Mercedes-Benz Sprinter 2500, 2026 Mercedes-Benz Sprinter 3500. Whether one particular vehicle is affected is a matter of its VIN and its build, not its model year alone.
