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 5 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.

Read by machine from the document NHTSA serves (4 pages), read Sep 30, 2026. A part number is shown only where it matches Mercedes-Benz’s own catalogue shape, an operation only with its code and time, and a description only where the reader got it whole; anything it could not settle is left out, and the PDF is the record. Times are the manufacturer’s warranty allowances, not a quote. Listings and prices on eBay Motors are the seller’s.
Affiliate disclosure: some links on this page are affiliate links. If you request a quote or buy through them we may earn a commission at no extra cost to you. Nothing on this page changes because of it.
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.

What owners reported
Source: NHTSA complaint databaseOwners of the 5 model years this bulletin names have filed 161 complaints with NHTSA since 2015. 5 of them name Fuel/Propulsion System — the same broad component group this bulletin is filed under. NHTSA groups complaints coarsely, so that means the same area of the vehicle, not necessarily the same fault.
Occasionally, the idle speed of the engine will drop to 400 rpm. When this happens, the vehicle does not respond to throttle input. If it happens in a parking lot, you can shift into park and coax the rpm higher, then shift to drive and move 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. Every Mercedes-Benz warranty extension on file lists the ones Mercedes-Benz has filed.
