What owners reported
Source: NHTSA complaint databaseOwners of the 7 model years this bulletin names have filed 389 complaints with NHTSA since 2015. 9 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 LI4700N069565 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 LI4700N069565 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.
Which vehicles does LI4700N069565 cover?
The manufacturer filed it against 7 model years: 2025 Mercedes-Benz Sprinter, 2024 Mercedes-Benz Sprinter, 2023 Mercedes-Benz Sprinter, 2022 Mercedes-Benz Sprinter, 2021 Mercedes-Benz Sprinter, 2020 Mercedes-Benz Sprinter and more. Whether one particular vehicle is affected is a matter of its VIN and its build, not its model year alone.
