Service campaign 2026050008

A bulletin is a manufacturer's communication to its dealers, as NHTSA indexes it. The summary is NHTSA's. The document is the manufacturer's: read it at NHTSA. A bulletin is not a recall, and listing a model year does not mean every vehicle of it is concerned.

LI54_10-N-080879_1_en	2026-09-03. Service bulletin. AC and DC Charging inoperative with no failure codes in the relevant control units Complaint AC and DC charging are not possible. The white LED on the charging inlet completely goes OFF after plugging in the charging cable. Cause Control pilot (CP) circuit in DCB (N24/6: Charger (DC)) might be not functioning due to electrical overstress from EVSE (Electric Vehicle Supply Equipment \| Charging Station). Remedy Refer to the charging cable actual values in DCB (N24/6).
LI47-70-N-080294	2026-04-02. Service bulletin. eSprinter model series 907: Intermittent no-start condition Complaint Intermittent no-start condition; partial restart without "Ready" status in display. Concern may be rectified after bus idle and/or circuit 30 deep reset. Cause As a result of inaccuracies in Battery Management System measurements, the BMS may record the following fault codes: P0ABD00 - Battery voltage sensor A in the hybrid/high-voltage battery module has a short circuit to positive. P0B171C - Battery voltage sensor B in the hybrid/high-voltage battery module has a short circuit to positive. The vol-tage value is outside the permissible range P181D12 - The reference voltage at output A has exceeded the limit value. There is a short circuit to positive Remedy Perform a software update of control unit G1/9 - battery management system (BMS) (BMS907)
LI47.70-N-079913	2025-12-03. Service bulletin. Vehicle not starting after DC charging Complaint Vehicle will not start after DC charging Warning in the instrument cluster related to High-voltage on board electrical system The following fault codes related to stuck contactor can be found in the High Voltage Control units : PTCU - N127 (Powertrain control unit) • P154900 - There is a warning due to overcurrent in the charging system of the high-voltage electric circuit. • P154A00 - There is a warning due to a detected crash event at standstill. • P154B00 - There is a warning due to a stuck contactor. DCB223 - N116/5 (Direct current charge connection unit) • P0E8929 - The input current of the on-board DC charging connection unit is too high. There is an invalid signal. • P2BC500 - The contact ''Positive terminal'' of the contactor in the on-board DC current charge-connection unit is jammed closed • P2BCC00 - The contact ''Negative terminal'' of the contactor in the on-board DC current charge-connection unit is jammed closed. Remedy • Check for a new software availability for DCCU (N24/6 - Direct Current Charge connection Unit). If a new software is available, update the software first. • Reset contactor fault through special procedure without password. ( N24/6 >> Special Procedure >> Resetting of contactor fault.)
V3EAUFLAD	2025-03-04. Service campaign. Mercedes-Benz AG, the manufacturer of Mercedes-Benz eSprinter vans, has determined that a new NACS adapter informational label is required for the use of an approved Mercedes-Benz DC Fast Charging Adapter. An authorized Mercedes-Benz Sprinter dealer will affix the information label in the area of the charging socket.
LI54.10-N-078161	2024-09-05. Service bulletin. Complaint • "Unable to calibrate battery, see Operator’s Manual." • "Calibrate battery to ensure max. range is achieved, start charging process up to 100%". Remedy: Standard calibration is necessary. • "Calibrate battery to ensure max. range is achieved, charging time extension: start XX min AC charging up to 100%". Remedy: Special calibration is necessary. • "Battery calibration necessary, start AC charging up to 100% for state of charge: max. 15%; outside temperature: min. 15 °C". Remedy: Special calibration is necessary. Cause The eSprinter 2.0 (model series 907) is equipped with a high-voltage battery with LFP (lithium iron phosphate) technology. This stands out in comparison to the NMC technology (lithium nickel manganese cobalt oxide) through its particularly long service life but it has to be calibrated regularly to achieve a precise SOC and range forecast. Ideally, along with the automatic calibration, a special calibration should also be conducted 2 times a year. Remedy Automatic/standard calibration of high-voltage battery Conducted automatically during every charging process up to 100% and it does not need to be triggered. Requirements for special and manual calibration: • The driver can wait for the calibration-related extended charging time to be completed. • The outside temperature is at least 15 °C. • The state of charge is less than 15%. • High-voltage battery charged up to 100%. • With automatic calibration the high-voltage battery has to be charged with AC. With manual calibration, DC charging is also an option. • Check if a departure time is preset that is reached before the end of the charging time (including charging time extension) and, where possible, deactivate it. • Check if the maximum state of charge is set to 100%. • Check if, during calibration, an electrical consumer was used or if the power supply was switched on. • Where possible, avoid any strong cooling of the vehicle or re-arrange the time of the calibration until the weather conditions are more favorable.
