20250800082025-10-07. Service campaign. ELECTRICAL SYSTEM. MBAG has determined the software of the control unit for the anti-theft warning system does not correspond to the current production configuration. There is a possibility that the alarm system (EDW) could be triggered while the vehicle is parked and locked. MBUSA is conducting a service campaign. An authorized Mercedes-Benz Sprinter dealer will update the anti-theft system software on the affected vehicles.
LI49.20-N-079157_62025-07-01. Service bulletin. ELECTRICAL SYSTEM. Complaint The check engine light is activated, accompanied by one or more of the following fault codes related to the Adblue System: •P20F409: The Adblue consumption is too low. There is a component fault. •P202E84: The Adblue metering valve 1 (Motor side) has a malfunction. There is a signal below the permissible limit value. Cause The potential causes for these fault codes are: A. A leak in the Adblue System B. An internal fault with the Adblue Injection Valve #1 (Motor side) C. An air pocket forming in the Adblue Injection Valve #1 (Motor side) Adblue Injector Line Remedy Vehicles Produced Before August 1, 2024 (Code XY4 = MY24) A. Leak in the AdBlue System 1. Complete the Guided Tests for DTC P20F409 or P202E84: •Inspect the AdBlue tank, pump, line, and both injectors for leaks. •Ensure the AdBlue line is properly routed, securely fastened, and not in contact with the exhaust system. •Remove both AdBlue injection valves, perform 2–3 pressure build-ups, and check for AdBlue leaks. •If a leak is detected, repair it and retest. B. Internal Fault with AdBlue Injection Valve #1 (Motor Side) 1. Process All Other Related DTCs First: •Address any other fault codes relating to AdBlue injection valves before proceeding. •If AdBlue Injection Valve #1 (engine side) fails the guided tests, replace it and retest. C. Air Pocket Forming in the AdBlue Line (Motor Side) 1. If Guided Tests Pass and No Leaks are Found: --Do not replace any components.-- •The MY23-24 (Code XY4 = MY24, OM654) AdBlue line (A907 470 01 01) has a known design issue that can cause air pockets and DTC P20F409. This may also result in DTC P202E84, depending on the air pocket size. •The guided tests for P20F409 now include resetting the learned values for the AdBlue delivery pump (A103m1). After this, the vehicle can be released to the customer. NOTE: Replacing the AdBlue tank or line will NOT resolve this air pocket issue. TIPS cases are no longer required for MY23–24 vehicles. Steps to Perform (MY23–24, Code XY4): 1. Complete the guided tests for DTC P20F409 and/or P202E84. 2. Perform an initial start-up of: •The SCR control unit •AdBlue tank components •Both AdBlue injectors 3. Conduct a 20-mile test drive. If no faults occur, the vehicle can be released. 4. Inform the customer that frequent starting/stopping increases the likelihood of this fault due to repeated cycling of AdBlue in/out of the line each ignition cycle. Vehicles Produced After August 1, 2024 (Code XY5 = MY25) A. Leak in the AdBlue System 1. Complete the Guided Tests for DTC P20F409 or P202E84: •Inspect the AdBlue tank, pump, line, and both injectors for leaks. •Ensure the AdBlue line is properly routed, securely fastened, and not in contact with the exhaust system. •Remove both AdBlue injection valves, perform 2–3 pressure build-ups, and check for AdBlue leaks. •If a leak is detected, repair it and retest. B. Internal Fault with AdBlue Injection Valve #1 (Motor Side) 1. Process All Other Related DTCs First: •Address any other fault codes relating to AdBlue injection valves before proceeding. •If AdBlue Injection Valve #1 (engine side) fails the guided tests, replace it and retest. C. Incorrect AdBlue Injection Line Installed 1. Verify the Updated Line is Installed: •Confirm that part number A907 470 33 02 is present. •If the AdBlue line is incorrect (e.g., A907 470 01 01), replace it with the updated line. TIPS Case Instructions for All MY25 and Newer Vehicles If you encounter any of the issues above on any MY25 or newer vehicle, including finding an incorrect AdBlue line in- stalled: •Open a TIPS case addressed to the Powertrain inbox. •Reference this LI document. •Include the following information: •Description of the issue encountered (e.g., fault code, check engine light, or incorrect AdBlue injection line) •Current Quick Test, SCR N118/5 Control Unit Log, and Guided Test results. •Photo of AdBlue line part number label. •Photos documenting any issues, leaks, or melting observed
LI47.70-N-079422_12025-07-01. Service bulletin. ELECTRICAL SYSTEM. HV battery is not charging to its full capacity with restricted maximum SoC Complaint The vehicle's HV battery is not charging to its full capacity, with the maximum State of Charge (SoC) being restricted to a specific percentage. Cause The State of Charge (SoC) percentage limitation might be influenced by the Onboard Logic Unit (OLU), MBUX Headunit, or the Powertrain Control Unit (PTCU). Remedy If the Onboard Logic Unit (OLU) and MBUX Headunit do not impose a SoC percentage limitation, then proceed with the SCN coding of the Powertrain Control Unit (PTCU).

LI00.19-N-0757492023-02-03. Service bulletin. ELECTRICAL SYSTEM. Complaint Various issues including control unit programming procedure will not complete successfully/no newer software found, communication faults, or sporadic malfunction of systems. Cause Aftermarket CAN device could be installed into the vehicle's CAN network. Such devices can be but are not limited to, remote start modules, CAN blockers, or high idle modules. Remedy A successful control unit programming session cannot be ensured while aftermarket devices are connected to the vehicle's CAN network. Some of the device companies supply a bypass to allow control unit programming.
LI54.71-N-0756732023-01-05. Service bulletin. ELECTRICAL SYSTEM. Complaint Distronic and/or Active Brake Assist inoperative after driving for an extended period Cause Blindness detection of the radar sensor. When driving for extended periods in areas with few or no objects for the radar sensor to detect, the radar sensor switches off due to the self-test and sets fault code C174AFB - The adjustment of the 'Active Brake Assist' control unit has malfunctioned. Remedy • Check the area of the front radar for damage. • Check whether fault code "C174AFB - The adjustment of the 'Active Brake Assist' control unit has malfunctioned" is set in the B92 or B92/1 Active Brake Assist/Active Distance Assist DISTRONIC (ABA/DTR) (FCW177) control unit. • If the fault code is present, check the vertical actual values. • If these are not OK, please correct the value with inspection of installation position or calibration of installation height (see attachment 2021 NDTD_Vans_Radar Sensor for best practices and functionality info) • If the actual values are OK, please update the software.

LI54.21-N-0752962022-10-05. Service bulletin. ELECTRICAL SYSTEM. Complaint Customer purchased pre-owned MY18-21 ex-Amazon Sprinter (SA code Z3A) and does not want Amazon specific Parameterizable Special Module (PSM) functions (driver alert, idle shutdown, radio mute, etc). IMPORTANT NOTES: • Digital rear view display will no longer operate after Amazon specific PSM software is removed! • MY18 will show the reverse camera image on the Audio 15 screen. • MY19-21 will lose reverse camera functionality completely! Cause Strategic fleet customer removed the OEM rear view mirror with integrated reverse camera display to install an aftermarket digital rear view display that gets its power supply and reverse signal from PSM. When the Amazon-specific PSM software is removed, the aftermarket digital rear view display no longer has a power supply or reverse signal supplied by the PSM. It is not possible for the OEM PSM software to provide a power supply or reverse signal to the aftermarket digital rear view display. Remedy 1. Notify customer the aftermarket digital rear view display will not operate after PSM software is updated, AND: Reverse camera image will be displayed on the Audio 15 screen (MY18 ONLY) OR Aftermarket digital rear view display must be replaced with the OEM rear view mirror with integrated reverse camera display (MY19-21). 2. Perform software update of Parameterizable Special Module (PSM) using XENTRY > Adaptations > Control Unit Update > Updating of control unit software. This will remove fleet-specific PSM software and load the OEM PSM software from VeDoc. 3. MY19-21: Remove aftermarket rear view display and install OEM rear view mirror with integrated reverse camera display.
