LI01.10-N-0792752025-10-07. Service bulletin. Internal Diesel Engine Damage or Oil Sludge Formation Complaint Customer reports that the vehicle will not start, is difficult to start, or is making unusual noises. Inspection Findings: Upon inspection, engine bearings—including crankshaft, connection rod, and camshafts—exhibit significant signs of wear. Engine oil shows evidence of sludging, characterized by the presence of thick, gel-like, or semi-solid deposits within the engine. This condition is indicative of oil degradation and/or contamination. Cause Internal engine wear and starting issues are a result of oil sludging. This sludging occurs due to oil degradation and/or contamination. Common contributing factors include: •Failure to perform maintenance on time as indicated by the ASSYST PLUS system •Use of non-OEM (aftermarket) parts or fluids •Addition of incorrect fluids (e.g., AdBlue, washer fluid, coolant) to the engine oil, which can severely compromise lub- rication and engine operation Important: Under no circumstances should any non-engine fluids—such as AdBlue, washer fluid, or coolant—be ad- ded to the engine oil or crankcase. The introduction of these fluids, even in small amounts, can cause severe engine damage. This damage is not covered under warranty. Always verify that only approved engine oil and additives are used during service.
20250800082025-10-07. Service campaign. Mercedes-Benz AG, the manufacturer of Sprinter vehicles, has determined that on certain Freightliner Sprinter (907 platform) vehicles, 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. DVUSA is conducting a service campaign. An authorized Freightliner Sprinter dealer will update the anti-theft system software on the affected vehicles.
LI49.20-N-079157_62025-07-01. Service bulletin. 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
