Service bulletins for the 2024 Freightliner Sprinter
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.

| LI07.16-N-080732 | 2026-07-02. Service bulletin. FUEL/PROPULSION SYSTEM. Complaint The customer reports that the engine cranks but does not start, or only starts after extended cranking. A check engine light may be present, and fault codes P300616 (The fuel pressure in the system is too low) and/or P300617 (The fuel pressure in the system is too low) may be stored, along with other fuel pressure-related fault codes. Cause Insufficient high-pressure fuel build-up during engine cranking. The fuel system does not achieve the required rail pressure of >120 bar, preventing engine start. This condition may be caused by internal leakage within the fuel injection system, inadequate fuel supply from the low-pressure circuit, or a malfunction of the high-pressure fuel pump. Remedy 1. Verify high-pressure fuel rail pressure during engine cranking using XENTRY actual values. • Evaluate the actual value “The starter turns and the combustion engine does not start” and monitor high-pressure fu-el rail pressure during cranking. (See attachment: XENTRY actual values – rail pressure not reaching >120 bar) • The system must achieve a minimum of >120 bar in order to enable engine start. → If the specified rail pressure is not achieved, perform the following checks: 2. Check low-pressure fuel supply • Verify fuel quality (color, clarity, separation, contamination) • Inspect fuel tank, fuel filter, and low-pressure fuel pump for debris, restriction, or damage • Measure low-pressure fuel supply before and after the fuel filter and confirm values are within specification • Perform a fuel volume test at the high-pressure pump inlet to ensure adequate delivery • Verify that the injector leak line is installed correctly, remains unmodified, and is not restricted or kinked → If low-pressure fuel supply is not within specification: Repair as necessary and recheck high-pressure fuel build-up 3. Check for internal leakage within the fuel injection system • Perform a fuel injector leak/return test using XENTRY • Evaluate injector leak-back during cranking NOTE: If the combustion engine does not start, perform the test by cranking the engine 3–4 times for approximately 15 seconds each, instead of allowing the engine to run for approximately 60 seconds → If injector leakage is present: Replace the affected injector(s) and perform injector teach-in 4. Check high-pressure fuel system • If no leakage is identified and low-pressure supply is sufficient, evaluate high-pressure fuel generation → If high-pressure fuel system does not generate sufficient pressure: Replace the high-pressure fuel pump 5. Final verification • Verify that rail pressure exceeds >120 bar during cranking • Confirm the engine starts normally without extended crank • Clear fault codes and perform final validation |

| LI49-20-N-075995 | 2026-04-02. Service bulletin. UNKNOWN OR OTHER. Vehicles with SCR Generation 4: SCR/AdBlue® warning message cannot be reset with fault code P13DF00 or P300685 Complaint SCR or AdBlue warning message cannot be reset. All fault codes in the AdBlue (SCR) control unit have been processed and corrected, however fault codes P13DF00 or P300685 remain active and stored. Cause The procedure for resetting the SCR or AdBlue warning message with XENTRY Diagnosis has not been carried out. Note: If AdBlue quality or concentration related fault codes are present, such as P300494, P203B31, or P206B31, complete the applicable diagnostic procedure first. This includes the thaw, mixing drive, and retest requirements in LI49.20-N-080376 and the detailed diagnosis and re-pair steps in LI49.20-N-078838 as applicable. Do not attempt to reset the SCR or AdBlue warning message until the underlying fault condition has been corrected. Remedy Note: Do not replace any parts for an incorrectly executed reset procedure. 1. Connect the battery charger •Maintain adequate voltage throughout the procedure per applicable guidance. 2. Connect the diagnostic device •Use the latest version of XENTRY Diagnosis and Add-Ons. 3. Reset the SCR or AdBlue warning message using XENTRY Diagnosis •Quick test view → N118/5 – Selective Catalytic Reduction (SCR GEN4) → Special processes → Reset SCR/AdBlue® warning message. Note: Ensure all 5 listed processes are completed successfully, indicated by Actual value: "successfully completed". 4. Complete the disconnect and sleep mode initiation procedure •Disconnect XENTRY. •Refer to manual AD00.00-D-2000-06TS for the correct procedure to disconnect the diagnostic device from Model 907. •Disconnect the Battery Charger •Refer to manual AR54.10-D-1127TS for instructions on safely disconnecting the battery charger from Model 907. •Turn off the ignition. •Remove the key. •Lock the vehicle and wait approximately 15 minutes to allow the CAN bus system to enter sleep mode. 5. Post sleep mode vehicle start •After the 15-minute waiting period, start the vehicle. Note: The "starts remaining" message will remain on the Instrument Cluster (IC), but the vehicle will not be in the 5mph de-rate mode. 6. Drive for system self-test •Drive the vehicle for 5 to 10 miles to enable the SCR system to perform a self-test. Note: During the warning reset process, ensure the outside temperature sensor is reading above 10 degrees Fahrenheit. If not, keep the vehicle inside and repeat the reset. The vehicle may need to be driven to allow NOx sensors and the SCR system to complete their self-test before fault codes can be stored and then cleared. 7. Confirm and erase fault codes •Verify warning messages. •Ensure relevant fault codes are stored. •Erase fault memory if necessary. 8. Disconnect the Diagnostic Device •Refer to manual AD00.00-D-2000-06TS for the correct procedure to disconnect the diagnostic device from Model 907. 9. Disconnect the Battery Charger •Refer to manual AR54.10-D-1127TS for instructions on safely disconnecting the battery charger from Model 907. |
