LI27_20_N_080998_12026-10-06. Service bulletin. Sprinter 907 with 725.0 (NAG3 Classic) Transmission ‑ Shudder during acceleration Complaint Shudder may be felt in the following situations: • accelerating from stop or up hill • during upshifts Cause Under Investigation, possible torque converter clutch operation
LI28_00-N-079097_1_en2026-09-04. Service bulletin. Complaint While driving through muddy / sandy/ off road terrain "4Matic Currently Unavailable" message on the dash Cause This vehicle is not equipped with a fixed force distribution AWD, rather force is only applied to the front axle according to ESP calculations. As per GF28.00‑D‑ 9900A: "vehicles with 4MATIC all‑wheel system and variable force distribution, an electronically regulated multiplate clutch integrated into the transfer case provides for the torque distribution. If the multiplate clutch is open during normal driving operation, only the rear axle drives the vehicle. If the clutch is closed, the front axle comes into play." The message "All‑wheel drive temporarily unavailable" is not indicative of a malfunction but rather informs the driver that all‑wheel drive is currently not available due to the transfer case clutch overheating. This occurs when the vehicle is driven in such a way that maximum front axle torque is needed for an extended period, causing the clutch to get excessively hot. If the vehicle is being driven under heavy load conditions, like in deep sand or snow, the rear axle may slip while the front axle does not deliver power. The transfer case then attempts to distribute torque to correct the slip, but it is limited to a maximum of 1150 Nm to protect the front axle transmission. In extended heavy‑load scenarios, the multidisk clutch in the transfer case slips, increasing the temperature. If the temperature model detects a critical temperature of 240°C, the system protects itself by disconnecting until it cools down to around 160°C, after which the all‑wheel drive becomes available again and the warning message disappears.Vehicles can handle flat terrain easily, but steep slopes or situations where wheels slip might cause additional resistance, leading to the described protection events and message in the dash. Remedy Recommendation is to release the vehicle back to the client with an explanation that the vehicle is operating as designed. Please advise the client to limit vehicle acceleration in limited traction situations to avoid disabling of the 4Matic system ‑ please see "Notes on all‑wheel drive" provided in the operators manual.
LI33_30-N-0807952026-08-03. Service bulletin. Model 907 with all-wheel drive (A4M) – All-wheel drive inoperative Complaint The customer may report one or more of the following: • All-wheel drive is unavailable or inoperative. • Rear wheel slip during acceleration on low-traction surfaces. • Noise from the front axle area while driving. • Message in the instrument cluster indicating all-wheel drive is unavailable due to overheating. • Fault code P27874B - The temperature of the clutch is too high. There is a fault due to overtemperature may be stored in control unit N15 (Transfer Case). Cause An internal failure of the front axle differential may result in loss of torque transfer to the front wheels. In some cases, a fracture of the weld between the crown gear and differential housing may be present. Remedy Replace the front axle differential in accordance with: AR33.30-D-0525TSY – Replace Front Axle Differential.
LI49.10-N-0805282026-07-02. Service bulletin. OM642 DPF Filter Cracked or Broken Complaint Vehicle will not start or exhibits noisy exhaust. Check Engine Lamp (CEL) is on. Multiple control unit communication and system faults may be present, including but not limited to: 134800, 134900, 11B300, 11EC00, 15E100, 155700, 162500. Additional events codes may include: 134300, 102200, 163400, 16CE00. In many cases, multiple unrelated faults are stored due to electrical disruption from wiring damage rather than indivi-dual component failure. Cause The DPF filter is cracked, broken, or leaking, allowing hot exhaust gas to escape from the exhaust system. Depending on the location of the break or leak, hot exhaust gas may be directed toward the main wiring harness and/ or the SCR (Selective Catalytic Reduction) dosing valve assembly. This heat exposure can result in: • Internal melting of wiring insulation within the harness • Short to ground conditions and loss of communication between control units • Damage to the dosing valve and/or heated AdBlue line Damage to the wiring harness may not be visible externally, as the outer tape can remain intact while the internal wires are melted and fused together. Remedy Inspect the DPF assembly for cracks, separation, or leakage. Do not proceed with further diagnosis or component replacement until the exhaust leak source has been identified and confirmed. If any damage is found, replace the DPF filter assembly. Based on the location of the failure, inspect all components in the path of the exhaust leak, including the dosing valve assembly and main wiring harness. The wiring harness must be opened in any area exposed to the exhaust leak to visually inspect the individual wires. External inspection alone is not sufficient to determine harness condition. Repair or replace any damaged wiring in accordance with approved repair procedures. Replace any dosing system components that show signs of heat damage. Failure to identify and repair all heat-affected components will result in repeat faults or no-start conditions.
LI00.20-N-0806262026-07-02. Service bulletin. Complaint ASSYST values in XENTRY actual values and workshop menu of instrument cluster are implausibly excessive. Infor-mation: According to ASSYST values in XENTRY Diagnosis and the instrument cluster workshop menu, a larger jump (for example 20,000 km or 12,500 miles) has been detected within one ignition cycle that does not match the usual customer usage pattern/maintenance history. Cause Differences between the ASSYST memory in the control units for the drivetrain (N127) (CPC) and the instrument clus-ter (A1) (IC) Remedy 1. Connect 12 V charger (see AR54.10-D-1127TS for models 907). Note: An adequate voltage from the on-board electrical system battery must be guaranteed for the entire duration of the work procedure. Otherwise the control units could be damaged if an undervoltage occurs. Information: Observe the operating instructions of the 12 V charger. Information: Use the 12 V charger to ensure a sufficient voltage (minimum 12.5 V) from the on-board electrical system battery.
LI47_00-N-0695652026-07-02. Service bulletin. Fuel Level Unchanged After Refueling Complaint The customer reports that the fuel gauge shows inaccurate readings or remains unchanged after refueling. Cause A. The Fuel Supply Control Unit (FSCU) fails to detect a refueling event B. The Fuel Level Sensor provides incorrect readings due to mechanical interference or installation issues
LI14.20-N-0738672026-07-02. Service bulletin. Complaint Complaint A: The engine is jolting/bucking between 1700 and 1900 rpm. Complaint B: One or more mechanical related fault codes for EGR Valve stored in CDI control unit, with possible Check Engine Light. Review list of mechanical fault codes in table below. NOTE: If one or more electrical related fault codes for EGR Valve are also present in CDI, utilize Complaint C. Review list of electrical fault codes PDF document in attachments. Complaint C: One or more electrical related fault codes for EGR Valve stored in CDI control unit, with possible Check Engine Light. Review list of electrical fault codes PDF document attached. NOTE: This LI supersedes LI14.20-N-073813, which is no longer valid. Cause Cause of Complaint A: Increased friction between the EGR Valve blade and seat due to soot deposits causing a delay of the EGR Valve being able to reach the target value of the EGR Valve position controller. NOTE: This causes the EGR Valve blade and potentially the boost pressure controller to oscillate. Cause of Complaint B: Soot deposits between the EGR Valve blade and seat leading to the EGR Valve no longer being able to meet the de-sired target of the EGR Valve position controller. Cause of Complaint C: Internal EGR Valve or other electrical faults related to the EGR Valve function. Remedy Remedy for Complaint A: Perform the following steps: 1. Disable the EGR Valve (Y27/17) by disconnecting the electrical connector. 2. Perform a test drive to check if the jolting/bucking issue resolves. 3. If the jolting/bucking is resolved, proceed to Remedy for Complaint B. 4. If jolting/bucking is still present, proceed with diagnosis to determine the root cause. Consider checking the follo-wing, but not limited to: •EGR system including the EGR Cooler, EGR Bypass Flap, EGR Temperature Sensor, and pipes for proper operati-on, excessive sooting and/or clogging, as well as EGR Bypass Flap vacuum element, switchover valve, and vacuum system. •Visually check the leak oil line or T-piece; reference LI07.00-N-059118.
LI49.20-N-078466_42026-06-02. Service bulletin. Check engine light with fault code P3005CA in MRD1 (CDI) Complaint The check engine light is on, with a possiblility in a reduction of power and the presence of soot in the exhaust system. Fault code P3005CA: The diesel particulate filter efficiency is insufficient. Additional information: Additional fault codes may be present, related to the Diesel Particulate Filter (DPF) system or the Exhaust Gas Recirculation (EGR) system. Cause This fault code sets due to the following factors: 1. Damage to the Diesel Particulate Filter (DPF) unit. 2. The N74 (Soot Particulate Sensor Control Unit) identifies soot or debris located downstream of the SCR Catalyst (underbody). Remedy Note: The guided tests for fault code P3005CA have been revised in the XENTRY unit. It is important to complete these guided tests thoroughly. TIPS cases are NO longer required unless there is an absence of soot at the outlet of the Diesel Particulate Filter (DPF) unit. If there are any other fault codes present for component 'N74 (Soot Particulate Sensor Control Unit)', process these first. 1. Damage to the Diesel Particulate Filter (DPF) unit. • Complete the XENTRY guided tests: • Check the Exhaust system for leaks - Perform a visual inspection of the exhaust system from the Combustion Engine to Diesel Particulate Filter (DPF). Verify that there are no external damages and that all clamps and sensors are installed and leak-free. • Check component 'Exhaust pipe and Filter screen of Exhaust Gas Recirculation (low pressure)' for carbon fouling. If no soot is present at the Tailpipe outlet, recommended to separate the exhaust pipe downstream of the Diesel Particulate Filter (DPF) at the outlet to inspect.
LI35.00-N-080267_12026-06-02. Service bulletin. Sprinter 907 - Rear Axle Noise Diagnosis Best Practices Complaint Various noises from area of rear axle while driving Cause A: Howling Noises The high‑frequency howling noise is caused by the normal meshing behavior of the rear axle gear set, consisting of the pinion and crown gear. Two example noise recordings are provided in the attachment for reference. The volume and perception of this noise can vary depending on vehicle weight and load condition. Due to the current design of the Sprinter rear axle, it is not possible to completely isolate or decouple the the vibration generated by the normal meshing of the rear axle gears from the vehicle body. As a result, this noise may be transmitted into the vehicle interior. This noise is considered a normal characteristic of the rear axle design and vehicle operation. As it is not the result of a technical failure, component repairs or replacements will not lead to an improvement. There is no negative impact on the function, durability, service life, or operational safety of the rear axle. B: Other Noises: Noises that differ from the described howling characteristic (for example grinding, droning, or chattering noises) are not considered normal and may indicate a technical concern. Possible causes may include, but are not limited to: • Damaged bearings • Increased or abnormal gear wear • Excessive play within the differential Remedy Remedy for Cause A: Do not replace any components. This noise is considered a normal characteristic of the rear axle design and vehicle operation. Remedy for Cause B: If the noise does not match the described howling characteristic, the concern must be diagnosed and documented using the guidance below, with the results included in the warranty claim as applicable. Documentation of Concern: In many cases, the concern can be remedied using available replacement parts, and a complete rear axle assembly replacement is not necessary. However, due to parts availability, tool availability and workshop constraints, a complete assembly replacement may be performed in select cases to mitigate vehicle downtime. IMPORTANT: This is not intended to be the default repair approach. Component replacement must not be performed without diagnostic findings that clearly support a technical defect. Replacing rear axle components without confirmed abnormal findings may result in a debit of the warranty claim. This document does not guarantee warranty coverage and is designed to aid in diagnosis and subsequent resolution of the complaint. Create a file with all of your documents, findings, photos and sound files. 1. To ensure there is a clear understanding of the customer complaint, collect and document the following information: - When did the noise start? - Verify whether any previous repairs or work were performed prior to the onset of the noise. - Did the noise occur suddenly, or did it develop progressively over time? - Is the vehicle upfitted, modified, or retrofitted? (List all modifications) - Attach photos of any modifications or added equipment. - Under which conditions does the noise occur? (Provide all that apply) • Vehicle speed • Selected gear • Load condition • Outside ambient temperature and/or weather conditions • Engine and drivetrain temperature Diagnosis and Inspection: 2. Collect a video or sound file of the noise concern, ensure the video is available if requested. 3. Perform an NVH recording and store the .pp data file. The file must be available if requested during warranty review or parts inspection.
