Check engine light with fault code P300E5F and/or P300E5E in MRD1 (CDI) Complaint The check engine light is on, with a possible reduction in power. No soot is present in the exhaust system. Fault codes: P300E5F ‑ The fill level of the Diesel Particulate Filter is too high. Early warning. P300E5E ‑ The fill level of the Diesel Particulate Filter is too high. Regeneration of the Diesel Particulate Filter is disabled. Additional information: No additional fault codes related to the Diesel Particulate Filter or Exhaust Gas Recirculation system may be present for this LI to apply. Cause These fault codes may be triggered due to unfavorable driving conditions, such as: •Frequent short‑distance trips •Extended idle periods •Infrequent highway driving •Incomplete regeneration cycles These conditions can lead to excessive soot accumulation in the Diesel Particulate Filter, resulting in elevated fill levels and regeneration lockout. Remedy Fault code P300E5F indicates that the Diesel Particulate Filter soot load has exceeded 130% but remains below 160%. Regeneration remains permitted. Fault code P300E5E indicates that the Diesel Particulate Filter soot load has exceeded 160%. Regeneration is disabled to protect components. 1. Perform a tailpipe wipe test Inspect the tailpipe for soot using a clean white cloth. • If soot is found, stop this procedure and follow LI49.20‑N‑078466. • If no soot is found, continue with Step 2. 2. Check the Diesel Particulate Filter data Using XENTRY, review and save the following information: • Diesel Particulate Filter fill level • Calculated soot load • Ash load • Regeneration history • Distance and operating time since the last successful regeneration • Relevant exhaust‑temperature and differential‑pressure actual values Process any additional fault codes according to the applicable Guided Tests before attempting regeneration. 3. Perform a manual standstill regeneration Perform a manual standstill regeneration of the Diesel Particulate Filter according to the current XENTRY instructions. • Save or print the regeneration results. 4. If the manual standstill regeneration completes successfully Clear the fault memory and verify that the Diesel Particulate Filter actual values are plausible. • Confirm that the applicable fault codes do not return. • Complete a road test and confirm that no fault codes return. • Use damage code 14370F7 if the vehicle is under warranty. Release the vehicle only after proper Diesel Particulate Filter operation has been confirmed. 5. If the manual standstill regeneration does not complete successfully Replace the Diesel Particulate Filter according to the current Workshop Information System instructions. • Confirm that the MRD1/CDI control unit has the latest available software. Update the software if it is not current. • Thoroughly inspect the exhaust system downstream of the Diesel Particulate Filter for soot. • If soot is found, follow LI49.20‑N‑078466 for the required inspection and replacement of affected components. • Complete all required teach‑in, initial startup, and reset procedures after the repair. • Clear the fault memory and perform a road test. • Recheck the fault memory and verify that the Diesel Particulate Filter actual values are plausible.

Check engine light with fault code P3005CA in MRD1 (CDI) Complaint The check engine light is on, with a possible reduction in 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 detects soot or debris downstream of the underbody SCR catalytic converter. Remedy Note: The XENTRY guided tests for fault code P3005CA have been revised. Complete all applicable guided tests before replacing components. TIPS cases are no longer required unless: • No soot is found at the Diesel Particulate Filter (DPF) outlet. • The fault occurs on a vehicle produced after the applicable production clean point. • The fault returns after the applicable repairs have been completed. • The fault occurs on a vehicle confirmed to have the latest available MRD1/CDI control unit software.

Sprinter 907 ‑ Oil leak in area of wheel hub / rear axle shaft Complaint Oil leak in the area of the wheel hub Cause Insufficient sealing with previous axle shaft with single sealing lip Remedy New axle shafts have been created with a dual lip style seal. New part numbers: A 906 350 37 10 ‑‑> A 907 350 19 03 ( left / ring gear 215 ) A 906 350 38 10 ‑‑> A 907 350 20 03 ( right / ring gear 215 ) A 906 350 39 10 ‑‑> A 907 350 21 03 ( left / ring gear 245 ) A 906 350 40 10 ‑‑> A 907 350 22 03 ( right / ring gear 245 )

Check engine light with reduced power with fault codes P300A6D, P300974, P300DFB, or P300DE8 Complaint The check engine light is activated, accompanied by one or more of the following fault codes related to the boost pressure positioner: • P300A6D: The boost pressure is too low. Charge air cooler. • P300A6F: The boost pressure is too low. (High‑pressure turbocharger) • P300A71: The boost pressure is too low. (Low‑pressure turbocharger) • P300974: Component 'Boost pressure positioner' has a malfunction. The boost pressure is too low. • P300DFB: Component 'Boost pressure positioner' has a malfunction. • P300DE8: Boost pressure control A has a malfunction after a cold start. Cause The potential causes for these fault codes are: A. Leak or Blockage in the Intake or Charge Air System: This can prevent proper airflow, affecting boost pressure. B. Insufficient Source Vacuum, Vacuum Leak, or Sticking/Weak Vacuum Component: These issues can prevent the boost pressure positioner from functioning correctly. • For Model Year 2023‑Current vehicles operating at approximately 4,000 ft elevation or above, reduced ambient pressure and/or high brake demand may contribute to reduced available vacuum differential and underboost complaints, even when no discrete vacuum component failure is identified. C. Internal Malfunction of the Boost Pressure Positioner: The component itself may be faulty. D. Internal Defect with the Variable Turbine Geometry (VTG) System Inside the Turbocharger: Issues within the turbocharger can affect boost pressure control.

EGR Valve Diagnosis & Cleaning (and EGR Cooler Cleaning) – OM642, Sprinter 906/907 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 desired target of the EGR Valve position controller. Cause of Complaint C: Internal EGR Valve or other electrical faults related to the EGR Valve function.
