Service bulletin 2023100006
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.

NHTSA's summary
Mercedes-Benz AG, the manufacturer of Metris vans, has determined that on certain Metris (447 platform) vehicles the fuel pump impeller might not meet specifications in regards to material characteristics. As a consequence, the impeller might deform and come into contact with the fuel pump housing, leading to a mechanical resistance. In some instances, this could lead to a shutdown of the fuel pump. As a result, the vehicle could lose propulsion, which could increase the risk of a crash or injury.

| LI49.10-N-080528 | 2026-07-02. 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. |

| LI47.50-N-072080_4 | 2026-06-02. Service bulletin. Check engine light on and FC P146264 stored in engine and fuel pump control units Complaint Check engine light active and FC P146264 Temp. and pressure sensor B4/15 is stored in Engine control unit and Fuel pump control unit. Cause Software parameter in Fuel pump control unit. Remedy Update fuel pump control unit (FSCU) to software version A0009024488 A0009030664. Clear fault codes and check for any additional symptoms. |
| LI07.70-N-078824 | 2025-03-04. Service bulletin. Complaint Fault code P06DA00 is found current or stored in engine control unit. Check engine light may be activated. Cause Various causes Remedy Up to Model year 2018: Fault code P06DA00 can be disregarded if not activating the check engine light, unless otherwise specified in the gui- ded test. The vehicle continues to operate as designed. Further causes should be investigated if complaint of check engine light is received. Model year 2019 and later: Fault code P06DA00 will activate check engine light as of model year 2019. No driveability concerns will be observed, only illumination of the CEL. This fault code indicates high resistance or open in the circuit to Y130 oil pump control valve. Perform guided test for component Y130 under list of tests in ME. Diagnose location of high resistance or open in Y130 circuit and repair as necessary. Warranty claims submitted without supporting guided test results may be subject to debit. |
