SummaryASSYST PLUS service reminder appears earlier than expected due to vehicle operating conditions Complaint The ASSYST PLUS service reminder appears earlier than expected. The customer or dealer may report that the vehicle did not reach the starting maintenance interval shown in vehicle documentation, option coding, sales literature, or the Owner's Manual. The service reminder may appear significantly earlier than anticipated even though no faults are stored and no malfunction is present in the vehicle. The remaining distance and remaining time continue to decrease normally until the service reminder is displayed. Cause This condition is not caused by a malfunction of ASSYST PLUS. ASSYST PLUS is a dynamic maintenance management system that continuously evaluates vehicle usage and opera-ting conditions to determine maintenance requirements. The starting maintenance interval specified by variant coding represents a maximum interval that may only be achieved under favorable operating conditions. Actual maintenance intervals may be significantly shorter depending on vehicle use. Vehicle operating conditions such as driving conditions, engine load, engine operating conditions, idling, short-trip operation, environmental influences, oil aging, and Diesel Particulate Filter (DPF) regeneration activity may reduce the maintenance interval from its starting value. These conditions may accelerate engine oil aging through increased soot loading, fuel dilution, moisture accumulation, and additional engine operating stress. As a result, the remaining distance and remaining time until the next service may be reduced from the starting maintenance interval. Remedy Do not replace any parts. A due service must be assumed if the maintenance data calculated by ASSYST PLUS indicates that service is required.

SummaryOM642 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.

SummaryWarning Lamp "Washer Fluid Empty" Yet Reservoir Is Not Empty Complaint: Warning lamp "washer fluid empty", even thought the washer fluid reservoir is full Cause: Insufficient electrical conductivity of the washer fluid, as the washer fluid was mixed with distilled water. Tip: The washer fluid sensor detects the electrical conductivity. If air is present without electrical conductivity between the measuring points, as is the case with an empty tank, an empty tank is detected by the sensor. Distilled water also does not have electrical conductivity, meaning that the sensor detects an empty tank, even if this is not the case. Remedy: Fill reservoir with standard washer fluid and water (no distilled water) in an adequate ratio in order to ensure electrical conductivity. Exchange of the reservoir with a welded-in sensor is only required if filling with conductive washer fluid has not provi- ded a remedy. This can be made certain by utilizing water with a light amount of salt dissolved in to it for stronger con- ductivity.

SummaryComplaint: Noises when reversing slowly <5 km/h (squeaking) Cause: There is a seal in the electric drivetrain that seals off the coolant system from the electric motor. This seal is moistened with coolant during forward travel. As a result of the change in rotational direction when reversing slowly, it may be the case that this sealing ring is no longer moistened. Squeaking noises may occur as a result of the so-called "stick-slip effect". This behavior does not impact the function or durability of the sealing ring and electric drivetrain. Remedy: Do not replace any parts. Explain the cause of the noises to the customer.

SummaryMercedes-Benz AG 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. It might therefore 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, and increase the risk of a crash or injury.
