  Summary

  Mercedes-Benz AG, the manufacturer of Mercedes-Benz vehicles, has determined that on certain MY 2020-2024 G-Class (463 platform) vehicles, the B-pillar certification label might not contain the vehicle’s rim size, tire size, and cold tire inflation pressure information as required by FMVSS 110 or FMVSS 120. In this case, relevant regulatory requirements might not be met. Mercedes-Benz believes this issue has no impact on vehicle safety. Mercedes-Benz intends to submit a petition to NHTSA for exemption from the notification and remedy requirements of 49 U.S.C. chapter 301, pursuant to 49 CFR Part 556, on the basis that this non-compliance is inconsequential as it relates to motor vehicle safety.

  Summary

  Complaint Customer complaints relating to automatic transmission 725.0 (NAG3 Classic / 9G-TRONIC automatic transmission) and 725.1 (NAG3 facelift/9G-TRONIC automatic transmission facelift) For faster, more effective and more targeted diagnosis, Intelligent Predictive Repair (IPR) has been developed and integrated into XENTRY Diagnosis. This ensures an automated diagnosis process. Cause As part of the on-going quality monitoring process and associated quality and damaged part appraisals, a high number of ineffective repairs have been discovered. Such ineffective repairs have a negative impact on all those involved. For the customer, it means high costs and long repair times and for the dealer, it may result in the warranty claim being rejected. Remedy General note: IPR is available for: ·NAG3 Classic (automatic transmission 725.0) ·NAG3 - AMG sports models (AMG 43 and AMG 53 with converter) ·NAG3 - AMG 63 ·NAG3 - Hybrid

  Summary

  In the instrument cluster, the symbol for "12 V battery" and the message "Switch on vehicle" may sporadically be displayed. As a consequence of this, the fault codes B1FCB97 (=> N73/3) and U116000 (=> N73/3*1) are stored in the fault memory. In the subsequent analysis of the 12 V on-board electrical system data, the following parameters are noteworthy (see picture 1 in the attachment): • Charge balance negative when stationary. • Interior CAN bus is awake for an unusually long time while the vehicle was locked. • 12 V battery SOC (state of charge) during subsequent engine start is 45% or less. NOTE: This LI does not apply if the CEL was reported as being on without a 12V message. Once the 12 V battery SOC has exceeded 50% for the first time, the symbol and the message in the instrument cluster disappear again. The door control unit (N69/x) may sporadically keep the interior CAN bus awake. NOTE:· Exclusively door control units with the HW item numbers A2239019917, A2239010018, A2239010118 and A2239010218 can be affected. Remedy Update the software on all 4 door control units (N69/1, N69/2, N69/3 and N69/4). For this, a commissioning of the door control units must be carried out on all 4 doors (N69/1, N69/2, N69/3 and N69/4). (Path: XENTRY Scope; Control units view; DCU-XX (N69/x); Adaptations; Commissioning) The repair software is available with add-on 28462 for XD DVD 09/23, with add-on 28463 for XD DVD 12/23 and/or as of XD DVD 03/24. SW item numbers of the repair software: · A2069020310 for the door control units at the front doors (N69/1 and N69/2) · A2069020410 for the door control units at the rear doors (N69/3 and N69/4)

  Summary

  Noises in the steering column area when steering. Under analysis. Check which area of the steering column the noises occur in. Do the noises tend to occur at the bottom in the driver footwell or do they tend to occur in the area of the steering column switch module (MRSM/SCCM)? If the noises occur in the area of the MRSM/SCCM, work through the following points: - Loosen screws of the MRSM/SCCM and steering wheel, re-align the MRSM/SCCM, and re-fasten the screws (see WIS). Sometimes there is stress at the MRSM/SCCM and noises occur. - If noises continue to occur, swap the MRSM/SCCM into a vehicle without any (noise) complaints. - If the noises occur with the MRSM/SCCM complained about when it is in the vehicle without a complaint (donor vehicle), the MRSM/SCCM can be replaced. - If noises also occur in the customer vehicle with the MRSM/SCCM from the reference vehicle, the MRSM/SCCM is not the cause and must not be replaced. Notes: - When installing the MRSM/SCCM, make sure that no damage occurs! - Only disassemble and mount all component parts in the "straight-ahead position" (see also WIS). - Please refer to this LI in the "Notes" section of the warranty claim!

  Summary

  The steering wheel generates grinding noises between the steering wheel and steering column switch module during steering maneuvers See example file in the attachments area: Lenkrad-Schleifgeräusch_SteeringWheel-GrindingNoises.mp4 The plastic cover on the back of the steering wheel is not positioned correctly and may therefore rub against the steering column switch module Please use the following noise files for the damaged part analysis: 1. Grinding noise | pot. cause: steering wheel | see attachment: Lenkrad-Schleifgeräusch_SteeringWheel-GrindingNoises. mp4 2. Creaking/cracking noise | pot. cause: steering column switch module | see attachment: MRSM-Schleifgeräusch_ SCCM-GrindingNoises.MOV If the noise is due to the steering column switch module, please use LI46.10-P-077314. Check for grinding areas on the steering wheel: Please check the covers on the rear for protrusion and, if necessary, remount. 1. Mask off openings on back of steering wheel with adhesive tape 1. Mark the back of the steering wheel with colored chalk (see Picture 1) 2. Mount steering wheel on steering column switch module and turn the steering wheel from left lock to right lock ten times. 3. The chalk will now have disappeared in the areas where there is rubbing (see Picture 2) Warning: Ensure that no cables and visible areas of the steering wheel are damaged. The abrasive excess material on the back of the steering wheel must be carefully removed with a Dremel tool. Tip: You will need to remove approx. 0.1 mm to 0.3 mm of material (example: Picture 3) Make sure that none of the ground-off material gets into the steering wheel. After removing the material, clean the entire back of the steering wheel with a 1% soap solution.
