  Summary

  In our continuing efforts to assure the proper performance of Mercedes-Benz products and to enhance the satisfaction of our customers, Mercedes-Benz USA (“MBUSA”) is extending the coverage for the intake line assembly on your vehicle from the original New Vehicle Limited Warranty of 4 years / 50,000 miles to 15 years / 150,000 miles (whichever occurs first), and applies to the vehicle regardless of ownership. Why the warranty extension? On certain Model Year 2015 - 2020 C/E/GLC/SLC and SLK vehicles, under certain circumstances, the partial-load ventilation valve (a part of the intake line assembly) may not work as intended, resulting in the illumination of the check engine Malfunction Indicator Lamp (‘MIL’). A faulty partial-load ventilation valve might also increase exhaust gas emission. . Any repairs under this warranty extension must be performed by an authorized Mercedes-Benz dealership. • If your preferred authorized Mercedes-Benz dealership performs a diagnosis and confirms that your vehicle has the issue, the repair will be performed at no cost to you. • This extended warranty does not apply to any other components or conditions beyond the ones mentioned above, and standard warranty terms apply, including the exclusions with respect to extra expenses, as identified in the Service and Warranty Information booklet. We hope you are enjoying your Mercedes-Benz vehicle and we apologize for any inconvenience this may have caused.

  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 B 1 FCB97 (=> N73/3) and U 116000 (=> N73/3*1) are stored in the fault memory. In the subsequent analysis of the 12 Von-board electrical system data, the following parameters are conspicuous (see picture 1 in the attachment): • Charge balance negative when stationary. • Interior CAN bus is awake for an unusually long time. • 12 V battery SOC (state of charge) during subsequent engine start is 45% or less. NOTE: 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 and A2239010018 can be affected. Open a TIPS case and include the following: 1. Initial Quick Test 2. N73/3 EZS CUL 3. N73/3*1 EZS CUL 4. Date and time of occurrence

  Summary

  Noise at front seats between seat-back lining and function carrier. Noise is caused by friction of the two component parts. Remove the seat-back lining (back panel) of the front seat concerned using a special tool. Via adhesive bonding, affix 2 pieces of felt at the lower seat backrest structure (see pic. 1). Via adhesive bonding, affix 2 pieces of felt in the upper area of the seat backrest at the function carrier (see pic. 2). Pic. 3 shows the function carrier from behind: Begin applying the adhesive bonding of the felt at the edge (see red arrow). Ensure that the adhesive bonding is applied in the center. Then fold the felt forward. Pic. 4 shows the function carrier from the front: Continue to apply the adhesive bonding to the forward fold. Ensure that the adhesive bonding is applied in the center.
