  Complaint • The flush-mounted door handle could jam when it is pulled out and may move in a jerky manner when doing so. • In the area of the paneling section of the door, paint damage could be present (picture 1) and/or an abrasion point could be present at the door handle (picture 2). Cause The door handle could be installed too low in the y direction and/or the z direction (picture 3); as a result, the door handle could brush the door at the paneling section of the door. Remedy 1.) Loosen screws from bearing bracket (picture 4, step 1). 2.) Remove bearing bracket (see picture 4, step 2) from door. • The door handle must be in pulled-in position. • Open the affected door and push the door lock's rotary tumbler into the main catch. • Lock the vehicle using the transmitter key so that the door handle is pulled in. • Detach plug connector from bearing bracket (center slot). 3.) Paint over paint damage at door paneling (see picture 1) according to manufacturer specifications, using spot repair procedure if necessary. 4.) Loosen old assembly frame (picture 5, step 3). • The assembly frame is bonded. • Remove adhesive residue at front door. • Bonding surfaces must be free of dust, oil, grease, wax, dirt residues and other adhesive components. Otherwise, this can lead to bonding problems. • See "Parts" for part number of cleaning agent. 5.) Position new assembly frame (picture 5, step 3) at door. • Remove protective film of tape at assembly frame beforehand. • The assembly frame (picture 5, step 3) must have the same clearance all around the flange. 6.) Replace door handle, if an abrasion point (picture 2) is present. 7.) Screw in WITOL fasteners (picture 6) completely at mounting points of bearing bracket (picture 7, step 1) and align screws so that they are flush (picture 7, step 2). 8.) Position bearing bracket (picture 4, step 2). • The door handle must have the same clearance all around in relation to the paneling section of the door (picture 8). 9.) Press the bearing bracket firmly against the paneling of the door and tighten the screws (picture 4, step 1) (=> torque: 6 Nm). 10.) Check the positioning of the bearing bracket. If necessary, loosen the screws slightly, readjust the bearing bracket slightly, then retighten the screws (=> torque: 6 Nm).

  Summary

  Mercedes-Benz AG ("MBAG"), the manufacturer of Mercedes-Benz vehicles, has determined that on certain Model Year (“MY”) 2018 - 2024 E-Class, S-Class & AMG GT (213, 217, 222, 223 and 290 platforms) vehicles, the low pressure fuel line does not meet current production specifications. Therefore, it is possible that accelerated aging in the area of connection could occur, resulting in a leak. A risk of fire can be ruled out. MBUSA will conduct an Emission Service Campaign. An authorized Mercedes-Benz dealer will replace the braided hose of low-pressure fuel line and install a heat shield over the new braided hose.

  Summary

  Complaint Tension-releasing impact of the propeller shaft with the force-free in D "KID" function, after vehicle has stopped. Cause The tension-releasing jolt in the drivetrain originates as a result of the "release" of energy stored when braking through the force-free switch after stopping. It is suspected that the longitudinal bearing is being placed under tension here as a result of the vehicle "dropping off". Remedy 1. Mark the installation position of the joint prior to the removal (picture a+b). This is important for vehicles with a weighted drivetrain ex factory to ensure correct installation after operations have been completed. 2. Clean and degrease propeller shaft toothing. The toothing must be free of grease, e.g. through the use of a brake cleaner. Do not use wire brushes, else the surface could be damaged (picture c). 3. Coat propeller shaft toothing with A 000 989 16 08 Antifriction coating. Coat the entirety, ensuring that the subsurface is no longer visible. When doing so, only coat the outer toothing. Ensure that the coat is not too thick, otherwise the coating could chip (picture d). 4. Observe the drying time of at least 1 hour. 5. Lightly grease the propeller shaft toothing at the outer and inner toothing with A 001 989 44 51 12 Grease (picture e).

  Summary

  Complaint Headlamps leaking or fogged Cause The fogging of the headlamp is a natural phenomenon which can occur under certain climatic conditions. In contrast to a leaky headlamp, physical fogging does not result in a technical impairment of the headlamp. A leak test must be performed to determine if physical fogging exists or if the headlamp is leaky. Remedy In advance, observe LI82.10-P-078301 "Headlamps or Front Fog Lamps Leaking or Fogged". 1. Prepare headlamp/check for external damage: For headlamps with a closed system 1. Check the headlamps for any external damage and check also for correct seating of the Gore-diaphragm/correct latching of the cover caps. 2. If the headlamp exhibits any external damage, replace the headlamp. For headlamps with an open system 1. Check the headlamps for any external damage and seal off the vent then make sure the cover caps are latched correctly into place. 2. If the headlamp exhibits any external damage, replace the headlamp. Note: A headlamp with external damage is not a warranty or goodwill case. 2. Leak test of headlamp with overpressure: • Connect test adapter to pressure tester. (Figure 1) • Check test adapter for leak tightness. To do so, connect plug and coupling (picture 2) and apply a maximum overpressure of 30 mbar. The pressure must remain constant. If the pressure does not remain constant, use a new adapter. • Seal all the outlet openings using sealing compound and the given diaphragm with the plunger (picture 3). (Picture 4) Make allowance for the different headlamp variants here (there are different outlet openings). • Check if the headlamp needs to be removed to gain access to the diagnostic socket on the headlamp housing. • Plug the adapter onto the diagnostic socket on the headlamp housing. (Picture 5). • Apply a maximum of 30 mbar overpressure to the headlamp housing. Note: If the maximum overpressure of 50 mbar is exceeded the headlamp seal will be damaged. • If a pressure drop of less than 10 mbar is measured within 30 seconds, the headlamp is not leaky and the problem is down to natural physical fogging. • If a pressure drop of more than 10 mbar is measured within 30 seconds, the headlamp is leaky. Note: The leaky position can be localized with the aid of soap suds. Replace any leaky headlamps. Note: Desiccant packs can be installed for headlamps that are not leaky. See: • LI82.10-P-064766 Fogged headlamp, desiccant pack installed - open ventilation system • LI82.10-P-078304 Fogged headlamp, desiccant pack installed - closed ventilation system

  Summary

  Complaint Combustion engine could no longer be started, only electric driving possible Cause High-voltage belt-driven starter-alternator faulty Remedy Requirement: Prior to the implementation of the test work, it must be ensured that the person carrying out this work has successfully completed the qualification "T1716F Diagnosis at high voltage level 4" and the vehicle-specific training. Note: In order to check whether the high-voltage belt-driven starter-alternator is faulty, please carry out the test below. If the fault "P0E2F00 The electrical fuse B for the high voltage has a malfunction" is stored in the N82/10 BMS control unit, the HV protocol must be checked to see whether the fuse for the auxiliary consumers is defective. In this case, the high-voltage battery must be replaced after the short circuit has been eliminated. (See attachment) The faulty high-voltage belt-driven starter-alternator must always be sent back via the existing return delivery process for analysis. Check: Please disconnect the high-voltage plug at the high-voltage belt-driven starter-alternator and connect test adapter 000 589 94 63 00. Measure resistance HV+ to HV-. If the final measurement result is between 0–1 ohm, the high-voltage belt-driven starter-alternator with the short circuit must be replaced. If either one of or both the fault codes P0C0B16 and P0C0B17 are saved in the high-voltage belt-driven starter-alternator control unit G2/3, please replace the high-voltage belt-driven starter-alternator, since no short circuit can be measured here and this therefore concerns a hardware defect. Please check the serial number on the silver adhesive label below the SW number on the front of the high-voltage belt-driven starter- alternator. Example: 2314300044 (the first 10 digits, see attachment) Important note: If the number is greater than 2329100027, a TIPS case must be created. In this instance, please attach the following documents to the TIPS case: • Quick test • High-voltage event log • Picture of the silver adhesive label on the front of the high-voltage belt-driven starter-alternator (serial number) • Attach the measurement results with pictures
