  Summary

  Complaint Noises in the steering column area when steering. See example file in the attachments area: "MRSM‑Schleifgeräusch_SCCMGrindingNoises. MOV". Cause Under analysis. Remedy 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! ‑ If the noise is due to the steering wheel (see attachment "Lenkrad‑Schleifgeräusch_SteeringWheel‑GrindingNoises.mp4"), please use LI46.10‑P‑077313. ‑ 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

  Complaint Noises/ squealing from the service brake in various driving situations and ambient conditions. Cause Frictional vibrations Remedy The intent of this document is to reduce noise from high performance AMG brakes. AMG brakes are designed for performance under high load and in certain scenarios, can emit noise. Some scenarios are normal and some are induced by driving style like those listed below: • Driving style such as two footed driving where the pad might be in constant contact with the rotor. • Brake pressure and application style (stop‑and‑go traffic with consistent light brake pressure “riding brakes” where the brakes cannot cool sufficiently between applications). This can cause the brake pads to glaze and have a smooth/glassy surface which can induce noise. • When ambient temperatures rise during summer peak and during cooling and cold winter months. 1. Beginning Diagnostics: a) Check whether the complaint can be reproduced and at which axle or side the noises occur (ideally together with the customer while driving). b) Check the affected system for component wear, mechanical damage or localized overheating damage. Replace damaged components as necessary. c) Assess condition of brake rotors and pads per WIS and visually (i.e. long periods of stagnation, etc...). d) Clean brake components free of brake dust and debris. d) Secure vehicle on a lift. 1. Start the engine and depress the brake pedal 3‑4 times. 2. Check each wheel to see if they turn freely by hand. 3. If a wheel is not turning freely by hand, this needs to be addressed prior to re‑assessing the noise concern. e) Check whether, apart from this document, an additional document exists for the specific model in question, and if so, work through it and then continue. 2. Specific Axle Work: NOTE: If the brake pad has a metal backing plate, there is no need to affix the adhesive film. Continue with applying chamfer and Molykote as instructed below. IMPORTANT: Be absolutely certain to not allow paste between friction surfaces of the pad and disc! a) If the noises are coming from the front axle. 1. Remove brake linings of front axle. 2. Clean all contact points on brake lining backing plate, including the brake lining guide pins and brake caliper/carrier. 3. Clean bonding surface (where pistons contact back of brake pad). Apply adhesive film to the backplate of the piston‑side brake lining where the piston contacts the pad backing plate. See picture "Adhesive and Paste Application Area". 4. Be sure to remove both brown paper backing sides of the adhesive film, it is double sided adhesive film. 5. If adhesive is already installed on backing plate where pistons contact the back of the pad, you may gently scrape off and re‑apply a new adhesive or Molykote. Must not apply the Molykote on top of the adhesive. 6. Chamfer edges (gently round off sharp leading edges) on brake pads. Some pads have vertical grooves, these can be gently chamfered with a triangular file as well. See picture "Chamfering Technique". 7. Apply Molykote to the sides of the backing plate. See picture "Adhesive and Paste Application Area". 8. After installing the brake linings, actuate the brake for 30 seconds. b) If the noises are coming from the rear axle. 1. Remove brake pads of rear axle. 2. Clean all contact points on brake lining backing plate and brake caliper /carrier. 3. Clean bonding surface (where pistons contact back of brake pad). Apply adhesive film to the backplate of the piston‑side brake lining. 4. Chamfer edges (round off sharp leading edges) on brake pads. See picture "Chamfering Technique". 5. Grease contact points (red areas on attachment "Rear Pad Grease Area") between brake lining and guide of brake caliper with Molykote. 3. Brake Bedding Process: a) Before trip, the mileage incurred must be clarified with the customer (approx. 30 miles). b) Select a suitable route so speeds of approximately 65 MPH can be achieved. c) If the vehicle is an AMG P3 Hybrid, switch off

  Summary

  Complaint Consistently reproducible erroneous parktronic warnings from front with every key cycle. Cause The parking sensors are detecting the front brush guard. Remedy Complaint must be consistently reproducible and can occur multiple times a key cycle without obvious cause. NOTE: The parking system serves solely as an aid. Please review both the system function and system limitations as shown in the Operator's Manual. Certain environmental factors can affect system functionality such as hot exhaust gases or extreme heat, sensor interference, or other outside influences or aftermarket modifications. If after verifying the complaint is consistently reproducible: 1. Determine if the complaint is reproducible only in high ambient temperatures. If complaint does not occur in cooler ambient temperatures, it is due to system limitations. You may proceed with the below work but the vehicle may be released afterwards as it is due to system limitations. 2. Remove the brush guard and verify the park distance sensors function as expected. 3. Reinstall brush guard and adjust so that it is as far away from the park sensors as possible. This typically means moving the bar further away at the bottom and closer at the top. 4. Check function. If the concern is still consistently reproducible, please apply clear matte film to the locations as shown below at a minimum, although the clear matte film may be applied to the whole brush guard. Picture: Above shown is the 465 brush guard variant. Although similar to the 463, there are some key differences such as the 465 being fitted with a front camera.

  Summary

  Dear Mercedes-Benz Owner: In our continuing efforts to ensure the proper performance of Mercedes-Benz products and to enhance the satisfaction of our customers, Mercedes-Benz USA is extending the warranty coverage for the Diagnostic Module for Tank Leakage Detection ("DMTL") 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). This applies to the vehicle regardless of ownership. Why the Warranty extension? On certain Model Year 2018 - 2024 A / C / CLA / CLS / E / G / GLA / GLB / GLC / GLE / GLS / GT / S / SL Mercedes-Benz vehicles, under certain circumstances, the DMTL may trigger erroneous Diagnostic Trouble Code ("DTC") entries that may result in the illumination of the Check Engine Malfunction Indicator Lamp ("MIL"). 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 covered under this extended warranty and 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.

  Summary

  Complaint When disconnecting or connecting the charging connector, the charging socket flashes red and red warning messages are displayed in the instrument cluster. Immediately after that, neither driving nor charging is possible. Cause P292900: If the charging cable connector is removed approximately 5 to 7 seconds after the charging process has ended, a fault is triggered. Remedy If this fault occurs, please follow these steps: 1) Wait for bus idle -> driving should be possible again. Note: Charging is still not possible. The fault will keep recurring as long as the fault is stored in the fault memory. 2) Plug in charging cable and check if fault (P292900 or P0AE173) is active. Clear active fault. Charging should be possible after the fault has been cleared. To prevent the fault from recurring, after the charging process has ended, wait at least 15 seconds before disconnecting the AC charging cable connector. Please create a TIPS case including quick test and HV control module log.

  Summary

  Complaint This document is intended as a pre-case diagnostic reference for transmission related concerns. It will also ensure that if a case is necessary, all supporting documentation is available. This should not be used on its own as justification for creating a TIPS case. Cause The root cause will vary depending on the complaint. The goal of this document is to provide diagnostic checks and procedures that may help resolve customer complaints without opening a TIPS case. Remedy Before opening a transmission-related TIPS case, the following steps must be performed to ensure all relevant data has been collected and possible remedies (when applicable) have been performed. Please Note: At minimum, the documents below must be collected before proceeding to ensure the data in its original state when the vehicle arrived is captured. - Initial Quick Test w/ Freeze frame data - VGS Control Unit Log - Initial EEPROM data (.txt format) - IPR Result (if applicable. See LI27.00-P-073124 - Transmission diagnosis using the Intelligent Predictive Repair (IPR) tool) - Transmission Heath Page If the vehicle has previously been repaired for the same concern, note the date, mileage, and TIPS case or RO number, along with a brief description of the prior work performed. IPR Guidance: The IPR recommended repair should be completed prior to following any steps in this LI and prior to case creation. IPR repairs do not require additional warranty approvals or a TIPS case to validate/confirm the results. To ensure efficient case handling, please avoid opening TIPS cases for this reason. For further information regarding IPR please see the following documents: LI27.00-P-073124 - Transmission diagnosis using the Intelligent Predictive Repair (IPR) tool Oil Pan Condition Evaluation: In some situations, IPR will advise checking the oil pan condition and determining a repair based on the evaluation. Example photos in Xentry can be found in two ways: • Use the blue hyperlink in the IPR result, and it will take you to the Condition check of transmission oil • Navigate to Xentry Bluebook > Help for control unit > Condition check of transmission oil If a different repair that what is recommended by IPR is performed, attaching photo documentation of the complaint vehicle oil pan and the IPR example to the claim is required. Reproducing the Concern: Proper evaluation of transmission concerns generally requires the condition to be reproducible. It is recommended to compare the vehicle to a similar model, if available, to help determine whether the shift behavior is characteristic of the drivetrain or uncharacteristic for the vehicle. If the concern cannot be duplicated: • A test drive with the customer may assist in understanding and reproducing the complaint. • The vehicle shift quality should be compared to a known-good vehicle with identical drivetrain and model year. • Check Shift Quality History (VGS Control Unit > Adaptations > Shift Quality History) Shift Quality History will show the last 5 noticeable harsh shifts and some of the parameters in which it occurred. You can use this to attempt recreation of the operating conditions and increase likelihood of reproducing the complaint. Complaint A: Shift Quality Note: Certain AMG variants may exhibit more firm and noticeable shift behavior as a normal characteristic. Refer to LI27.60‑P‑075147 for additional information. 1. Perform Valve flushing procedure 2. Perform 5 Torque Converter adaptions in a row - Allow the vehicle to warm up naturally, DO NOT power brake as it will increase the temperature in the torque converter. - After the 5th adaptation, collect a screen shot showing all 5 on one page 3. Perform a standstill adaption - collect a screen shot Recheck vehicle operation. If the concern has not improved, driving adaptations should be performed to target specific gear shifts.
