  Summary

  Complaint Combustion engine could no longer be started, only electric driving possible Cause High-voltage belt-driven starter-alternator defective Remedy Requirement: Before carrying out test work, it must be ensured that the person performing the work has successfully completed the required qualification for work on the high-voltage system. Note: In order to check whether the high-voltage belt-driven starter-alternator is defective, 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 defective 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

  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 or eliminate noise from high performance AMG brakes. AMG brakes are designed for performance under high load and in certain scenarios, can emit noise. Some of the scenarios are: • Driving style • Brake pressure and application style (stop-and-go traffic with consistent low brake pressure “riding brakes” where the brakes cannot cool sufficiently between applications). • Ambient temperatures 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 recouperation prior to bedding in brakes. d) Brake the vehicle 15 times with a brake pressure of approx. 30 bar (have the passenger read it out using XENTRY) from 62 MPH to 30 MPH (no emergency stops and no braking in the ESP control range). Maintain a cooling distance of approx. 1 mile between brake application

  Summary

  Complaint Customer complains of oil use, oil leaking or oil smell. Upon inspection oil will be seen at or around the rear of the engine and at the engine/transmission interface. Cause Oil leaking from rear main seal and/or rear main seal plate. Remedy If the rear main seal plate has been previously replaced per the instructions in this LI, open a TIPS case before proceeding. Inspect the rear main seal very carefully. Make sure the seal is not sucked in, rolled, or cut (see pictures in attachments). Confirm the leak location is at the rear main seal and/or rear main seal plate by cleaning the area thoroughly and applying trace powder to the suspected area. Allow the vehicle to run either on a lift or at low speed in a controlled environment (do not attempt at high speed or in wet areas as this will make the results difficult to assess). If the leak is emanating from the seal: replace both air/oil separators. Then clean the bellhousing area completely and test with trace powder again to see if the leak remains. If it doesn't, release the car. If the leak remains pull the rear main seal plate, clean the block mating surface completely and replace the rear main seal plate and rear main seal. When the new seal is installed make sure the sealant path is followed exactly as it is shown per the drawing in the attachments. Apply the sealant to the BLOCK instead of the plate to ensure adequate coverage is attained. After installation lubricate a feeler gauge with oil and run it between the rear main seal and the crank to clear any small debris that may be present and to break any binding or stiction.

  Summary

  Complaint Cracking/clicking noise from underbody when driving slowly (around curves); see attachment. Cause Potential causes: • Assembly of the underfloor paneling with unloaded body (results in tension after compression of vehicle in K0- design level) • Relative movement between front and rear engine compartment lining • Torque loss of the screw connection • Accumulation of stones and dirt Remedy • Screw connection in K0-design level (vehicle sitting on ground on it's own weight) and taking into account the correct screw sequence • Additional screw connection points (minimization of relative movement) • Increase in tightening torque • Integration of spacer rings (reduction of accumulation of stones and dirt) In order to rule out that other component parts may be responsible for the noise, remove the underfloor paneling first. If the noise complaints are NO LONGER present after removal, proceed with underfloor paneling rework. Underfloor paneling rework 1. Order after-sales kit with item number A2326207003 for the rework. 2. After receiving the after-sales kit (A2326207003), check the contents: 22 screws (A0109902604) / 14 rivet nuts (A0009902349) / 4 spacer washers (A2326207203). If the content is complete, start rework in the next step. 3. Disassemble underfloor paneling. If front and rear engine compartment lining are bonded to one another, order new parts (A2326201101, A2326268900). 4. Clean underfloor paneling and integral carrier. 5. Mark four additional screw connection points on the front engine compartment lining (see attachment 1). See appendix 2 for dimensions. 6. Drill holes with d=9 mm on the markings. 7. Screw front and rear engine compartment lining together using the screw connection points already available (see attachment 3). Both linings are therefore aligned to one another. Important: Pay attention to alignment of the elongated holes on the external edges. 8. Drill into the rear engine compartment lining using the four additional holes with d=9 mm (see attachment 4). 9. Disassemble front and rear engine compartment lining. 10. Drill out three existing rivet nuts with d=9 mm (see attachment 5). 11. Insert seven new rivet nuts (A0009902349) (see attachment 6). 12. Drill out seven existing rivet nuts in the integral carrier with d=9 mm (see attachment 7). Caution: Do not damage integral carrier. 13. Remove remaining rivets that have fallen off from the integral carrier using a magnetic tube (see attachment 8). 14. Insert new rivet nuts (A0009902349) in the integral carrier (see attachment 9). 15. Fix four spacer rings (A2326207203) in place using bonding points between underfloor paneling and integral carrier (for position, see attachment 10 and attachment 11). Caution: No adhesive can be applied to the contact areas (risk of torque loss). 16. Install underfloor paneling on vehicle with 16 Nm (observe screw sequence in attachment 12). Important: Use screw item number A0109902604.

  Summary

  Complaint After a software update of HERMES communication module N112/9 has been performed on a gray import vehicle, the message "SOS - Service not activated" is displayed in the instrument cluster. Cause The message "SOS - Service not activated" tells the customer that "over-the-air" registration of the vehicle with the Mercedes Intelligent Cloud is not possible. On a gray import vehicle, this is due to the fact that the SIM card installed in the HERMES communications module cannot dial into the mobile phone network in the importing country. Remedy The only way of avoiding the message in the instrument cluster is to deactivate the HERMES module using the 09o deactivation process after obtaining the customer's consent. After deactivation, the HERMES control unit (N112/9) has the operating status "Inoperative". The message "SOS not ready" appears in the audio/COMAND display (A40/8) and may also appear in the instrument cluster. This display message tells the customer that the emergency call function is not available. In addition, the workshop must attach a label (2 x part number A9078172900 required) to the cover of the emergency call button in the overhead control panel and to the emergency call button itself. Replacing the hardware of the HERMES communication module is not effective.

  Summary

  Complaint Single throttle lift-off clunking noise from the side shaft when moving off (audible at the outboard end). The clunk is heard once when changing from forward to reverse (and vice versa). Note: Sound file in attachment Cause If the complaint is eliminated by experimentally loosening the outboard collar nut (by 1 turn), the problem is due to micromovement in the connection between the wheel bearing inner race and the joint housing of the side shaft. Note: The collar nut must always be replaced after being loosened and must be tightened to the specified torque. Remedy Coat contact surface of side shaft with wheel bearing with Molykote paint. To do this, proceed as follows: 1. Remove outboard side shafts (extract outer joint gearing from wheel hub) 2. Clean contact surface A (see image file in attachment "Outer joint housing before") before coating with Molykote, using "spirit" (free of dust and grease) 3. Coat contact surface A (see image file in attachment "Outer joint housing after") using Molykote and leave to dry for one hour in removed condition 4. Reinstall side shafts
