  Summary

  Complaint Rear lamps fogged up/not leaktight. Cause Fogging of the rear lamps is a natural phenomenon, which can occur under certain climatic conditions. This does not lead to any technical impairment of the rear lamps. Remedy Rear lamp: Remedy 1: Clearing fogged/condensed rear lamps: 1. Drive the vehicle into the workshop (temperature higher than +18 °C/+64.4 °F) Note: Do not wash the vehicle or subject it to high-pressure cleaning before the defogging test. 2. Switch off the engine and connect battery support via a charger. 3. Open the trunk. 4. Switch on the exterior lighting. 5. Leave the vehicle in this state for 60 minutes. 6. Check for formation of condensation -> a significant reduction in the formation of condensation must be clearly recognizable (defogging progress). Note: -If no reduction in the degree of fogging is visible, the rear lamp is defective and must be replaced. -It is not physically possible to defog the headlamps completely – some residual fogging may remain. Fogging does not impair the functionality or the service life of the rear lamps. -Simultaneous fogging of multiple component parts indicates extreme climatic conditions and also does not impair the functionality or the service life of the rear lamps. Remedy 2: You can recognize a defective rear lamp as follows: 1. Check the rear lamps to ensure that no external damage is present, and that the differential aeration cells and the diaphragm are present and correctly seated. -> If there are signs of external damage on the rear lamp, the component parts must be replaced as per WIS instructions. 2. Check the electrical connectors of the plugs and pins. -> If moisture/corrosion/etc. is present, the component part must be replaced as per WIS instructions. 3. Check for leak tightness -> Close all openings with Terostat IX or similar and establish and stabilize via an overpressure (40–50 mbar) via the plug. -> In the event of a sudden pressure drop, the component part must be replaced as per WIS instructions. Note: External damage to the rear lamps does not constitute a warranty or goodwill case.

  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

  Summary

  Complaint Noises/ squealing from the service brake in various driving situations and ambient conditions Cause Frictional vibrations Remedy AMG brake systems are designed for high loads. This can result in noises under certain operating conditions. These are dependent on speed, brake pressure or ambient conditions such as temperature and air humidity. (Extract from the owner's manual) If customer complaints are received, please proceed as follows: • Check whether, apart from this document, an additional document exists for the model series in question, and if so, work through it • Check whether the complaint can be reproduced and at which axle the noises occur (ideally together with the customer while driving) • Check the friction pairings of the affected axle for wear, mechanical damage or localized overheating damage. a) If this is the case, replace the damaged component parts and assess the brake again with regard to noise. b) If there no obvious visible or technical problems with the brake system, we recommend bedding in the brakes by following the procedure below: • Before trip, the mileage incurred must be clarified with the customer (approx. 50 km) • Select a suitable route • Brake the vehicle 15 times with a brake pressure of approx. 30 bar (have the passenger read it out using XENTRY) from 100 km/h to 50 km/h (no emergency stops and no braking in the ESP control range). Maintain a cooling distance of approx. 1.5 km between brake applications • Finally drive approx. 5 km to allow the system to cool • Reassess the problem If this action fails to deliver the desired success, create a TIPS case with the following information: • Observe SI00.00-P-0086A • Have parts already been replaced? If yes, when and which parts (date, mileage)? • How is the customer's driving profile, and when/where is it reproducible? • Create a video/ sound file • Attach usable pictures of the brake components on the affected axle (important: including the back of the lining)

  Summary

  Complaint Headlamps fogged or droplets forming. Cause Due to its outlet openings, the headlamp is an "open system". This means that acidic gases, moisture, dirt and exhaust gases can penetrate into the headlamp. This can lead to the formation of condensation on the lens of the headlamp. The headlamps comply with all applicable US standards and regulations. Remedy Check housing cover of lamp unit for natural fogging or condensation as per LI82.10-P-078301. If a reduction in the degree of fogging is visible, the desiccant packs can be used once the condensation has completely evaporated. Note: Order service covers and desiccant packs based on the validity description. 1. Remove headlamps. 2. Remove all grommets from outlet openings. 3. Seal vent openings with sealing profile. Important: All openings must be sealed carefully for the pressure compensation diaphragm to work properly! 4. Remove existing service cover. 5. Place desiccant packs into the new service covers and bolt down (Picture_01). 6. Glue the new diaphragm onto the intended surface at the service cover (Picture_02). Note: The bonding surface must be clean and dry. 7. Attach service cover with desiccant pack at headlamp. 8. Install headlamp. To ensure that the desiccant pack (absorption) acts effectively, the headlamp has to be air-sealed. Observe or check the following points for this: 1. Seals at the central connector must all be present and correctly fitted (Picture_03). 2. The new transparent diaphragm must be correctly bonded (Picture_04). 3. Check headlamp housing for any external damage.

  Summary

  Complaint Headlamp or front fog lamp leaky or fogged Cause Fogging of the headlamps is a natural phenomenon, which can occur under certain climatic conditions. It does not lead to any technical impairment of the headlamp. Headlamps comply with all applicable standards. If a pressure compensation diaphragm is fitted in the housing cover, then the lamp unit is a "closed system". Remedy Headlamp: Remedy 1 Clearing fogged/condensed LED headlamps and LED rear lamps: 1. Drive vehicle into workshop (temperature higher than +18 °C/+64.4 °F) and connect the exhaust extraction. Note: Do not perform an engine wash before the defogging test. 2. Switch off the engine and connect battery support via a charger. 3. Open the hood or trunk. 4. Switch on the lights. 5. Leave the vehicle in this state for 60 minutes. 6. Check for formation of condensation, a significant reduction in the formation of condensation must be clearly recognizable (thawing progress). Clearing fogged/condensed halogen/xenon headlamps: 1. Drive the vehicle into the workshop (temperature higher than +18 °C/+64.4°F). Note: Do not perform an engine wash before the defogging test. 2. Switch off the engine. 3. Open the hood. 4. Switch off the lights. 5. Leave the vehicle in this state for 60 minutes. 6. Check for formation of condensation, a significant reduction in the formation of condensation must be clearly recognizable (thawing progress). Note: If there is no visible reduction in the formation of condensation, check the headlamp for a defect. (See Remedy 2) It is not physically possible to defog the headlamps completely. Fogging does not impair the operation or the service life of the headlamp. Remedy 2 A Damaged headlamp can be identified as follows: 1. Check the headlamp for external damage and that the cover caps and the diaphragm are correctly seated. 2. Check the electrical connectors of the plugs and pins. 3. Check for leak tightness in accordance with LI82.10-P-078307. The test can only be conducted on headlamps. 4. If the headlamp or the rear lamp has any external damage, replace the component part in accordance with the WIS instructions. Note: External damage to the headlamp/rear lamp or faulty seating of the cover caps does not present a warranty or goodwill case. With headlamps, it is possible to install desiccant packs if the problem occurs repeatedly. Open ventilation system: LI82.10-P-064766. Closed ventilation system LI82.10-P-078304

  Summary

  Complaint Damage or discoloration to paint protection films on vehicle. Cause Chip protection films are a wear item that may need to be replaced over the life of the vehicle. They are typically not covered by vehicle warranty. Remedy To properly install a paint/chip protection film, please follow the below guidelines: #1 - Utilize a solution that is 0.2% soap solution (1,000ml of water + 2ml of liquid soap). #2 - Clean the paint surface and ensure it is dust-free. #2a - When cleaning, you can utilize isopropyl alcohol (Rubbing Alcohol) to assist with cleaning. #2b - We recommend a lint-free rag for secondary dusting. #3 - Wet hands with the soapy water solution to protect the adhesive surface. #4 - Remove the backing paper from the film completely. #5 - Moisten the vehicle surface with the soapy water. You can also lay the protective film with adhesive side out onto the wetted surface to also cover the adhesive layer in the soapy water solution. #6 - Remove film and flip over to gently place adhesive side against the paint surface. #7 - Working from the center out, use a squeegee to press the soapy water solution out from under the film. Use sufficient pressure to firmly press the film into the paint surface, but not an excessive amount to damage or stretch the film. #8 - Allow film and paint to "cure" until all of the moisture has evaporated. At this time the adhesive should be dried and cured enough for sufficient hold to release the vehicle.

  Summary

  Complaint Headlamps fogged or droplets forming. Cause Due to the housing cover with pressure compensation diaphragm, the headlamps are a "closed system". This means that the headlamps are protected against acid gases, dirt and exhaust gas. However, moisture can still enter from two sources. Through absorption and desorption (the commonest cause) or through permeation. Moisture is either absorbed by the plastic material and, when the light source is switched on, it is released from the plastic by desorption, or the moisture penetrates through the plastic materials of the headlamp from outside (permeation). This can lead to the formation of condensation on the lens of the headlamp. The headlamps comply with all applicable US standards and regulations. Remedy Check headlamps for natural fogging or condensation as per LI82.10-P-078301. If a reduction in the degree of fogging is visible, the desiccant packs can be used once the condensation has completely evaporated. Note: Order service covers and desiccant packs based on the validity description. 1. Remove existing service cover with diaphragm (Picture_01 (1)). 2. Insert desiccant packs (Picture_01 (2)) into new service covers with diaphragm and seal with protective grille and bolt down (Picture_01 (3)). Note: One desiccant pack is required for each small service cover, and two desiccant packs are required for each large service cover. 3. Stick the supplied diaphragm onto the new service cover and attach at the headlamp. Note: The bonding surface must be clean and dry. 4. If the headlamp housing has an additional 2nd diaphragm, this must be covered over with masking tape. Note: The bonding surface must be clean and dry. To ensure that the desiccant pack (absorption) acts effectively, the headlamp has to be air-sealed. Observe or check the following points for this: 1. Seals at the central connector must all be present and correctly fitted (Picture_02). 2. The new transparent diaphragm must be correctly bonded (Picture_03). 3. Check headlamp housing for any external damage.

  Summary

  Complaint To insure vehicle down time is kept at a minimum and all required information is available when case is escalated, as well as assist technicians with checks that may help lead in resolving issue without case creation. THIS LI IS NOT TO BE USED AS A REASON FOR CASE CREATION BUT AS A GUIDE IF A CASE IS NEEDED Cause There are, at times, additional steps workshops can do to help diagnose and rectify transmission complaints. Remedy When opening a case for transmissions a EEPROM, Quick Test, and VGS CUL are absolutely necessary Please also check for any relevant LI’s before opening case. Also, recommend having customer fill out Transmission Drivability Diagnostic Worksheet especially if complaint is hard to reproduce or intermittent (Work sheet Location: Xentry Portal >> Local Contents >> Diagnostic Info>> Diagnostic Worksheets ) If a previous repair attempt or visit was made for the same concern please include the date, mileage, and case number if applicable of that repair/visit with a short description of what was done. Follow IPR: ( LI27.00-P-073124 ) All IPR suggestions are covered by warranty and there is no need for cases to confirm IPR. Complete IPR suggestions and close out IPR process. If complaint is not fixed and IPR still suggests the same repair once closed out and run again, then a case may be needed. Transmission Health page is a good indicator of issues within transmission if clutch or brake pack stays NOK after adaptions and unable to be made to a green OK then an internal fault is present. Proceed with replacing affected clutch pack. IF more than 3 are red and NOK replace transmission (include printout with warranty claims) **** FOR 167 chassis with M264 engine B08 may be red and NOK, IGNORE this, B08 is still okay **** Shift complaints: Note: AMG variants are known to have a harsher shift see LI27.60-P-075147 It is always worth comparing to a like vehicle if possible to see if shift is uncharacteristic Perform Valve flushing procedure Perform 5 Torque Converter adaptions in a row (Save the results page) Perform standstill adaptions (Save the results page) Drive adaptions if necessary: Drive C mode keep RPM between 2000-2200rpm and lightly let off pedal to force shift wait 2-3 sec then roll on throttle to rpm back up to 2000-2300 rpm repeat for gears 1-3 *For gears 4-8 allow rpm up to 2700 and let off slightly to force upshift = repeat x 10 *For downshift - highest gear possible 8 or 9 - allow decel with light brake drag (allow at least 5s between downshifts for trans to adapt. Go down to 2nd and repeat x10 *Change to sport mode and repeat process again *Lock car to allow sleep at least 10min and restart and road test for quality. After adaptions a new EEPROM should be recorded and included with the original if opening a case Understand shift complaints need to be reproducible to address. If needed drive with client to reproduce the complaint. If shift complaint is intermittent a CAN trace of the issue occurring will be useful (see attached instructions) Shudder: If there is a shudder monitor torque convertor actual values to see if it occurs during slipping, Additionally can lock up convertor and drive to see if issue is resolved Jolting/Shudder: If the vehicle is AWD: unplug AWD control unit or drive vehicle in dyno mode to see if transfer case is causing the jolt/ harsh shift If located from transfer case check fluid and perform a flush if needed to try to rectify the issue. Vibrations: NVH trace is needed, what level vibration is being experienced and where is it located? Is the Vibration felt in neutral? Dyno mode? Does it change with speed? Etc. Noise complaint: Isolate the noise location using chassis ear. MUST attach a sound recording or video of the noise. Describe when the noise is present: Does it change with gear or speed? Does it occur with vehicle in neutral or in glide mode? Does operating temperature effect noise? Does incline/decline or steering angel effect noise?
