SummaryComplaint 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.

SummaryComplaint 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?

SummaryComplaint Combustion engine can no longer be started, only electric driving possible Cause High-voltage belt-driven starter-alternator has a failure 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 has a failure, 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 has a failure. In this case, the high-voltage battery must be replaced after the short circuit has been eliminated. (See attachment) The faulty component 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 failure. 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 small or 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 approved tools and equipment.
