- Power train
When the vehicle is in drive and you open the door it shifts to park. However, if the vehicle is in drive and you turn it off, the vehicle shifts to NEUTRAL. This causes the vehicle to roll with the engine off.
- Steering
I park at the Mall and after two hours, start the car again to go home the front panel shows "Power Steering Malfunction See owners manual" and the steering has not assistance which makes hard to drive. The steering is hard to maneuver.
- Power train · Vehicle speed control
Sometime when I press on the gas. It does a hard shift gear change. Feel like I got kicked by a horse in the rear. I have changed out front and rear differential gear oil and I changed out the transmission fluid and filter. It still does it. I'm thinking it's something in the ECM or TCM firmware…
Sometime when I press on the gas. It does a hard shift gear change. Feel like I got kicked by a horse in the rear. I have changed out front and rear differential gear oil and I changed out the transmission fluid and filter. It still does it. I'm thinking it's something in the ECM or TCM firmware since the dealer refuse to update the firmware for me. I'm leaning towards a firmware issue since I'm outdated (never been updated).

- 11010907Complaint The flap of the reversing camera opens and closes by itself during forward travel. This happens several times during the trip. The customer notices the sound of opening and closing. No camera image is displayed in the head unit. The reversing camera or the 360 system functions normally when activated manually or by engaging drive range "R". This behavior occurs again during each driving cycle. Cause This is not a malfunction, but an intended system behavior: Calibration of the reversing camera is in progress. For this, the cover on the camera is opened for max. 5 cumulative minutes in forward travel. The calibration can be performed if the vehicle speed is < 35 km/h and the steering wheel angle is < 10 (for early vehicles from MFA2 facelift model series such as A-Class, CLA, etc., the 35 km/h (~22 MPH) opening limit may only be reached after the SCN coding is replaced). If the speed of 35 km/h (~22 MPH) is exceeded, the camera retracts and the calibration is therefore aborted. The sequence is started again once the speed returns to the range of 18 km/h (~11 MPH). Remedy Complete the calibration successfully. For this, the vehicle must be driven forwards for a certain time (usually significantly less than one minute) at a speed < 35 km/h (~22 MPH) and a steering wheel angle < 10. This should occur during daylight and without a vehicle following too closely (the camera must be able to see the asphalt). When calibration is successful, the camera flap closes automatically at an unchanged speed. For the rest of the driving cycle, the camera now only opens if the customer requests this, for example by applying the reverse gear. When starting a new driving cycle (ignition change), another calibration is required. The customer can generally perform calibration at the first attempt when a speed in the range between 15 km/h (~9 MPH) and 35 km/h (~22 MPH) is briefly maintained and can therefore play a significant role in reducing the actuation frequency and therefore also the noticeability of the noise to a minimum. In the case of early MFA2 facelift vehicles (A-Class, CLA, etc.), the parking control unit may have to be SCN-coded again to have the complete speed window available for the calibration.
- 11010818Complaint Transmission control unit Y3/8n4 (fully integrated transmission control unit (VGS)) not listed in quick test and/or no communication possible with VGS. Cause Transmission control unit Y3/8n4 Remedy It is important that LI54.15-P-057373 is processed before replacing any component parts (transmission 722.9). After processing and complying with the above documents, perform a reset on the transmission control unit Y3/8n4 (VGS) (ignition reset), check that the transmission connector is seated correctly and inspect the PINs for concerns. If communication with the VGS cannot be established afterwards, the component part 'electrohydraulic controller unit (EHS)' must be replaced, as it is not possible to transfer the valve characteristics under the above-mentioned conditions. Installation of a VGS repair kit is not permitted in this case.

- 11007974Complaint 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
- 11007790Complaint 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.
- 11007753Complaint 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/+64.4F). 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
- 11007728Complaint 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 LIs 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?
