  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 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

  Mercedes-Benz AG ("MBAG"), the manufacturer of Mercedes-Benz vehicles, has determined that on certain Model Year (“MY”) 2012-2016 E-Class, GL-Class, GLE-Class, GLK-Class, and ML-Class (166, 204, 212 platforms) vehicles, the coding of the control units for selective catalytic reduction (SCR) and fully integrated transmission control (VGS) do not correspond to the specifications as part of the “BlueTEC update” diesel field measure. This could result in the CAL ID (Calibration ID) not being read out from the vehicle and re-documented in the relevant systems. This situation does not have any additional technical implications for the vehicle. What We’re Doing MBUSA will conduct an Emission Service Campaign in which an authorized Mercedes-Benz dealer will update the SCN coding for SCR and VGS on the affected vehicles.

  Summary

  Mercedes-Benz AG ("MBAG"), the manufacturer of Mercedes-Benz vehicles, has determined that on certain Model Year (“MY”) 2013-2016 E/GLK/GLE/M-Class vehicles, the software for the water pump diagnostics may not correspond to current specifications. This issue has an extremely low rate of occurrence in the field and has no known emissions or fuel economy impact. However, in the rare instance this issue does occur in a vehicle, it may prevent the vehicle from passing certain state inspection requirements (e.g., California SMOG check). What We’re Doing MBUSA will conduct an Emission Service Campaign in which an authorized Mercedes-Benz dealer will update the software for the water pump diagnostics on the affected vehicles.
