Complaint Thumping noise on rear axle shock absorber on rough road. Cause Until now the rear axle shock absorber support bushing was only available together with the rear axle shock absorber as a replacement part. In future, the rear axle shock absorber support bushing will be available individually as a replacement part to avoid any unnecessary shock absorber noise. Remedy For noise problems on the rear axle shock absorbers, please always make a noise diagnosis, for example using Chassis Ear to localize any sources of noise on shock absorbers or support bushings. If the noise originates from the upper part of the shock absorbers, it is enough to replace the support bushings. Otherwise the complete shock absorber including support bushing have to be replaced. The modified support bushings must be replaced in pairs the first time so that any mixed installation of old and new is reliably ruled out.

Complaint The result from the XENTRY battery test does not match the current state of the battery. Cause The XENTRY battery tester uses the stored on-board electrical system data in the SAM module to access the health of the 12 volt battery. The XENTRY battery test may not take into account a single discharge event because the SAM cannot record the data if the battery is discharged. Note: A discharged battery does not necessarily need to be replaced. A discharged battery may be recovered with no permanent damage. Remedy Follow guided tests as described.

Complaint The touchpad dimming function does not work and the search lighting is either at maximum brightness or fully off (dependent upon dimming signal). Note: The dimming functions of the instrument cluster and head unit display are not affected and remain fully functional. Cause Touchpad (A105) hardware Remedy The serial numbers of the potentially affected parts can be found in the attached list. The serial number can be found on the touchpad itself or in Vedoc (Vedoc -> control units -> TPAD -> serial number). If the serial number listed in VeDoc or on the part (these numbers should be identical) matches one of the serial numbers in the attachment and the described complaint is present, then the touchpad may be replaced.

Complaint The garage door hand transmitter cannot be initialized with the integrated garage door opener in the inside rearview mirror. Cause 1. The integrated garage door opener (GDO) is not compatible with the opening system installed in the garage. 2. The garage door drive uses a rolling code system. In contrast to the fixed code system, the LED in the mirror in this case flashes green after programming. 3. When the handheld remote control is initialized with the integrated GDO, the distance between the handheld remote control and the GDO is too long or too short. 4. The maximum programming time of the hand transmitter was exceeded. The hand transmitter switches itself off after 10s to 20s. However, the garage door opener needs up to 30s to learn the code. 5. The maximum programming time of the integrated GDO was exceeded. The integrated GDO has aborted programming unsuccessfully. 6. The GDO cannot be programmed after replacement (See #9). 7. The batteries of the hand transmitter are too weak. 8. A part of the signal was not registered correctly. 9. The GDO is not programmed to US standards. 10. Errors with Chamberlin MyQ, Liftmaster MyQ, or Craftsman AssureLink systems causing loss of synchronization. Remedy Note: The numbering of the remedies refers to the numbering of the causes. 1. Installation of a universal receiver. Order via the Homelink Hotline. 2. In the case of garage door drives with rolling code system, synchronization of the garage door drive must also be performed. 3. Keep the correct distance when initializing! This can vary between 5 and 20 cm depending on the system. If the initialization attempt is unsuccessful, repeat the initialization process, changing the distance between the hand transmitter and the mirror.

Complaint The range of the integrated garage door opener (GTO) is too short. Cause 1. Vehicles equipped with infrared windows and/or a heated windshield may suffer from complaints involving low transmission power. 2. When comparing the range between the integrated GTO and the garage door hand transmitter, the garage door hand transmitter is tested outside the vehicle. 3. The garage door hand transmitter is being aimed towards the garage door, but the vehicle is in a different position. 4. The garage door drive is old. Remedy 1. The lower level of transmission power is mainly perceived by customers who did not have any infrared windows (code 595) or all-round infrared windows (code 596) or heated windshield (code 597) in their previous model or who have another model without this special equipment in their fleet. The loss in transmission has technical reasons, i.e. a thin metal film is fitted in the windows. Please consider these codes and advise the customer accordingly! Replacing parts does not remedy the problem. 2. Perform the comparison test between the integrated GDO and the garage door hand transmitter under identical conditions. The garage door hand transmitter must be inside the vehicle and must be held at the height of the inside rearview mirror. 3. The customer instinctively aims the garage door hand transmitter towards the door. However, the transmission direction of the integrated GDO depends on the position of the inside rearview mirror, and thus depends directly on the position of the vehicle relative to the receiving antenna of the garage door drive.

This NCU replaces the prior NCU issued on July 30, 2021 and includes an additional population (33) of certain MY 2018 Baumusters covered under this extended warranty. Mercedes-Benz AG (“MBAG”), the manufacturer of Mercedes-Benz vehicles, has extended the warranty on the low pressure fuel hose that connects to the high pressure fuel pump, from the original New Vehicle Limited Warranty of 4 years/50,000 miles to 10 years/120,000 miles (whichever occurs first) on certain Model Year (“MY”) 2015-2018* vehicles. This warranty extension includes the replacement of the fuel hose due to potential fuel weeping on the fuel hose at the inlet connection to the high pressure fuel pump. Under certain cold ambient conditions during a cold start of the engine, the low pressure fuel hose at that connection may experience slight fuel weeping. A brief odor maybe perceptible by the occupants, but a safety risk, including the risk of fire, can be ruled out. This extended limited warranty applies to all aforementioned conditions that necessitate the servicing and / or replacement of the fuel hose under the standard warranty terms and conditions. The extended warranty is applicable to the following vehicles, which are flagged on a VIN-level basis in NetStar:

Lamp unit fogged or droplets forming. Due to the vent openings, the lamp unit is an "open system". This means that acidic gases, moisture, dirt and exhaust gases can penetrate it. This can result in deposits on the diffuser and lens. Check housing cover of lamp unit for natural fogging or dew as per GI82.10-P-009047. . 1. If a reduction in the degree of fogging is visible, the desiccant packs can be used once the condensation has completely evaporated. 1.1. Order the required service covers by referring to the variant overview. 1.2. Remove lamp unit 1.3. Remove all grommets from vent openings. 1.4. Seal vent openings with sealing profile. Important: All openings must be sealed carefully for the pressure compensation membrane to work properly! 1.5. Remove existing service cover 1.6. Place desiccant packs in new service covers and bolt down 1.7. Stick new diaphragm onto specified surface on service cover [picture of service cover] Note: The bonding surface must be clean and dry. 06
