SummaryComplaint 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.

SummaryComplaint 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.

SummaryComplaint 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.

SummaryComplaint The fault code C112502 is logged (as current or stored) in the rear axle control unit (N68/4). Cause The fault code is caused by communication with the ESP control unit: 1. After carrying out a quick test or performing a diagnosis on the ESP control unit (N30/3): This fault code occurs in the ESP control unit (N30/3) as a result of the diagnosis performed with XENTRY Diagnosis. At the point of diagnosis, the ESP control unit (N30/3) sends the value "ERROR" on the FlexRay. The rear axle steering control unit (N68/4) is not able to process this value and logs the fault code C112502. 2. As a result of a fault code logged in the ESP control unit (N30/3): As a result of the fault code logged in the ESP control unit (N30/3), the ESP control unit (N30/3) sends the value "ERROR" on the FlexRay and the rear axle steering (N68/4) switches to the safe mode provided for this purpose. Remedy Re. cause 1: If fault code C112502 does not occur until after a quick test or after a diagnosis performed directly in the ESP control unit (N30/3), the fault code can be ignored and deleted directly in the rear axle steering control unit (N68/4). If the fault code is current, perform an ignition off/on so that the fault code is only registered as stored. Re. cause 2: If fault code C112502 is already present when the first quick test is carried out, check and process the fault code(s) in the ESP control unit (N30/3). Here too, the fault code can be ignored and deleted directly in the rear axle steering control unit (N68/4).
