M3401132018-11-26. Service bulletin. SERVICE BRAKES, HYDRAULIC. Erroneous "Service due" Message Though Brake Lining Thickness Sufficient. The CBS data calculated for the remaining distance of the front and/or rear brake pads does not agree with the actual brake pad thickness. The yellow brake lining service due indicator illuminates even though the pad thickness is greater than the minimum wear limit (approximately 3.7 mm); the brake wear sensor has not yet been activated (from a thickness of approx. 4.2 mm). In some cases, the red warning message may already be active. The CBS front/rear brake display is based on a mathematical calculation. Various influences are incorporated into this calculation (for example, vehicle speed, brake pressure, and rotor temperature). Due to changing driving characteristics and/or unfavorable environmental conditions, the calculated remaining distance may differ from actual pad thickness.

M6504142018-11-13. Service bulletin. ELECTRICAL SYSTEM; EQUIPMENT ADAPTIVE/MOBILITY; EQUIPMENT. Automated Activation of Navigation System During PDI/QC1. INFORMATION Important: The INITIAL NAV enabling code no longer needs to be pre-ordered through the Parts department! When the vehicle is connected to the diagnostic system ISTA to perform PDI/QC1, the step to activate the navigation system (part of Delete Transport Mode) will automatically request the INITIAL NAV enabling code (VIN-specific) without pre-ordering the enabling code. This enabling code will be automatically delivered through ISTA and it then activates the navigation system. Note: This VIN-specific NAV enabling code is then also automatically stored in the Repair Kit in the Aftersales Assistance Portal (ASAP). The automated INITIAL NAV enabling code request and activation of the navigation system will take no longer than 1 minute. After finishing "Delete Transport Mode," the navigation system in the vehicle will be active without entering the 20-digit INITIAL NAV enabling code manually or in ISTA. If the navigation system is not active and asking for the enabling code, turn off the ignition and wait for the head unit to enter sleep mode (approx. 3 minutes). After that, turn on the ignition again. The head unit will start up and the navigation system is activated. If the INITIAL NAV enabling code for first-time activation of the navigation system is not requested or delivered automatically, it still can be ordered manually through the Parts department and activated in the vehicle by entering the 20-digit enabling code manually.
