A531302 2034404-2017-12-05. Service bulletin. ELECTRICAL SYSTEM; PARKING BRAKE. Customer may report that the vehicle does not start due to a discharged battery. DTC U101100 (supply voltage too low) is stored in the gateway, J533 (address word 19), and/or the electronic parking brake (EPB) control module, J540 (address word 53). According to the test plan "19-Read Data Bus Keep-Awake Manager", the EPB control module kept the data bus active for prolonged periods of time. The EPB switch appears to be permanently operating (applying or releasing the parking brake) due to an internal mechanical issue or because it is jammed or blocked by debris or by a foreign object. Test plan "19-Read Data Bus Keep-Awake Manager", identifies the EPB control module as keeping the data bus active for prolonged periods of time.

A461347 2034387-2017-12-05. Service bulletin. ELECTRICAL SYSTEM; PARKING BRAKE. Customer may report sporadically hearing the parking brake being actuated after the vehicle has been switched off. If the customer does not identify the sound as the sound of the parking brake being actuated, he or she may simply complain of hearing noises from the rear brakes. Ignition is switched off. Steering is locked. Park is selected. Parking brake is not engaged. If the electro-mechanical parking brake is not operated for some time, the free play between brake pads and brake discs increases because of normal brake pad wear. The parking brake control unit performs an automatic correction about every 621 miles (1,000 km). On A8 models, the brake pad thickness is also calculated.
A461226 2031135-2017-11-08. Service bulletin. LANE DEPARTURE; PARKING BRAKE; ELECTRICAL SYSTEM. The customer may state the yellow warning for electric parking brake (EPB) appeared once in the instrument cluster, but the warning turned OFF after cycling the ignition and there have been no additional occurrences. The customer may state the adaptive cruise control (ACC) was inoperative once, but resumed operating properly after cycling the ignition and there have been no additional occurrences. DTC is stored in the EPB module. Internal code Param_InterFaultID 24 or 25 may be in the extended environmental conditions. The concern is due to a software glitch in the EPB control module. Concerns related to this software glitch can only occur once. Replacing the EPB module may cause an additional occurrence.
