- [A451206 2031989\-](/bulletins/10122679.md), 2017-11-08, Service bulletin: EXTERIOR LIGHTING:BRAKE LIGHTS; EXTERIOR LIGHTING:BRAKE LIGHTS:SWITCH. After replacing the ABS control unit, the new control unit stores DTC 01044 \(Control Unit Incorrectly Coded\). No warning light is on and the brake electronics work correctly. Due to a supersession of parts, only ABS/ESP hydraulic control units prepared for vehicles equipped with the start\-stop feature are supplied as replacement parts. Once installed, the new unit stores DTC 01044 \(Control Unit Incorrectly Coded\) because it does not receive a response on the data bus when checking for the start\-stop feature. The missing response results in the DTC entry. Within the scenario described in the Condition section of this TSB, the missing start\-stop response is the only reason for this DTC. In all other respects the coding of the ABS/ESP control unit matches the vehicle data. The entry does not affect the function of the brake electronics and no warning appears in the instrument cluster. There are no effects on performance or safety.
- [A941200 2024877\-](/bulletins/10122672.md), 2017-11-08, Service bulletin: EQUIPMENT; ELECTRICAL SYSTEM; EXTERIOR LIGHTING:HEADLIGHTS. Supersedes Technical Service Bulletin Group 94 number 12\-83 dated July 9, 2012. Warning light for dynamic headlight range control is displayed in the instrument cluster. DTC 00003 / 14 \(Control unit faulty\) is registered in the dynamic headlight range control unit, address word 55. Both headlights function normally. Vehicles equipped with adaptive \(cornering\) lighting. New software version 0010 in the dynamic headlight range control module addresses this condition. If the headlight range control module has a software version lower than 0010 installed, then use the SVM code listed in Service to update the module. Some control units will already have software version 0010 installed but can still exhibit the conditions mentioned above. When this occurs, the software will need to be reflashed using a separate SVM code. The corrupt software will be overwritten. The software version does not change after the update.
