An official CAA Japan notice concerns Passenger cars (Audi Audi Q3 2.0Tq 132kw and others) - Repair. Due to defects in the gateway control unit, onboard supply control unit and four-wheel-drive control unit. ■Defective parts (component names): ①Gateway control unit ②Onboard supply control unit ③Four-wheel-drive control unit. ■Description and cause of the structure, equipment or performance deemed noncompliant with standards: ①Because the software in the gateway control unit that controls brake light illumination is inappropriate, the braking signal is not sent to the body control module when emergency braking is activated, and the brake lights do not illuminate. This does not comply with Article 12 of the Safety Standards (technical requirements of UN Regulation No. 13H). ②On vehicles equipped with LED front lights, the software in the onboard supply control unit that controls the front position lights is inappropriate. When the turn signals and hazard warning lights are operated while the front position lights are illuminated, the front position lights flash. This does not comply with Article 34 of the Safety Standards. ③Because the software in the four-wheel-drive control unit is inappropriate, driving force may not be distributed properly to the rear axle when driving on slippery roads or similar surfaces. As a result, more driving force is distributed to the front axle, which may cause the front wheels to spin. Published 2017-10-18.
What to do now
(Recall) 外-2546 ■Corrective measures: ①Modify the gateway control unit software on all vehicles. ②Modify the onboard supply control unit software on all vehicles. ③Modify the four-wheel-drive control unit software on all vehicles.
