故障1 一辆行驶8万km的奥迪A8 2.8轿车,驾驶员反映变速器手动模式Tiptronic功能失效。试车检查,发现当换挡杆由“D”位移入Tiptronic挡位时,仪表板上的挡位显示不变化,换挡杆向前(+)和向后(-)推时车速无变化。正常情况下,仪表挡位显示应由“P R D 4 3 2”变为“5 4 3 2 1”。且随着发动机的转速变化,换挡杆向前(+)、向后(-)推时车速应随之上升或下降。使用V.A.G1551进行变速器系统自诊断,检测发现一个故障码:18152
Fault 1 An Audi A8 2.8 sedan driving 80,000 km, the driver notifying the transmission manual mode that the Tiptronic function failed. When the shift lever was moved from the “D” position to the Tiptronic position, the gear display on the instrument panel did not change and the vehicle speed did not change when the shift lever was pushed forward (+) and backward (-) . Normally, the meter display should change from “P R D 4 3 2 ” to “5 4 3 2 1 ”. And as the engine speed changes, the shift lever forward (+), backward (-) when the vehicle speed should rise or fall. The use of V.A.G1551 transmission system self-diagnosis, testing found a fault code: 18152
