运行中的奥迪、桑塔纳等轿车,有时会出现水温报警灯闪亮(水温过高)而风扇不转的故障。若此时正在高速公路或夜间行车,往往使驾驶员不知所措,危及行车安全。 Running Audi, Santana and other cars, sometimes there is a warning light flashing water temperature (water temperature is too high) and the fan does not turn the fault. At this moment, driving on an expressway or at night often overwhelms the driver and jeopardizes traffic safety.
