Electric folding function failure of the exterior rearview mirrors, excluding mechanical and electronic control reasons, commonly encountered causes for electric folding function failure mainly include two aspects: 1. The battery is disconnected or dead: In this case, the exterior rearview mirrors must be reset to function properly. 2. After setting "fold the rearview mirrors when locking the car," manual folding was performed: In this case, the next time the vehicle is unlocked, the exterior rearview mirrors will not automatically unfold. You need to enter the vehicle and press the button on the door to manually unfold the exterior rearview mirrors. Additional information: When driving, you need to "keep your eyes and ears open." On one hand, you must concentrate on observing the dynamics ahead; on the other hand, you must use your peripheral vision to observe the left, right, and rear conditions of the vehicle through the car rearview mirrors. Only by comprehensively collecting information from all aspects can driving safety be ensured. Observing the situation ahead is relatively convenient, while the left, right, and rear conditions must rely on the car rearview mirrors.
I found that the Audi A4L's side mirrors cannot automatically retract, and there are several common reasons for this. First, it could be a malfunction of the mirror motor. Over time, the motor may burn out or get stuck, such as due to dust or water ingress causing operational issues. Second, the control switch might be damaged, where poor contact in the door handle or center console button interrupts the signal. Third, it might be a blown fuse—check the relevant fuse in the fuse box to see if it's burned out. Fourth, it could be a system setting issue, where some owners accidentally disable the automatic function in the vehicle's menu. Fifth, wiring aging, loose or damaged wire connections can cause intermittent current flow. It's recommended to first try manually operating the switch a few times to rule out setting errors. If that doesn't work, consult a professional technician to inspect with tools, as delaying may affect driving convenience.
