Why doesn't the Audi A3's rearview mirror fold when locking the car?

Audi A3's rearview mirror does not fold when locking the car because the fold function is not selected in the vehicle settings. Here is additional information: 1. Function: The Audi A4 has foldable rearview mirrors that can be retracted when passing through narrow sections, improving the vehicle's passability. When the driver leaves the car, the rearview mirrors can also be folded, which not only protects the mirror surface but also reduces parking space, effectively avoiding scratches. 2. Avoid excessive operation: When using the folding function of the rearview mirror, the operation should not be too frequent. If the operation is too frequent or if the car is suddenly unlocked while locking, it may cause the function to enter a thermal protection state, resulting in the function stopping in an intermediate state. It is prohibited to drive the vehicle on open roads with the exterior rearview mirrors folded. Before driving, the left and right exterior rearview mirrors must be unfolded and properly adjusted.

My Audi A3's mirrors weren't folding when locking the car, which I also encountered right after purchase. It took me quite a while to figure out. Turns out you need to enable the auto-folding function from the settings menu. Back then, I pressed the vehicle control option on the center display, found the mirror adjustment section where there's a "Fold mirrors when locking" toggle - just switch it on. If it still doesn't respond, it might be a software bug or stuck motor. A friend of mine fixed his car with a software update. Remember to check settings periodically since configurations vary across model years. My 2019 base model didn't have it enabled by default. To prevent hardware wear from repeated manual folding, just test the settings a few times before locking.

As a tech enthusiast, I'll analyze several common reasons for non-folding mirrors. The Audi A3's auto-folding feature requires manual activation through the MMI system - navigate to Vehicle Settings > Exterior Lighting and ensure the 'Auto Fold' switch is on. If the switch is enabled but non-functional, it could indicate a blown fuse or control module failure. From my experience, first check the key fob's long-press lock button settings (sometimes behavior needs customization), then consider voltage issues like battery aging affecting electronic components. If all else fails, I recommend scanning for trouble codes with a diagnostic tool or checking forums for similar cases - most issues are minor and easily fixed.
