It may be due to dust entering the extension mechanism, increasing resistance and preventing the rearview mirror from opening. You can try assisting by hand to see if it resolves the issue. You can ask someone to help operate the rearview mirror switch inside the car while placing your hand on the mirror to feel if the motor inside is working.

I've been driving an Audi A6 for several years and once encountered the embarrassing situation where the electric mirrors wouldn't open. Most likely, it's a blown fuse. The fuse box in Audis is usually located in the small drawer on the left side of the driver's seat or in the engine compartment. You can first check if there's a 15A or 20A fuse that's blown. Replacing it is simple and costs just a few bucks. If the fuse is fine, it might be a faulty switch—try repeatedly pressing the electric folding button, as sometimes poor contact can be restored. Wiring issues are also common, especially in older cars where rainwater seepage causes short circuits. That time, I went straight to the dealership, and after inspection, the technician replaced a small switch to fix it. Remember, forcing the mirrors open while driving can damage the motor—it's better to temporarily rely on the small mirror inside the car. Regular cleaning of the mirror joints can prevent issues, so don't be lazy!

Don't panic if the rearview mirror won't open – troubleshoot it yourself to save time. First, try manually pressing the folding switch: No motor sound? The fuse might be blown. Most Audi fuses are located in the box below the glove compartment; pull it out and check if the color has turned black. Second, shake the mirror to see if it can be opened manually – if it's stiff, the gears might be jammed or the motor could be dead. Third, check if the wiring connector is loose; the wiring harness inside the engine compartment is prone to aging. I've measured the voltage with a multimeter – the normal reading should be around 12V; anything lower indicates a power supply issue. For those without tools, it's best to park and call Audi customer service to ask about local repair shops. Costs can range from a few hundred to over a thousand, depending on the parts needed. When parking, avoid squeezing into tight spots to protect the folding mechanism.

Safety first! It's extremely dangerous when the rearview mirror of your Audi suddenly fails to open while driving. I once encountered this issue on the highway where the mirror wouldn't fold, obstructing lane-change visibility. Immediately pull over to the emergency lane and turn on hazard lights. Forcing operation may cause electrical circuit damage or worse. Check the manual to locate fuses for temporary fixes; if unsuccessful, call for roadside assistance or visit a repair shop. Common causes: water ingress causing short circuits is frequent in premium vehicles like Audi; switch wear or relay failure. Long-term neglect may lead to other malfunctions like window failures. Always park in open areas to avoid hazards, and develop the good habit of quickly testing mirrors before driving to ensure worry-free journeys.
