What is the reason why the Mercedes-Benz C-Class's mirrors do not fold when the car is turned off?

The reasons why the Mercedes-Benz C-Class's mirrors do not fold when the car is turned off are: 1. The mirror folding function is turned off in the settings; 2. A door is not properly closed; 3. The engine is not turned off or there is a mechanical or electrical fault. Taking the 2021 Mercedes-Benz C200L as an example, it is a mid-size car with body dimensions of length 4784mm, width 1810mm, height 1457mm, a wheelbase of 2920mm, and a fuel tank capacity of 66L. The 2021 Mercedes-Benz C200L has a multi-link independent front suspension and a multi-link independent rear suspension. It is equipped with a 1.5L turbocharged engine with a maximum horsepower of 156PS, a maximum power of 115kW, and a maximum torque of 250Nm, matched with a 9-speed automatic transmission.
I've been driving a Mercedes-Benz C-Class for three years and encountered an issue last year where the mirrors didn't fold when locking the car. Here's my experience sharing. There are several common causes: First, the auto-folding feature isn't enabled in vehicle settings—check the comfort functions menu in the central control screen to confirm it's activated for locking. Second, the mirror motor might be faulty, as Mercedes motors tend to age after a few years, requiring component replacement. Third, a blown fuse—locate the corresponding one in the engine compartment fuse box and inspect it with a tool. Fourth, poor electrical contact due to oxidation from rain or dust. Fifth, mechanical jamming, like dirt buildup in the pivot area. In my case, gently brushing the mirror joints and rebooting the system resolved it. Regular mirror cleaning prevents blockages, or visit a dealership for professional diagnosis to avoid bigger losses—safety first. Overall, the issue isn’t complex; patient troubleshooting suffices.
The Mercedes-Benz C-Class power-folding mirror malfunction, as a car technology enthusiast, I believe the issue mostly lies in the electrical system. First, check the fuse condition - locate the mirror-specific fuse in the under-dashboard fuse box to see if it's blown. Second, relay failure where contact point erosion causes control failure; motor damage is a common main cause as aging and voltage instability make it vulnerable; wiring aging leading to short circuits or breaks requires multimeter testing; electronic control module software errors can be resolved by resetting the vehicle; aftermarket modifications like added equipment may interfere with the original circuit. For diagnosis, connect OBD to read fault codes for precise localization. Regular maintenance should focus on cleaning contacts and avoiding water ingress. Professional shop repair is recommended to prevent electric shock risks. The key is step-by-step testing from power source to actuator components.
My Mercedes-Benz C180's mirrors didn't fold after locking, which was really annoying. A friend suggested it might be a setting issue: go into the car's system, find the vehicle settings menu, click on comfort functions, and check if the automatic folding option is turned off. If it's on and still not working, check if the switch button is responsive and try folding them manually. A broken motor (expensive to repair) or damp/worn wiring could also be the cause. A simple DIY fix is to wipe the mirror pivot area clean with a dry cloth to remove dust and debris—might help them fold. Don't worry, a 4S shop check usually resolves minor issues.
