What are the reasons for the unavailability of Volkswagen's parking brake function?

The reasons for the unavailability of Volkswagen's parking brake function are: 1. Radar probe failure; 2. Control module failure; 3. Wiring failure. The method of using the parking function is: 1. Keep the speed below 30 kilometers per hour; 2. Press the intelligent parking button on the panel next to the driver's seat, and the vehicle will automatically search for nearby parking spaces. After the central control screen displays the parking space information, select confirm, then choose forward or reverse based on the position, engage the gear, and adjust the position to park. Volkswagen's models include: Magotan, Sagitar, Golf, Tiguan L, Tayron, Phideon, etc. Taking the 2021 Golf as an example, it belongs to the compact car category, with body dimensions of: length 4296mm, width 1788mm, height 1471mm, wheelbase of 2636mm, fuel tank capacity of 51 liters, and trunk capacity of 380 liters.

I recently encountered the issue of the Volkswagen parking brake function showing as unavailable. It might be due to sensors being clogged with dust or mud, or there could be short circuits or open circuits in the electrical wiring. Blown fuses are also a common cause, especially when excessive current causes them to melt. On the software side, sometimes the control system needs an update or reset—in my case, restarting the vehicle didn’t help. Low battery voltage can also trigger this fault warning. For safety, never park on a slope; manually engaging the traditional handbrake is more reliable. When I took my car for repairs, I found that the sensor connector was loose—reconnecting it firmly fixed the issue. I recommend regularly cleaning the parking radar, especially during the rainy season when moisture can cause problems. In short, don’t delay addressing this issue—visit a professional shop promptly to avoid accidents, as driving safety always comes first.

As someone who often tinkers with cars, I've dealt with parking brake failures several times. First step is checking if any fuses are blown - consult the manual for their locations. Then inspect sensors for dirt obstruction; sometimes a water rinse helps. For software glitches, restarting the engine or system updates might work. Control module failures require diagnostic tools to scan error codes. Once I had a failure due to low-temperature component malfunction - replacing the module myself took time. Remember to manually engage the handbrake as backup when parking on slopes, don't rely solely on automatic functions. Preventive maintenance is crucial - regularly clean radar areas and prevent water accumulation that could corrode wiring. It's always better than emergency repairs.

Encountering a parking brake malfunction, I recalled my last car repair experience. Most likely, it's caused by dirty sensors leading to signal interruption or module hardware issues. Circuit problems like blown fuses or loose wiring harnesses are also common. Safety first, use the traditional handbrake to secure the vehicle. It's recommended to visit a repair shop for an OBD scan to pinpoint the cause. Maintaining battery health regularly can help reduce similar issues.
