What Causes the Steering Wheel of a Volkswagen to Lock and Prevent Starting?
2 Answers
Volkswagen's steering wheel locking and preventing the car from starting is due to the activation of the steering wheel lock function, which is part of the car's anti-theft system, preventing the engine from igniting. The steering wheel lock function is a simple anti-theft mechanism. Its principle involves using the rotation of the key to control a steel pin via a spring. Once the key is removed, any movement of the steering wheel causes the steel pin to pop into a pre-drilled hole, locking the steering wheel in place and preventing it from turning. When the steering wheel is locked, it becomes immovable, the key cannot be turned, and the car cannot start, thereby achieving anti-theft. To release the steering wheel lock, simply press the brake pedal, hold the steering wheel with your left hand and gently shake it, while simultaneously turning the key with your right hand. For keyless start models, the procedure is similar: press the brake pedal, turn the steering wheel left and right, and then press the start button to start the car. It is recommended that drivers address the steering wheel lock issue under safe conditions. If the steering wheel locks during driving, immediately stop the car, turn off the engine, disconnect the battery, wait for the car's computer to restart, and then try starting the vehicle again. If the problem persists, professional assistance should be sought.
I've encountered a situation where my Volkswagen's steering wheel was locked and the car wouldn't start, mainly because the steering wheel anti-theft lock system was engaged. When the engine is turned off without the steering wheel returning to the center position, it automatically locks; if you try to start the car at this point, the key won't turn and the engine won't ignite. This issue often occurs when the steering wheels are stuck during parking or the anti-theft device is activated. My suggestion is to gently wiggle the steering wheel left and right while turning the key to unlock it; if that doesn't work, check if the key is worn or if there's a fault with the anti-theft chip, and also inspect the ignition switch for aging. Prolonged neglect could damage components, so it's important to seek professional help promptly to avoid accidents. Actually, Volkswagen's anti-theft design is quite good, but improper operation can cause trouble, so practicing the correct starting procedure more often can reduce such issues.
