What Causes the Passat's Auto Hold Light Not to Illuminate?
1 Answers
Passat auto hold light not illuminating reasons are as follows: Brake light switch issue: If the brake light switch malfunctions, all brake lights will fail to illuminate. During repair, you can try connecting the brake light switch with a wire. If the brake lights turn on, it indicates the switch is faulty and needs replacement. Brake light bulb issue: Frequent use of brake lights can cause bulb wear. When the bulb filament breaks, it will no longer illuminate. If the car's brake lights are not working, inspect the bulb for integrity. If the bulb is found to be faulty, replace it. Fuse issue: If both the bulb and switch are confirmed to be functioning properly, check the fuse. Some vehicles do not have a separate brake light fuse and share one with other electrical devices. In this case, inspect the operation of other electrical devices in the vehicle. Identify any non-functioning devices and replace the corresponding fuse.
