What is the Central Locking System and What is the Fuse For?
The central locking system allows you to lock and unlock all doors of your Golf 4 simultaneously. This is controlled by a control unit connected to each door lock. The central locking fuse protects the system from damage due to overvoltage.
Imagine a short circuit in the central locking system’s electrical circuit. Without a fuse, the control unit could be damaged, leading to costly repairs. In such a case, the fuse “sacrifices” itself and interrupts the circuit before major damage can occur.
Where to Find the Central Locking Fuse in a Golf 4?
The location of the central locking fuse may vary depending on the model year and equipment of your Golf 4. However, you can usually find it in the fuse box, which is located either in the driver’s side footwell to the left below the steering wheel or in the engine compartment on the driver’s side.
