Circuit breakers (thermal relays) (Audi A3 8L)

Thermal relays are used to protect components such as electric windows, door locks and headlight adjustments. Some of the circuit breakers are located in the fuse box.

The return of thermal relays to the initial state on some models is carried out automatically, i.e. when an overload occurs in the circuit, the thermal relay immediately opens, then, after cooling, returns to the initial state. If the circuit does not return to the operating position, it should be checked immediately.

Normal operation of the thermal relay confirms the integrity of the circuit. Some of the breakers are equipped with buttons for manual forced return to the initial state.
