Typical applications include powering high-current consumers, controlling auxiliary modules, or protecting critical circuits from overload. Thanks to its compact design and compatibility with factory sockets, installation is quick and does not require any wiring modifications.

Benefits of using an original relay

Using a relay from the VAG group ensures consistency of electrical parameters with the vehicle manufacturer's factory specifications. Properly selected current and voltage characteristics promote stable system operation, reduce the risk of contact overheating, and minimize voltage drops in the circuit. For workshops and users, this means predictable system behavior and easier diagnostics in the event of any faults.

Condition of the component and installation aspects

The offered relay is in used condition, making it an attractive cost-effective solution while maintaining proper operating parameters. A component of this type, when used correctly, is characterized by a long mechanical and electrical service life, which is why its reuse in a functional circuit is a practical service choice. Its compact design and standard four-pin configuration facilitate replacement in an existing socket without the need for installation modifications.

Identification and vehicle compatibility

The relay belongs to the Volkswagen brand range, which facilitates its identification in the context of VAG group vehicles, such as Volkswagen, Audi, Seat, or Skoda. The product has an assigned OEM part number and corresponding interchangeable numbers, which allow for verifying compatibility with a specific model and equipment version. Additionally, it is marked in the store system with a unique SKU, which speeds up the ordering and service process.
