Purpose and compatibility

The presented alternator has been designed for popular VAG group models, such as the Audi A1 8X, Audi A3 8V, Audi Q3 8U, and Volkswagen Golf Mk7 with petrol engines. The design, adapted to the requirements of petrol-powered units, allows for seamless integration with the factory electrical system and onboard electronics.

The alternator's operating parameters are selected to provide sufficient current reserve for modern comfort systems, lighting, safety systems, and multimedia, which is particularly important in highly equipped versions of these models.

Technical and functional characteristics

The alternator operates in a 14-volt system and offers a current output of 140 A, which provides a solid foundation for a stable power supply to all consumers in the vehicle. This configuration is typical for modern compact cars and crossovers, ensuring a balance between performance and mechanical engine load.

The device belongs to the Alternators and generators group, meaning it is responsible for both charging the battery and providing current power to electrical systems while the engine is running. The properly selected drive ratio and the design of the rotor and stator allow for efficient operation across a wide RPM range, from city driving to highway speeds.

Condition, origin, and benefits of use

The offered alternator is a used part, sourced from dismantling, which allows for combining factory fitment with a cost-effective purchase price. Choosing an original component from the secondary market is a solution often preferred by users who want to maintain compliance with the vehicle's factory specifications while avoiding the risks associated with low-quality replacements.

Key benefits of using this alternator include:

• factory fitment for mounts and electrical wiring in the listed models,
• operating parameters adapted to the load typical for modern comfort and safety systems,
• the possibility of an economical repair of the charging system while maintaining the original design.

Installation and maintenance tips

Before installation, it is recommended to verify the alternator's compatibility with the specific engine version of the vehicle and to check the condition of the drive belt and accessories. A correctly selected and installed alternator reduces the risk of voltage drops, starting problems, and interference in the operation of onboard electronics. For vehicles with extensive electrical systems, maintaining adequate current output is particularly important, which this model ensures.
