The product is in used condition, which allows for an economical replacement of a damaged alternator while maintaining the original BMW specification. A used generator is a sensible solution for drivers who want to maintain the consistency of the electrical system without resorting to cheaper replacements with uncertain parameters.

The main benefits of using this alternator include:

• maintaining factory charging characteristics in BMW vehicles with a petrol engine,
• perfect fit for serial mountings and electrical harnesses,
• suitability for vehicles equipped with extensive onboard electronics.

Before installation, it is recommended to perform a standard verification of the charging system (condition of the belt, pulleys, ground connections) to fully utilize the potential of the installed generator.
