Purpose and operating parameters

The 110A output alternator has been designed for petrol units where stable voltage is required while simultaneously supporting multiple power consumers. It performs well in typical urban and extra-urban operating conditions, providing an adequate power reserve for lighting, comfort systems, and engine control electronics.

Selecting an alternator with the correct output is crucial for battery longevity and the reliability of the entire installation. This model is a solution consistent with the manufacturer's factory specifications, which facilitates diagnostics and future servicing.

Compatibility and part identification

The presented alternator is intended for selected BMW E81, E87, and E90 models with petrol engines. Thanks to the use of the original part number and an extensive list of interchangeable numbers, precise identification of the component in service catalogs and parts selection software is possible. This facilitates verification of compatibility with a specific equipment version and vehicle model year.

The presence of multiple reference numbers allows for the safe replacement of other alternator variants with the same electrical parameters, which is particularly important when performing repairs on vehicles with complex electronics.

Operational characteristics

The alternator has been designed to operate under typical thermal conditions of a petrol car's engine bay, taking into account variable loads resulting from the operation of air conditioning, heated windows, fans, and multimedia systems. The design provides for stable maintenance of charging voltage across a wide range of engine speeds, which translates into reliable starting and proper operation of onboard electronics.

Utilizing the original charging system architecture reduces the risk of communication interference between control units and minimizes the possibility of errors occurring in the vehicle's diagnostic systems.

Condition, installation, and service application

The item is a salvaged part intended for reinstallation in a vehicle as a replacement component. This type of alternator is suitable both for the standard replacement of a worn-out unit and for repairs resulting from charging system overload or mechanical damage. Using an original unit allows for the retention of factory mounting points and proper cable routing.

In service practice, an alternator with these parameters is often chosen as an economical solution for repairing older vehicles, where it is important to combine proper functionality with reasonable maintenance costs.
