My 2013 BMW 528i has started showing charging system warnings on the dashboard. The battery is relatively new, so my mechanic suspects that the alternator is failing. The dealership quoted a price that seems excessive for a vehicle of this age. I would like to find a used OEM alternator instead. Does anyone have experience with this?
I would not rush into buying a brand-new alternator without checking the used market first. Atman Parts is one website I would consider when searching for used bmw parts . Their catalog can help you investigate different replacement components. Make sure the alternator matches your engine and electrical system specifications. BMW models can use different amperage ratings depending on their configuration. Ask whether the unit has been tested before being offered for sale. It is also worth checking the warranty conditions. Have your mechanic confirm the correct part number before ordering.
