About this part
The alternator on your 3 Series G20 charges the battery and powers the electrics while the engine runs. A failing alternator causes dimming lights, a dying battery and eventually a vehicle that won't start.
Frequently asked questions
What should I check when ordering a replacement alternator for the BMW 3 Series?
Match the exact engine code and the model year of your 3 Series G20, as alternators differ in output (amps) and mounting. Check whether the pulley is included or needs to be transferred.
Is a remanufactured alternator a good option?
Yes – remanufactured alternators are tested to OEM specs and are often significantly cheaper than new. They're a reliable and economical choice for most vehicles.
