Older BMW electronics can be their own repair project. This short clip focuses on replacing capacitors in the general module from an E31-era 850i or 840i. It's a look at the module work rather than a complete diagnosis of every electrical problem an 8 Series might have.

A general-module capacitor job is circuit-board repair, not a normal bolt-on car part replacement. This eighteen-second clip is a quick look at that work. Match the module version and component ratings before attempting electronics repairs.
This DirtyKurty short covers BMW E31 general module capacitor replacement for the BMW 850i and 840i 8 Series. The general module belongs to the car's body and convenience electronics. As components age, module troubleshooting may lead owners to investigate electrolytic capacitors and circuit-board repairs. This clip is brief and should not be treated as a complete soldering guide, electrical schematic or verified cure for every E31 electrical symptom. Search topics include E31 GM module, 850i and 840i electronics, capacitor replacement, BMW general module repair and vintage BMW electronics.
