BMW WDS Online

Factory BMW wiring diagrams in the browser — without the Java applets and legacy plugins the original WDS required.

What BMW WDS is

WDS (Wiring Diagram System) is BMW’s factory electrical documentation: circuit diagrams from the power source through fuses and relays to the load, connectors and pinouts, component and ground locations, data buses.

How it differs from TIS

TIS answers “how do I take it apart and put it back”, WDS answers “how is it wired”. Fault-finding needs both, so here they sit side by side: for a body series that has diagrams, they open from the same tree as the repair documents.

Body series with wiring diagrams

Diagrams are not loaded for every body series at once — the list keeps growing. Series without diagrams remain available through their repair documents.
