Volkswagen’s electronic fuel-injection and engine-management system used in North American Vanagons from 1986 onward according to Gerry’s terminology FAQ. The archived FAQ distinguishes it from Digijet, which it associates with 1983.5–1985 Vanagons; Gerry’s technical bulletin index also lists Digifant topics for 1986–1991 models. Verify year, engine, and market before using system-specific parts or procedures.

Digifant ECU
Engine and fuel systemsEnglish · machine-assisted draft
The electronic control unit (ECU) is part of Volkswagen’s Digifant fuel-injection and engine-management system. Gerry’s 1986–1991 technical bulletin index distinguishes these applications from the earlier Digijet years. In a January 1999 list thread, an owner of a 1986 Westfalia reported that the engine quit after cooling-system bleeding and asked whether fuel starvation or a failed Digifant component was involved; the thread records a troubleshooting question, not a confirmed diagnosis. Check engine code and market before identifying an ECU.
