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.
