In a Syncro drivetrain, a driveshaft decoupler disconnects the prop shaft so the front axle is no longer driven through it; it is not the front differential lock. A Gerry discussion on 16 May 2004 compares the original non-viscous-coupling layout, which used a driveshaft decoupler, with viscous-coupling Syncros while debating front-lock behavior. The thread is historical community discussion, not a retrofit procedure; identify the drivetrain configuration before interpreting parts or controls.

Dehler was a German conversion company whose VW Transporter campers and business-van layouts appear in Gerry’s preserved terminology FAQ. Archive discussions make the model distinction clearer: a 1999 thread concerns a Dehler Profi conversion sighting, while a 2005 thread describes a rare Dehler Profi high-roof camper. “Dehler” therefore identifies the converter; Profi is a particular conversion line, not a separate Transporter generation. Confirm the exact build and year for parts or fitment.

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.

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.
