P1239 · VolkswagenCylinder 3 Injector Circuit Open Circuit

P1239 on Volkswagen vehicles means the engine control module has detected an open circuit in the electrical path for cylinder 3's fuel injector, so no current can flow through the injector coil when the module commands it to fire. The module monitors the injector driver circuit and flags this code when the expected electrical load is missing, which prevents cylinder 3 from receiving fuel.
