Q: What does code P1349 mean?

Ignition Coil Power Output Stage 2 Open. P1349 on Volkswagen vehicles indicates that the engine control module has detected an open circuit in the power output stage for ignition coil 2, which is the final transistor inside the ECM that switches ground to the coil primary. The ECM commands the coil to fire but sees no expected current flow or voltage feedback on that channel, so it flags the circuit as open and may disable that cylinder's ignition to protect the catalytic converter.
