Q: What does code P1249 mean?

Fuel Consumption Signal Electrical Fault In Circuit. P1249 on Volkswagen vehicles means the engine control module (ECM) has detected an electrical fault in the circuit that carries the fuel consumption signal, which is typically a pulsed output from the instrument cluster or a dedicated fuel consumption sender. The ECM monitors the voltage or pulse pattern on this signal line and sets the code when the expected electrical behavior falls outside its programmed limits.
