Q: What does code P1626 mean?

Data Bus Drive Missing Command From M/T. P1626 on Volkswagen vehicles indicates that the engine control module (ECM) expected a command message from the manual transmission (M/T) control module over the data bus but did not receive it. The ECM monitors the controller area network (CAN) for a specific message from the transmission controller and sets this code when that message is missing, often due to a communication fault or a problem within the transmission control module itself.
