Hi, i can't say i have the solution, but I have a Peugeot Expert van 2.0 hdi. I have the same error code also including p1497.

I am told it is most likely the Turbo actuator Sensor on top of the Actuator. Mine is built into the actuator and can't be replaced, however, some are 3 screws and the sensor can be replaced individually.

It could also be an ECU Signal Error or Wiring/vacuum related problem.
