Hi everyone!

I know this was a long time ago, but i am having the same issue with my car at a main dealership.
They're getting the message 'PCM unique identifier is not recognised' when trying to connect to the car with the Ford IDS unit.
They managed to connect a snap on handheld tool to it which tells them it's a boost leak but doesn't allow any further diagnostics or datalogging (as is given through the Ford IDS unit).

My questions are:
What made the decision to check the EVAP system when the fault code P22297 shows O2 sensor bank 1 faulty?
Were you getting any PCM issue messages?

Cheers

Simon
