A cheap ELM327 paired to your phone will show live MAF data so you don't need Vida for that either.

Another possibility is the stepper motor for the flaps. After coming back from the main dealers diagnosis I saw the arm was off and had been for some time. Not sure the motor is ok as when I rev gently the arm moves but doesn't hold position but goes back to its start position regardless of the revs.
