Check for codes in VAG-COM and the cc head. Run an output test as well.

one on the pressure switch saying it was out of limits or grounded, the other was on a flap. i rest the codes then tryed a test came back with a pressure switch code went through the reading blocks and the code was gone. so now i dont know what to do its working now but i still want to check the switch does any one know where it is located?
