Check this out..fly300kts had the same codes most likely gas cap. Start there 1st but could be this. http://www.audizine.com/forum/showthread.php?t=321004&highlight=P0455

loose gas cap.... tighten your cap clear the code..

[illegitimus]

the gas cap could be faulty too. if tightening it does not help, check the hoses around N80 valve for leakage or buy another cap.

hmm... cap is always twisted. even the car told me tighten the gas cap. so its gotta be something else triggering the gas cap.
