Hi - I'm looking at purchasing a C7 RS7 from a local dealer. Previous owner had performed the APR stage 2 ECU upgrade + new exhaust. The car is insanely fast and drives incredible but the check engine light is on. I got the error codes from the service dept and they are as follows:

  • P0456: system evap leak
  • P11CD: Camshaft actuator fault


The service dept tried 3 times to fix these but to no avail. Car runs and drives just fine. Is this something you would be concerned about?
