Did they remove the passenger's side wheel and wheel well liner when they did the smoke test? If they didn't, they never looked at the EVAP system.

Yes they removed the wheel and liner.

Update: I threw in the towel and took it to the dealer. They performed a smoke test and determined these parts to be faulty/leaking so they replaced the following parts:
1. 996-201-221-07 ACTVD CARBN CO
2. 996-605-201-01 SHUT-OFF VALVE
3. 996-605-213-01 CARBON CONT VA
Codes were reset. After driving the car around for a few day (65 miles) the CEL came back on. P0455 and also a P0430. I'm almost certain these two are related.

I am bringing the car back to the dealer and need to be prepared with what they may claim.

Any advice ? Can an Evap leak cause the P0430? I'm also holding them responsible for the P0455 code.
