I tried finding those codes in the Crossfire service manual, but they are not there. The 2 indicates a manufacture specific code, but nothing in the service manuals. Have you tried scans as both Mercedes R170 ( 2003 SLK 320) and a Chrysler Crossfire. Curious what your scan does when the model is different.
Code P0466 doesn't show up either, but P0446 refers to problem with the canister shut off valve, or the purge valve stuck open. you tested the purge valve and it was working ok, so that would indicate the shut off valve at the canister.
