I dropped my car off at dealership for a CEL P144C and assumed it would be covered by emissions warranty. They told me they ran the part they needed to replace, canister purge valve, in the system and it didn't come up as covered by any warranty, recall, or TSB. I said, you're telling me this emissions part that is clearly part of the emissions evaporative control system is not covered by emissions warranty??? they said they'll give me the print out of their system to prove it to me. Should this part that has been on the 2 recalls (2019,2018) not be covered under warranty? I have a 2017 RS 21k miles.
