I talked to a service advisor at the Yota dealer up the road from where I work, and he was very agreeable, and said that a tech would have to verify the smell. If he verified it, they would replace the cats according to the tsb and it would be covered under the emissions wasrranty. I think it helped that I was wearing my work uniform from my BMW dealer and told him I was a technician there. Maybe. It will be going in this Saturday to get looked at and hopefully everything goes okay. I'll post the results.
