A week or so ago me check engine light came on. Code was P0420, an issue with the catalytic converter. I brought it to the local Subaru expert in town. They advised that the catalytic converter was bad and needed to be replaced (though at this point I don't know what they did to diagnose). Took it to the dealer to presumably have the catalytic converter replaced under warranty.
When I picked up the car, they had not replaced the converter. They reset the code, road tested, and the light did not come back on. They advised that this is how Subaru tells them to handle the problem. They did say that if the light came back on, they would replace the catalytic converter.
Sooooo... my question is whether or not this is reasonable and/or standard procedure. If it is, I won't worry too much about it for now !
Thanks, Dan
