Saying hello + Exhaust question

[Ares4]

Thanks, I found the port. I have two codes: P1217 and P121B which both sound like active exhaust codes. Yes, the light came on when it was pretty cold... I think it was 5-10 degrees. We'll see what they say at the dealer next week.

Hey @SeaDog was the dealer able to do anything for you on this?
So far I have reset the codes 3 times over the last couple weeks. Everything is working but as soon as the temperature drops the check engine light comes back. It doesn't seem to be related to dirt or debris just an issue with the sensor in cold weather.
