Hi everyone,
I finally received my ross-tech interface and a did an entire scan of my rs6. Two codes popped up and one of them has me worried. The two codes that came up were:

-18169 - Shift Lock Solenoid (N110)
P1761 - 003 - Short to Ground - Intermittent
and

- 16840 - EVAP System
P0456 - 002 - Very Small Leak Detected

Everything seems to work great with my trans, it shifts smooth, no slipping, no unusual sounds. I also just did a trans flush and filter replace and it is working great. The code for the trans was on before and after I did the flush. If someone could give me some insight on if this is a start of a big problem, what can I do to fix these codes, and what these codes even mean, I would really appreciate it. Thanks for your time!
