I recently got a CEL and only 1 code is shown P2755
After some searching i found a TSB

chrome-extension://efaidnbmnnnibpcajpcglclefindmkaj/https://static.nhtsa.gov/odi/tsbs/2013/SB-10053889-6593.pdf

But it does not list S6/S7 vehicles.
My car is 2013 S6 with 60k miles.
I need help getting part number for the valve and location so i can replace it.
I will need to check condition of the contacts due to possible coolant migration.

Appreciate your help.
