Въпросът е с кой точно да го сменя. Според тоя service bulletin
https://static.nhtsa.gov/odi/tsbs/2022/MC-10208466-0001.pdf:
"Coolants G11, G12, G12+ and G12++ and G13 have been replaced by a newly introduced G12Evo coolant.
...
G12Evo coolant has been introduced as the factory fill coolant in current production.
...
G12Evo coolant is backwards compatible with all engine concepts, EXCEPT for the GEN III EA288 TDI (MY2015 2.0 TDI CVCA and CRUA)."

https://static.nhtsa.gov/odi/tsbs/2020/MC-10176873-0001.pdf обаче пише:
"The model year 2018 and older vehicles use - G13 part number: Ready to use G -A13-774-1G-DSP."
Значи на новите модели слагат G12Evo фабрично, и е съвместим и със старите модели, но от друга страна пише, че модели преди 2018 г. ползват G13 и сега чуденката е между G12Evo и G13. Иначе тоя, който е сипан в момента, мисля, че не е съвместим, защото оранжев намирам само G12 и G12+ и определено май има нужда от спешна смяна.

https://www.audizine.com/forum/showthread.php/951949-Coolant-Type-G13-or-G12Evo май бих сложил все пак G13, ако все още може да се намери, заради фосфатите в G12Evo:
"Per the chart in the TSB link by Manny, you can pretty much put G12++, G13, or G12evo in whatever. Except the latest vehicles that require G12evo; use only G12evo in those.
G12++ = glycol + Si HOAT
G13 = gycerin + Si HOAT (glycerin supposedly more env friendly to produce)
G12evo = glycol + PSi HOAT
Personally, I'd just go G12++ if it's still out there. Avoid the phosphates content which the C6 was not designed around. Apparently phosphate HOAT was common in the Japanese vehicles. Silicate HOAT was common in the German vehicles. But seems the new metallurgy needs a mix of both."
