Volkswagen Dealer arguing with me over the color of 508 oil.........

It's also important to note (for the peanut gallery) that it's not just the turbo that's being cooled, the integrated exhaust manifold has coolant passing through it, the OEM cooling strategy is based entirely off of temps on the head. That's why these cars have several air to water heat exchangers and just a small coolant-fed oil cooler. Worrying about cooling from marginally more viscous oil is extremely silly.

As a side note, the EA888 gen 4 has divided the head and block into separate cooling systems.

Nope, not true.

More overhead for fuel dilution is one reason. OP still being under warranty with a MY2019 proves that he doesn't rack up the miles, and likely short trips. OP also lives in NJ, with cold(ish) winters, further pointing to it being a good idea to have extra protection. Will it grenade at 100K after using 508.00? No. But you are kidding yourself if you think a 508.00 is the superior choice here.

Yes, you are correct. My 2019 has 21,000 miles on it at this point.

I have a EA888 gen4 in my 2024 GTI and I can hear the coolant pump running after I pull into my garage for about five minutes. The Gen3 in my Audi A4 did the same thing
