They pull TU, though I'm unsure which version they use.
I almost bought a new GTI recently and top tier was 1.9%. The sales rep guessed that I would probably get 2.9% or 3.9% with a high 600s TU.
I had two CU preapprovals in the 3.xx% range with EQ pulls.
My owned free & clear 2007 GTI is getting some love this week instead
