Frequently Asked Questions
What is the difference between all the letter revisions (A, B, C, D, E)?
Will this fit the 3.0T V6 or 2.9T V6 engines?
No. This specific thermostat is engineered strictly for the 4.0L Twin-Turbo V8 engines. It will not fit the V6 powertrains found in lower-trim A6, A7, or Q8 models.
