How does the 2.7t work?
 

Is there a link showing how the turbos work in the bi-turboed 2.7? I'm interested in learning how that works.

nice reference

Great link to good info. Do you have a link to the Audi source for these Self Study Programs, and specifically to those referenced in this treatise on Variable Valve Timing, # 182 and 192, and the index for this stuff? Thanks!

Great document!!

I didn't realize there were differences between S4 and A6 engines. Is there an article which
 

focuses on these?

There isn't a difference. Guide was probably printed prior to final model specs
 

Both the s4 and a6 have the same power and torque curves according to their model specs. The guide shows a difference in output between these two vehicles and that is not correct.
