View Full Version : 3.0T APR Stage II - Really rough downshifts in S mode
I have a 2012 A6 3.0T. It is APR Stage II. Ever since I got even the Stage I tune, my downshifts are extremely rough in Sport Mode. Like it totally jerks the car when downshifting. Anyone else experience? Any fixes?

did you get the tcu tune?
i just got epl tcu tune and have sat and driven apr tcu tunes and they both make the S mode a lot better (although i like the EPL more for smoothness). if you have stock tcu, maybe the power is too much for stock?
I don't believe there is a tcu tune available for this transmission. If I'm wrong, please let me know!

North American A6/A7s did not get the DL501 only S4/S5s and the S6/S7s. The A6/A7s got the ZF torque converter transmission.
Yeah, I have the 8 speed transmission.
Anyone else experience this or does your car downshift fine in S mode? I want to know if I have a problem or if it's par for the course...

Try one of those transmission mount inserts. I have one along with the EPL Stage 1 and didn't notice any roughness with down shifts with my A7.

+1 for tranny mount
I have the 034 Tranny Mount Insert. I got that right away when the problem first surfaced, and it didn't do anything that I can tell.
