2011 S4 with 67K miles, mech replaced 5 months ago (10K miles) due to hiccups during shifting. Was shifting good until the last couple months. Transmission shop says it's normal. Shift pressures are normal and equal (per mechanic).
Here's my issues that I had before mech replacement and now coming back:
-developing longer engagement when at a stop and going from brake to gas. Yes I know the DSG acts that way. But right after mech, there was hardly any delay. I actually noticed I had to keep my foot harder on the break to keep it at a dead stop. Now it's about a 3 second delay before you can feel it engage.
-when coming to rolling stop (in second gear) and give it gas, it acts like when you let the clutch out too quick, like a little hop before it goes. Or it will act like your letting the clutch out too slow and then when it shifts into 3rd, it acts perfect.
-issues seem to be most noticeable in 2nd gear, once in a while in 4th. If I really take my time and ease into the gas from any rolling stop, it acts much better. But as I mentioned, it seems to be progressively getting worse. I have to baby the thing when leaving stop lights and stop signs if I don't come to a complete stop.
It's odd that it was awesome at first, now not so awesome.
I do have APR ECU stage 1 tune that I put back on right after mech replacement. Before replacement, I had shop remove APR ECU and TCU tune to make sure that wasn't the problem. I am still waiting for APR to build a TCU tune for my new software.
I'm starting to wonder if it's clutches now. I did have old fluid tested and no sign of clutch material and mechanic said fluid looked really good for 38K miles.

Could be one of the seals is bad or solenoids but you should see this in log. Did you ever log your TCU ?
