2013 S6 stall at stop/reverse

[Joe645733]

Hi all.
Car has 110k miles along with an EPL stage 2 tune and EPL TCU time.
- Today the car has been stalling and dying if I put it into reverse if I don’t give it gas.
- Car also almost stalls when coming to a complete stop or going from 2nd gear to 1st. Again, it will stay alive if I give it gas right when I stop.

Any suggestions? Thank you

Scan it, maybe turbos

I'd start my diagnosis with fuel. If you have the means, probe the fuel trim and pressure as you drive and watch the graph as it's showing the symptoms.
If these problems started happening just after the tune, then that probably means they didnt tune it quite right for low load/ low throttle angle.

Okay so no codes on ecu or tcu.
I recently changed the trans fluid with filters and problem still happens.
No problems occur the first 20mins after driving.
Turbos aren’t making any noise and the car still
Pulls hard and smooth @16lbs of boost.
I just purchased DS1 and b.e TCU tune. People say get away from EPL so I might as well

I don’t wanna be the bear of bad news... it’s a clutch issue. Only time an auto car will stall, typically dsg will do it, when the clutch is on its last leg. I’ve replaced a few DSG clutch packs. First symptoms of clutch failing, rough accel from a stop. And rough stop like trans isn’t happy. There’s not gonna be a trans code until the car doesn’t move anymore unfortunately. Or unless it picks up clutch slippage.
