8AT very specific daignostic Read Brake 2 status

Hi,

I wondered if there is a way to read out the status of transmission brakes?
The ZF8HP45 has 3 multi-disk clutches and 2 brakes. Brake 2 is activated for "Standstill decoupling" (with gear in D and foot on brake).

I used ISTA/P but couldn't find anything in EGS module.
I see NIC is active via ESYS.

So I am looking for the status of Brake2 of transmission.

Additional question: is it possible the transmission is "remapped" to never activate brake2?


reason:
My car has 100% torque while waiting on trafficlight in all modes.
should be:
ECO and COMFORT = 20%
SPORT/SPORT+ = 100%

Do you have any tune on the transmission yet? I wonder if you could use xhp to recode the TCU without paying for the maps.
