There are weird issues. Stock 335 dct flash seems to work with stock gws.
Gts does not in any way.
Tcu has two routines in manual - standstill and moving. Looks like when he start driving tcu somehow stuck in standstill mode. I changed conditions for that mode, no luck.

@mspwerk, tell us please yours zb number from current dme flash.
We tried every possible solution.

335i DCT + 335i GWS
335i DCT + M3 GWS
M3 GTS + M3 GWS
M3 GTS + 335i GWS

The only combi that works is 335i DCT + 335i GWS…

These two options…

335i DCT + M3 GWS
M3 GTS + M3 GWS

Have the problem like mentioned before…
As soon as i start moving just a meter the manual shifting is blocked… Cant down or upshift the gears manually… It will last till i shut down/ turn off the batterie system.

The option with M3 DCT + 335i GWS has an other error. The GWS jumps sometimes out of the Sport/ Manual mode… Like he is not accepting this mode… The only way to get back into the Manual Mode is to shift down the gear on the steering wheel and push the GWS into Sport/ Manual Mode.

So right now the car runs with the 335i DCT + 335i GWS flash… But it is still interesting why the M3/ GTS Flash has the problem with the manual shifting…

Thanks everyone for the help! Especially Olza ❤️
