Passat reluctant to change gears

So I have a VW Passat 2012 dsg. I got the mechatronics rebuilt after a solenoid was causing issues. Now the car has no codes but is reluctant to switch from first to second and second to third. All other gear changes perfectly. And if I drive a bit more aggressively all gears changes perfectly. What can I do?

I tried doing the calibration sequence on Ross tech but cant get the clutch adaptation running with the error message of functions not available.
