The DCT clutches are wet clutches inside a basket and depend upon the correct DCT fluid level for smooth operation. The DCT maybe leaking fluid from the mechatronics side cover, or the loom "O" ring on the top of the gearbox, or the pan gasket corner (or all of the above). Over time enough fluid will leak out that operation becomes clunky and or the DCT will overheat. Try all of the above first before going back to OEM DCT software.

correct, your DCT fluid might not be filled to its max capacity.
alternatively, use ISTA to do a clutch pack relearn.
