Adaptions are unlikely to help - that's to (re)learn clutch clamping pressures etc. The issues described sound like mechatronic problems.
I'd be taking it to a VW dealer. Depending on the service history of the car (how comprehensive it is, where all the work was performed), it may be possible to request at least a partial goodwill claim with VWA. But you won't know until you speak to a dealer about it.
Failing that, a VW specialist independent (ref Recommended Repairers and Parts Suppliers) should be able to source you a mechatronic and fit it.
