I really dont think that the map will be at fault, its exactly the same as everyone else's.
I would take it to a garage and get a proper diagnosis before exploring DSG servicing.
There is also a reset that can be done with the DSG box which can be done with VCDS i believe, but again the symptoms of a DSG gear box with faults are never clutch slip.
Keep us informed of what happens this is quite interesting, Obviously not for you but you know what i mean.
