Hello.i drive golf gtd 2016 and i seem to have the same problem. the car has crossed 100 k I drive it the last 30 000 k. from the very beginning it very often turns on dpf regeneration, in the city every 20-30 km and that was strange to me. I drive the car mainly on the highway, and the oil consumption is about 1 L per 6000-7000 km, mostly the highway at speeds of 140-170km / h. Dpf is clean but shows that it has about 60% oil residue, so we came to the conclusion that it should be removed and depended on manually. did you manage to solve the problem with cleaning the dp filter and how is the oil consumption?
to mention that the previous owner changed the oil only once during the 60,000 km (probably added another 5 Lš), but I'm a little worried that he didn't destroy the engine and dirty the dpf.
