VW T5 2.5 TDI BNZ 130km 2009 - White & Blue Smoke, Oil Light, Exhaust Issues: Pump Seals & More

Hi
I have a problem with the T5 2009 bnz 130 horses 271,000. Auto bought recently so I don't know much about it! a few months the unused problem is that it smokes very blue, warm engine feel in exhaust fumes, car oil lights on cold and warm from the arrow goes perfectly!
I left for repair to the mechanic and:
made engine rinse, glass shaft OK, replaced pump seals, washed out exhaust was old oil, turbo checked also supposedly OK

The first activity that the exhaust cleaning workshop did on this occasion turned out to be that the particle filter was removed and the probe hangs under the car after this procedure the car smoked much less or not at all (it is freezing cold and steam was coming out of the pipe so it was difficult to check)
They changed the oil filters, etc. so that the car could go back to "work" after stopping and recommended a preventive replacement of the Pump injection seal.
After all, Multivan is smoking as he smokes! I have to ride it and "watch what is going on!

Please give me a hint before I spend a few thousand on misdiagnosis I see that the topic is on the forums but nobody has written to the end
The mechanic bodes the cracked heads, rings, valve seals, I see that he does not know himself and it's best that I don't come back! he changed the oil and his rubbers earned me a problem!
IS THE PROBLEM a DPF filter cut out?
Where to start approach number 2?
I will be grateful for the specifics

Hello, I used to have a similar problem in Passat, it turned out that there was a crack in the head between the valves, but to recapitulate the facts, I murdered the engine myself by adding oil to a warm engine. Maybe the previous owner was as "smart" as me.

Hello, I had a similar problem and nothing nobody writes any details, only if. If the car stops 180 on the highway, nothing warms up, the temperature is ok, this is the turbo, it passes oil, it goes to the Eger cooler and is sucked together with the mixture back to the suction corrector, but a large amount at idle it goes to the DPF filter and then it smokes and as you give gas just the same
