Strange problem with my Passat B7 1.6 TDI 77KW

[zaxspeed]

First of all,i whant to say hello to everyone, new here. English is not my 1st language so , i am sorry for bad English. I have Passat from title and montn ago it starts to doing regeneration almost every 20 km. Car is 2013, 340.000 km .DPF is cleaned too 0% on 220.000, i did injectors and it works just fine, change DPF pressure sensor but it change nothing. 3 times car was on diagnostic and shows NO ERRORS at all. It looks like that it is doing false regeneration and in last 3 weeks it rise crankcase oil level, so i urgently changed it.
Does anyone have any idea what this might be about? Every suggestion is welcome. Thanks!

How was DPF cleaned? I believe you have to do some adaptations with VCDS, OBDeleven or similar powerful scanner to reset the DPF

Also, you need to figure out where is coolant leaking into oil, there is a few possibilities: EGR cooler, oil cooler, head gasket

It is diesel goes into oil, not coolant

I'm going to defer to other people here, as I have never experienced fuel in oil.
From logic it seems you have a huge issue with injectors, otherwise I don't believe a lot of fuel can get in the oil, so much to fill the crankcase.

I did injectors and they are fine now, but the problem is that passat doing false regeneration because sometimes it goes white smoke and sometimes goes light blue, whe its stands in place (traffic light)

How was the DPF cleaned, and did you reset the ECU to new values?

My understanding is that even when you change to a new DPF, you have to go in a module and change a value to reset the accumulated ash content.

I willl check with man who cleaned that

 

[zaxspeed]

I cleaned DPF to 0, cleaned and check lamda , new termostat, cleaned and check intake manifold , restart dpf service and it still regeneratte every 30 km.ENIGMA!!!
