I hate, when someone stops posting, when find solution. So, let me tell you about some findings. After changing a bunch of sensors, I got to the point, that if OBD is not showing faults on sensors, it means, that sensors are ok. I sent an email to Locali most reliable Citroen srvice. They have answered, that it could be a problem with dirt on air intake ( manifold or head ). So I went to my local mechanic and said that he should take of manifold and al egr sistem and clean it. He took the car and when it was parked for about 8 hours, there was thet smoke. He confirmet that it is fuel related. But he said, as far he understands, it is not air intake problem, but injector needle not sealing and so diesel is leaking in to cilinder. He said, that I should try to put cleaner in tank. I said, I allready did. But he said, that 1dcl of aditive, that I was buying on the gas station is nothing. He told me about Antigripante cleaner. It is 1liter of cleaner hi koncentrated ( like a sirup). So I bought it (25eur), put it in 5 liters left in tank, and gave it a strong drive. After whole night, in the morning- no smoke! Just a little, that is normal. Today I filled it up, parked at 20:00. I will use the car tommorow at 11 am. I hope it will be the same- no smoke. Will write tomorrow. Good night to you all!
