Oil consumption CRDI ProCeed

Good morning, on my procedure there seems to have been increased oil consumption since the day before yesterday. I bought the car as a 2 year car and now drove 1000km. Everything is good. Now I drove on Thursday 250km. After 70km the warning light went low at oil level. But then I drove still finished and bought matching oil in parallel. Can happen. I then filled a total of 500ml and took a photo after 2h standstill. It was before filling exactly at the minimum and later maybe 2mm about it. Now I drove this morning and after 30km the lamp went on again. I find that strange. I go immediately when he has confessed a little look. But if the lamp concerns it will probably again be too little. My question is whether certain problems are known with the CRDI? In the workshop I have to go one way or another.
