Power loss at low speed. Then MIL.

Hello… I actually come from the Opel Forum but then it has become a used XC60 with me recently. To the car…. An XC60 model year 16 with the D4 (2.0L 181ps) the whole simple at a 6 gear manual gear without four wheel. To the fault picture: power loss under 2500u/min first noticed when the car at Friday noon at 120 in the 6th gear a slight climb high did not manage to keep the speed. But did not sooo notice strongly since i But somehow already in the back of his mind that he feels lower rum than the day before. Today it can then be like it had to come… The MIL/MKL went on of course during the weekend excursions Saturday after 1 pm so nothing with “just read out mistakes” Does the car have a typical flaw where you say “the food”? After Norlauf it doesn’t feel like I would type on it that the first turbo doesn’t work properly T. Thank you for the answers.
