Hello, i have an E91, 267,000KM, and every 1000km i pour 1 litre of oil. The car doesn’t smoke. Could be turbo or something else?

Has the breather been changed/ updated?

it could be that the turbo is letting a little bit by. Is there any evidence of oil leaks, also all engines will consume a tiny amount of oil and you say it's done nearly 270000 km so it will burn a little more than when new it could be the piston rings are getting worn. you won't see any smoke because the dpf will filter out a lot of that. probably best to get it looked over properly because there's countless places oil could be getting lost
