Buy why the blue smoke on first startup in the morning? This i a petrol model.
I suspect you might have symptoms of turbo starting to leak. They will have to remove the plumbing from the turbo and check for sings of oil. I know my dealer has had a few 320i F30 with turbo starting to fail (smoke on start up). It is also not a quick process because BMW SA wants foto's to be sent of the plumbing if they do find oil in your intake system and they will also check your computer for any illeagal chipping and so on. I Suggest you take it to the dealer and have them check it out.
I know they designed the F30 with start stop function but in my opinion its not good thing for the turbo if you have a heavy foot. Hence the reason I had mine reprogrammed by BMW to stay off when I switch it off. I only use the Start stop function in heavy traffic.
Keep us posted on what their findings are. I recon your car will be with them 3days for them to check it out and if they have to replace turbo
