Back from the service, left the car there because there was some "loose metal" sound coming from the trunk when passing speedbumps.
They said there were 2 errors both related to a "bad explosion" in the combustion chamber. They recommended changing the petrol station and use Shell V-Power 95. Somehow having seen so many complaints from F10 5 series and now Ms I doubt it's because of petrol, but this was my story. Time will tell, if this repeats I'll update more about this issue. Hopefully it was exactly what they said it was and not a defect of "first year vehicles".
Thanks for your input and advises guys.
