Mein Auto: 2011 550i M Sport
had something similar....

my check engine/emissions light came on.

dealer originally changed a o2 sensor, but light came back on.

car was escalated to special tech team- they found 2 leaking injectors on left cylinder bank.

SA submitted PUMA case- ended up replacing all 8 injectors and spark plugs.

all good since then.
