Looking for some help. 2010 116i M sport with the 2.0na engine. When cold, car ticks over perfectly. After about 15 mins of driving when idling you can feel it getting a little bit rough. Nothing too bad, but the longer you idle the worse it gets. No EML. When running car runs perfectly not a flicker. Today left it idling for 10mins after I felt it and then revs started to fluctuate but still no eml. OBD scanner can’t pick anything up. Turned it off and back on and was still rough but only a little bit like when it just starts. Anyone had anything similar or can point me in a direction of where I should start looking?

When was the car last serviced ? The symptoms you describe could be due to an air or vacuum leak, old hoses seals and vacuum lines can start to crack when cold they are stiff and don't leak (as much) when hot and flexible you see the issue developing.

Your OBD Scanner needs to be BMW capable a standard scanner will only see critical functions.
