miss fire

[Adayu]

Hi...need all sifu's opinion...when i start my F10(520i) in early morning,there was miss fire during idle mode And when i put gear in D position, my car engine died.
I went to BMW Quill Automobile,everything was diagnosed through computer but no fault was detected.Ignition coil also in good condition.they suggested for software update which was done but condition still the same...what should I do?
TIA

Aiyo bro....send to BMW osso kenot fix then how la?

With my limited experience,perhaps there is a vacuum leak somewhere?Some loose connection that could introduce unmetered air?

Agree with bro moots. I had something rather similar. Hose tercabut but original cause was a misfire. Had all ignition coils changed and another thing ... air regulator if I recall correctly. Fret not. When you find the source of the problem, you'll say WTF something so minor can cause such big problem.
