Maybe an o2 sensor is going bad or it could be that they did not put everything in all way. Did the code go away for increased emission. If so have them check their work.

How many mi or km have you driven the car since you got it fixed. If the code is not coming back up after driving for a while then it was obviously fixed. I would take it back and have them check their work. They did not plug something all the way in or it could be the actual parts they used. What plugs and coils did they use. These cars cant take any manufacture products without having issues. If you took it to some where like pepboys then that is your problem. You could of done the job with the right parts and still saved $$$. It would of took you no more than 2 hrs since you have a 545i

Do you have the means to see what code are stored in the engine module. Im sure it will tell you something. Who did the work? If it wasnt an indy or BMW you should have your answer once you pull it up

Like does it only happen briefly for a split second or longer?
Does it happen every time or some of the time?
Only when cold start or cold and warm engine start?
