what is your question?
Customer: replied 1 year ago.
On cold start ups the car (135i) will sutter when revved and driven until it has warmed up and then shut off and restarted, after it has been started again the sutter is gone and drives normally. I'm suspecting injectors. And also when the car is in neutral and the clutch is none pressed in I hear a noticeable chatter/clunky goes away if the clutch is depressed. Read on forums it is the Dual Mass Flywheel and is deemed normal by BMW. Is this true? And how loud can the chatter be to be consider not normal?
