Describe rough? I know when cold my previous Cooper D used to idle at about 1200rpm to warm up, then after a short period maybe pushing two minutes it would settle down.Hi
My 2014 f56 petrol/manual has started to exhibit rough & erratic idle on start up from cold. After about 30 seconds it settles and the engine behaves normal.
Has anyone experienced this.
hag6, just curious if your HP pump cover replacement had any effect. I was at the dealer today to get a new battery installed and the service advisor (who to me looked to be about 15 years old) said that the rough idle should not be there, which brings into question the validity of the article I posted earlier.Thanks for all your replies. The erratic idle happens roughly 6 out of 10 times. Like Keni it sometimes cuts out when reversing. Got my dealer to check it when I took the car for its 1st service but the diagnostic failed to reveal any fault. Had the high pressure pump cover replaced as per enhancement - I wonder if this is cause of the problem. I will let you know if the issue has improved,
