This issue now has at least 3-4 owners with same issue.
I pointed this out to the Factory Rep but did not help much.
Every time I go in i will askd for update list and see if Idle surge is on the list.
i have also sent mail to local dealer with issue and the fact that this is a SAFETY issue.
Very, very sad that BMW is ignoring customers and safety issues.
I am a 1st time BMW owner, may very well be my last.

On another note...muffler on order will let all know if that stops the ratttle. Again, took 4 trips to get that done!!!!!
