2001 325 CiC - Engine warm, idle drops low then recovers

G'evening all,

I've a few items to tend to on my wifes '01 325CiC 5 speed. One of which is the brakes (see separate post) and another is a slightly irritating idle issue.

I'll try to describe the symptoms. With the engine at operating temp, coming to a stop the idle drops well below its normal idle speed - to the point that it almost stalls, but then recovers immedately. The majority of the time it drops and recovers to normal idle right away but occasionally it will "cycle" 2 or 3 times before settling at it's normal idle. The computer is not lighting the SES light.

I've read a number of posts with symptoms that sound similar but those have concerned fluctuating idles with a cold engine.

Any insights??

Thanks much,

Dan

First thing to do is contact dealer and check out, if your car has latest DME software updates.
Other thing to do would be, to ask them (if not update is avilable) to set engine idle rev speed from 750 rpm to 875 rpm-problem will be solved !
Best regards.
Z.

DME software updates?

Interesting. Are there periodic updates issued to address known problems?

Thanks Z.

Let us know what you find SS. My idle problem was related to a vacuum leak in the air duct.

Can you tell me more about your issue, Hootie, because when I've had the hood open with the engine running can hear what I think sounds like a vacuum leak - just can't seem to locate it.

Thanks much,

Dan

Follow the link to this thread. It was beat to death here. Good luck. If that's your problem, easy fix.

Dan-

Once and awhile my car does the same thing, and I've pinpointed to the A/C compressor. It will only do it if the air is on, and when the compressor kicks on and off. There is an electronic idle control valve (not sure what BMW's technical name for it is), that I believe is just sticky. It didn't do it when I replaced everything under the hood, now it does.

If you normally run the A/C, try turning it off and see if it still does it. If you're not running the A/C, I don't know what else to go for, other than what others have already posted.
