When i first installed my ESS TX and TS, i got a check engine light which then dissappeared after another 100 miles. ECU adaptation? Did you get the correct AA software update?

It is not normal to get any CEL when the kit is first started up. This only happens if you have turned on the ignition with some sensors not connected registering a fault on the missing sensors. The CEL will go out again once the DME has received proper signals for a while.

Cleaning Idle Control Valve with zero cost

I just finishing cleaning the idle Control valve myself with zero cost, and will return the new valve bought .
A few days ago the checking engine light was on in my 2000 bmw 323i, read the code P1510 (Idle Control Valve Stuck), check out the various listings in E46 Fanatics, decided to fix it myself.
First taking out the idle control valve, realize the control part inside could not be moved by crewdriver, well, I though it was really stuck, ordered a new one on line. But meanwhile sprayed some WD-40 in it. Next day while waiting for the new part to arrival, looked at the old one, suddenly realized it's control part moves when it is turned quickly in hand...I cleaned it up, put it back in and cleared the error code.
Error code never comes back again, test drived, wohl, it's fixed!!! (saved a couple hundred dollars for the dealer...)
If someone needs the steps to take out the idle control valve, I'll be happy to post.

Steps to take out Idle Control Valve

First letís look how the Idle Control Valve looks like (last picture attached):

And where it locates under the hood:
http://www.realoem.com/bmw/showparts...95&hg=11&fg=40

Here are the steps to take it out:
1. Remove complete air filter housing (1st picture attached)

2. Remove housing for micro filter for interior ventilation (2nd picture attached)

3. Remove adjust unit (refer to the hyper link above).

4. Remove plastic wall between engine and brake cylinder (3rd picture attached)

5. Disconnect Idle Control Valve connector

6. Loose Idle Control Valve intake pipe

7. Pull idle Control Valve out with Bracket Idle Adjuster together

Installation is just the reverse of the steps above, be careful not let anything get into the engine. Good luck!

I also have a 2000 323i and I was planning on chenging this soon, because I've been having cold weather start up issues, so are those the instructions for a 323, I thought I had to remove the intake mani???

No, you don't need to remove intake manifold.
Actually the 3rd step "Remove adjust unit" is just to make a little bit more room for the following steps.

Had the same problem occur to me. Ended up replacing MAF sensor and Idle control valve... works perfectly since. It was a bit more work that I wanted to tackle since I dont have a garage and park on the street, I had the $tealership do it, and ran about $1200 bux for both.

^^^Wow...$1200? guess they don't call it the stealer for nothing. I bought a new MAF and ICV, and (following the instuctions above) installed both myself in about an hour last night. $300 total

Damn, so glad I found this thread. I've been having horrible issues with my cars idle. Every time I let off the gas and let the rpms dip down to what seems to be idle, they fall lower, sometimes stalling out the car as I come to a stop. I suspected it might be my ICV and have been searching the forums for a diy so i can check it out and possibly clean it. Looks like my search is over

I had big plumes of white smoke bellowing out the back, car would not idle or even stay on. They tacked on hrs for diagnostics, flatbed towing, and I supposed additional hourly charges for working with the supercharger setup. Frankly I was surprised the dealership accepted the job, since they had refused to work on it in the past. The only other independent shop in town was VAC Motorsports in south philly, but without elaborating, they have let me down as far as service goes. Given the time and space, I could have done the job way cheaper, but those were both luxuries I didnt have at the time.

The service I recieved from BMW of the Mainline however was exceptional.

I first cleaned it with "no residue cleaner" like those for electronic connectors, then sprayed some WD40 for lubrication.
