Nvm, I gave up.....I just cleaned 1 side which is the side I could see...1 side of the 'T' shape....
Same with the TB opening...don't know how to get the last intake elbow out....so I just sprayed the cleaner from the last intake elbow and stuff a cloth in to clean.
The rubber intake tubing is all held together, including the connection at the throttle body, with hose clamps. Feel around the circumference of the clamp for the hex head. The hex heads at the throttle body and the ICV on my car were located at very awkward angles, but I was able to loosen them with the help of a flex driver.
When you put everything back together, you can reposition the clamp so that it will be more accessible the next time you have to take something apart.

Can you tell me what the piece is call in picture under step 12 where you have the red arrow pointing to. My e46 that piece is crack which lets a lot of air in. That i think is the cause of why my idle is acting crasy and shuts down my car sometime.
does this thread only pertain to coupe 5 speed?
my god, clean your engine bay
That can definitely cause that and it's a very common problem. I would go ahead and replace both the upper and lower intake boots(the one you're referring to is the lower) if your car is over 4 yrs old. They're $15 or so a piece.
Anyways, I thought I'd say I just got done cleaning the DISA valve and the ICV. Took me 1:10 start to finish.
Thanks for this great write up! My ICV was stuck when I pulled it out, I sprayed it down with electronic cleaner and then it started moving on the inside when I shook it, I hooked everything back up and my rough idle was gone!!! My only question is if it's safe to drive around without installing those annoying little metal clips on the ICV ?!!?! I couldn't put it back in and then I lost it ... it was also a pain to put back the lining (the one the OP referred to as an "obtuse piece of plastic") any suggestions on how to get it back on easily?!?! Thanks again!!!!!
Thank you man, I did replaced ICV and so far no stalling and no rough idle, I do own Bentley manual and according to them I would have to remove da whole intake manifold, which is not easy task to do..great post.
I think I need a new DISA. I unplugged the power to it and all the noise went away. The video can be found here:

Two questions:
1) Is there any way to repair this part? Otherwise, it's going to be $200 for a new one.
2) Using this DIY as a guide, can I just remove the DISA without removing other items? Is it just the two torx bolts or will something have to go to free up access?
Great job putting this up. I live in L.A. and its not cold but my car stalls a lot espacailly when I'm in stop in go traffic with the AC on. It dips way to low. You think if I clean my Idle Control valve it should fix this problem?
Thanks bro! I have a great weekend lined up now. Stop oil leak do to striped threading on the oil pan, replace water expansion tank, clean the ICV. : )
1)You may be able to epoxy the shaft to the paddle to take up the play, but personally I just called Vines BMW and asked for a manifold adjuster unit...$75
2)Yup, 2 torx bolts and you don't have to touch anything else to remove it
Now, can someone help me out? The little F connector off the intake elbow in the original DIY pics of this thread....can anyone tell me where the line to the small nipple (the one that broke) goes to? My vacuum lines are all mixed up and I can't get any info on it. Please help!
Yup, just got mine in....they'll quote you around a hundred for it, tell them you need it for $75, that's what I got mine for. Now can someone answer my question?? lol

Is that them? Did they send you a new part? refurbished? used?
Sorry, I don't understand your question. Rephrase?
Yea, that's them....That's for a used one, I just told them to try and check it for play and they sent me a good one, no more chatter.
On the intake elbow there is a little plastic F shaped connector with a big hose and a small hose, where does the small hose go to?

i just finished cleaning my ICV. that thing was so dirty. i only have 100k miles too. i was cleaning it and big chunks of carbon was falling out. after i cleaned it the valve moved freely. my problem is better, the car doesn't stall but still has some weird idle issues. next thing i'mna do is clean the maf.
also i suggest removing all the pieces. at first i didn't want to because it was too much work, but after loosing two sockets(i only found 1) i found the extra space useful.
great diy.
that would've been the smart move...hehe
