Wass up Jake??? Hey man, thanks for the video.... I may need to do this after I install my MAF and wait to see if it stalls on me again. Will keep you posted.

Kudos to Jake for his video posted to Youtube on removing and replacing the ICV (Idle Control Valve).

Mind you, like most of us here I am not a mechanic by any stretch, but Jake's video gave me the confidence to attempt a repair that the dealer wanted $756.00 to do.

With the assistance of my wife (she has small hands for tight spaces and held flashlights and tools for me) I started at 11:30 and ended at 4:30 PM. Everything went pretty much according to the video except the following:

1) The 2 hose clamps on the lower intake boot (the upper small accordion hose clamp and lower boot clamp) were on the reverse side of the boot, hose, etc. I just could not get to them; no space to maneuver. They must have been installed at the factory while car was raised in the air. After 3 trips to the auto parts store and buying numerous tools over 3 hours, I actually found a carburetor tool (a long flexible spring with a screw driver handle and socket on the end that worked perfectly on all my hoses and clamps) that saved the day. If not for this problem I would have finished the job in 1/2 the time.

2) The idle control valve did not come out as I expected. The 2 t-40 bolts and 1 10mm nut removed I felt as though I might break something...but frustrated I sent Jake an email asking for help. He called me within 2 minutes and gave me the confidence to just keep wiggling and pulling and out she came.

The amazing thing is that the reassembly after cleaning the ICV only took about 1/2 hour. I drove the car to the auto parts store and returned over 50.00 worth of tools I did not need.

Thanks Jake for a solid video and the telephone support you gave me on this one.

If anyone is wondering if you can do this....just take a break every once in a while, stay hydrated, and don't be impatient with hoses clamps, etc. Now I will drive the car this week and see if it stalls again or if any trouble lights come on.

By the way, last week I replaced the MAF and air filter without a hitch.

I'm thinking about doing this maybe tomorrow. I was also going to do the oil filter housing gasket. Is this in the same general area? Might as well do both since im going to be working on the ICV? And what tools would be recommended for both jobs? I kno the T40, 10mm socket, and flathead are the main ones for the ICV job. What about the gasket?

Thanks for the kind words and it was good to help out another member. Glad that you were able to do this job because like I said, most of the jobs require those parts to be taken out.


By the way, I take credit, debit, paypal and cold hard cash I kid I kid.

By now you probably have it out....listen.... you have to keep pulling on it...up and down...side to side....it will come out...you will not hurt it by pulling hard and rocking side to side...I have done it twice and it will come out...keep pulling and wiggling while you pull....let us know when you get it...

I know this is old, but my car has had the rough idle at start up throwing the Lean Codes with Fuel Cutoff. I turn the car off and start back up and everything is smooth. Lately however, it has gotten worse. The last 2 days at cold startup, the car would idle even rougher and die. Still throwing the same codes. I have just figured that it is time to change the coils, but the codes usually say different cylinders misfiring each time. Sooooo, could my ICV be causing this??? I smell fuel when this happens....the last 2 days anyway when it has been really bad. Could the ICV just be dirty and taking longer to loosen up on cold start?

You smell fuel because of the misfires. The car is loading up with fuel because it isn't being ignited. That is why you have misfire with fuel cut off codes.

Typically a bad ICV will cause poor idle but not misfires since it only controls air flow at low RPM and is bypassed at higher RPM. I would tend to lean towards coils too. My brother in law just had this issue. Had misfire codes jumping all cylinders but we replaced 1, 3 and 5 (most common ones going bad) and all is well. I can get you used coils for $20 each. I think I have one good one you can have.

Changed my plugs last night before I went to bed and got up this morning and cleaned the ICV and DISA real good. I had to come back in for a second and look at Jake's video again to make sure I knew which nuts/bolts to remove for the ICV. Got it all taken apart, cleaned, and put back together in about 3 hours. Replaced the air filter as well. Such a big difference! ....all but the new car smell!

I hope that you can help...

I followed the instructions and everything worked out just fine. Like user cesmoot, I had a problem with clamps being upside down, but I got over that challenge eventually. I finished it all, reassembled, and turned on the car, and great it worked! No more stalling, shaking...

But, after a couple of seconds an icon came on next to the P sign, an toothed circle with an exclamation sign in it. I looked it up, and it stated that the system found malfunction in transmission. I never had a problem with transmission.

I drove the car to the BMW shop, but it was close. Car shifts, but it jerks and does not behave well at all. I checked all the connections, all seemed fine.

Any suggestions to what might have happened?

Double check the connection to the MAF. If it is loose it will cause a trans fault.

Thanks, smolck! It was MAF sensor and I had to replace it. I must have damaged it in the process. Also, this is a very expensive part, $550 at BMW shop and $300 at Autozone. I got mine on Ebay, but the point is: be nice to your car parts

Thanks again!

I have a 2006 325i, and it shakes/vibrates when i come to a stop. My dad thinks i have to clean out the idle control valve, so i called around the some mechanic's and one of them said my car doesnt have an idle intake valve. Is that true?

ICV or idle control valve is there on all e46's
The person you spoke with is not a mechanic.

I'd tell you more, except you're not going to do the work are you?

Plenty of info by searching, and youtube it.

2006 is not an E46 unless a coupe, but I assume it still has an ICV?

This Video

This video provided me with a huge sigh of relief. I bought my BMW 2 weeks ago, everything was fine and then on cold mronings it started to idle rough, and then it started at stop lights and some times would cut off at a light. I had to keep a foot on the brake and gas. I saw the video and checked for that hose he said was off. Mine was connected it but I heard this loud whistle noise so i new air was escaping somewhere. I started to feel aroudn the hose an low and behold there was dry rot at the connection point. As soon as I put pressure on the hose and pushed it up some the car's idle balnced out and the whistle was gone. So now I am tasked with replacing the hose. I do have one question. Could this bad hose be what set off a bad catalytic code?
