Hi! I've question for you. I've got BMW Z4 2003, 2,5L. The problem is that when you push gas pedal hard, car accelerating, but when it comes to 3000 rpm engine goes to "emergency mode" (I don't know what is called, RPM jumps from 1000 to 1500 and back). If don't push gas pedal hard - it runs good. I've change intake pipe already and cleaned idle control valve. Errors shows - MAF sensor and idle valve. What would you recommend to do?

[@CharlesNaidoo-wb4lh]

Will this cause automatic transmission issues. My 528i goes into limp mode and the cog light comes on and gets stuck in any random gear. Please help

I have an E83 X3 with this same M54B30 engine. Your videos are the most detailed and easy to follow of any I've found on the M54. Keep them coming and thanks for the informative video!

[@BIMMERZEITT]

Matt, thank you.

[@willisheydrich1312]

Thanks for Video. Worked for me Thanks again

[@abnerjigsvictoria1764]

Thanks dude. Very helpful.

[@mynameis309]

Was the EGR valve located same place in E83. I would need to do this jobe in my e83 3.0i. Thanks!

[@bimmer6768]

very clear video and instruction. Thanks a lot.

[@SK8TRvsCOPPS1o1]

Just bought a 325i that was quoted as needing this replaced at the mechanics for a crazy high price. With this now I’m just going to buy one and do it myself! Thanks a ton!

[@e36fanatics]

everything on these cars is quoted for insane price... only buy e46 if youre capable of repairing it yourself because for most the parts are fairly cheap

[@LarrySandre]

I have a 2005 BMW X5 which was throwing the 4X4 / brake /eml codes and going into limp mode. The suggested fix to try was to clean the idle control valve. Your video was excellent and very easy to follow. After cleaning the valve - and clearing the codes everything is running great! Cleared up a bit of a rough idle as well! This was especially helpful to me as I am in Mexico and finding a good mechanic with BMW experience is tough!

[@arielschoenfeld5407]

I can’t believe you didn’t start it up at the end. It was still a very good detailed video of how to remove and clean and reinstall the idle valve and it shows removal of the disa valve pretty well as well. Good job on that.

[@dorumarcusiu532]

Used your instruction to solve my erratic idle on my 2002 525i. I had to remove a couple extra hoses to make reinstalling the cleaned idle control valve easier but no big deal. Problem solved! Very good video. Thanks.

[@AfricaTake2]

This guy is the truth. I am in the process of getting a X5 2006 preferably 3.0. With these kinds of videos, I am confident to DO IT MYSELF!!!!

[@chickenpotpie4045]

So my car would start in one tumble, but would die immediately, giving it some gas would help, but the moment you let off the gas, the car died immediately. I have the weird little 6 cylinder M52b20 in my e46, but the procedure was identical on my car. I removed the ICV and it looked clean, there didn't appear to be any real carbon buildup in it, but when I shook it, it was solid as a rock. Sprayed the crap out of it with Carb Cleaner, used damn near the whole can, it took quite a bit of spraying before it came loose, and the amount of crap lodged somewhere inside there that was locking it up was shocking for how clean it looked before. Your instructions are excellent, reinstall was a breeze, would be shocked if it took me more than 5 min for what I thought would be a daunting task. A little water on the fittings as lube goes a long way and makes it super easy to fit it all back together. This was the source of my problem, and your instructions fixed it. I don't think this car has ever idled this smooth, even when I bought it, I thought it was smooth before, it's ridiculously smooth now. Thank you so much man, you've saved me thousands of dollars and endless headaches, I'm so grateful, thank you.

[@indomieforlife]

im having the exact same problem right now, but mine is a 318i with m43b19 engine, do you think it's caused by the same reason? i haven't checked the icv visually though, but the same no idle issue has happened several times and were fixed by playing with the throttle, but i had no luck with it this morning.

[@chickenpotpie4045]

@@indomieforlife if feathering the throttle gets it to run and when you let off the throttle, it dies, then its probably your icv

[@indomieforlife]

@@chickenpotpie4045 thanks bro, i checked the icv visually from outside and theres a small crack visible, I'll try disassembling and cleaning it first if i can manage to get a carb/brake cleaner on my way home (and jumper cables because i think i dried the battery because i was desperately trying to start the car without my foot on the gas)

[@chickenpotpie4045]

@@indomieforlife Check your charging voltage from your alternator, mine died shortly after I fixed the ICV. It could just be a dead battery tho, jump start it and check the voltage, should be between 12.8v - 14.4v depending on the battery installed.

[@indomieforlife]

@@chickenpotpie4045 thanks I'll check that one out too 👍🏻👍🏻👍🏻

[@mosesparedes-gu4bw]

Hi Zeit Thanks for small reply. I’ve recently cleaned my control valve and prior to removal and inspection, it’s surprisingly in a perfect condition the fact that mileage has reached 300 plus for a 2004. This is my third BMW I’ve owned, E36 320i, E36 325i but I’ve always have a soft spot for the first generation X5 especially with the M54B30 version. Just easy to maintain and so reliable. I would like to own a E39 which is what you have purchased recently and the leather seat as you mentioned is in perfect condition. From Australia.

[@vviiper]

Finally! A good video on getting to that idle control valve! Only after watching your video did I realise there was a rubber hose behind the ICV, the rest of the videos had shitty lighting and bad camera angles. I'm going to be cleaning my ICV and replacing the DISA and both rubber boots.

[@BIMMERZEITT]

Thanks, much appreciated! Good luck, the hard work is worth it!

[@pubbiehive]

while you're down there taking stuff off get the fucking crank position sensor as well, thank me later

[@davidg9622]

I'm having same problem with the 1093 code so far nobody can solve this problem

[@eaglerider94]

Perfect turorial. Did the upgrade on my DISA valve a couple of months ago and now it's misfiring when cold so now I'll address the idle control valve as I'm sure it's filled with carbon and not functioning.

[@imTrazeProd]

Thank you SO much! My e60 520i stopped when i put it in drive or reverse and didnt run clean, it hesistated while driving and died if i revved in park. This fixed it! Lots of love!

[@marcusfarhad1729]

What did you use to clean the idle control? Just basic engine cleaner? brake cleaner?

[@BIMMERZEITT]

I might suggest throttle body cleaner these days, but brake clean should be fine if you have that. Anything to free it up when the valve is stuck!

[@code6400]

So it was a little harder work on the e39 525i M54. Because the air intake cannot be divided so simply.

[@ropehitch]

Excellent instruction with concise description and clear images. Nice work. I just bought a 2006 X3 so I look forward to checking out more of your videos of working on the M54. I'm a newbie, hobby mechanic wrenching on my own rides for fun - this type of video is invaluable.

[@BIMMERZEITT]

Congrats on the new ride! I appreciate it, I hope these videos help you out and save you some cash!

[@Doejohnm]

do you need to replace the DISA o-ring once you take it off?

[@HAFGaming]

Best tutorial on KZbin. I was always nervous of this job but after watching this video showing perfect angles of everything I feel more confident. 👍👍

[@tonyquance3737]

Good video. Hardest part for me was getting that plug off. Didn't want to move. Removed it after getting the valve off. Also, hose to manifold stayed in the manifold. Barely a rattle, so I guess it could do with a clean! BMW X5 3.0, showing codes P0172 & P0175

[@robertvanruyssevelt7159]

Thanks for that! Had multiple codes including Idle control valve on my E46 2.2 320i. Cleaned the idle control valve and the disa. Also bypassed the CVS and then had to replace the MAF sensor (got a second hand one from a Volvo - same Siemens unit) and then 1 dodgy coil. Now running like new!

[@tonyquance3737]

While doing all this stuff, it would be good idea to check out the banjo hose to the valve. Prone to cracking on the underside, out of sight.

[@AndyNav1]

Hi and thanks for the video. I just bought a brand new Bosch idler control. When I shake the idler as you show, there's no rattling sound. I tried many times with a lot of hand force, still no rattling sound. Should I return it? Thanks

[@ronfowler9563]

Great video! I'm getting codes p1351 and p1353. I can't find anything on these codes. Any ideas???

[@jaciobe]

What are the symptoms for this needing to be cleaned?

[@mauromoreno3596]

Do you have a vid like this on how to clean your throttle body on this same vehicle???

[@artieward3899]

Great video, clear instructions and camera angles ... worked very well in removing ICV for a clean on my 06 325i Msport touring which started idling rough, running extra lean, no O2 sensor gauge action on startup. Thanks very much!

[@MichaelQuintos]

Thanks, pulled mine out today followed every step. Getting the air box out was somewhat harder than I thought.

[@aqib2000]

Removing the air box is not required

[@أحمدخريبين-ق9ر]

How do you disable the BMW HVAC system from turning on automatically during start up? I don't want it to start right away when I start the car. Turning the HVAC off before turning off the car does not seem to help.

[@edzad5035]

Have a 2001 bmw X5 3.0i and every time I put it in neutral or press on the clutch for longer than a second the engine dies. Its odd cause I don't have idling issues, its only when the rpms drop. If it doesnt die you can feel and see on the cluster that it drops too far and corrects itself. Hoping a good cleaning of this fixes the problem.

[@anthonymaresca4839]

Cleanest BMW engine I’ve ever seen. I haven’t seen many but I’ve seen a few and you got me wanting to clean my engine up

If only all tutorials were like this.. thank you for this. Could this same valve be the issue to car hiccuping sometimes during driving?

[@donnymoore03]

Good morning. Does this video also apply to a 2005 530i E60 M54 engine? Or is the idle control valve in a different location on those?

[@donnymoore03]

Does anyone else know the answer to the question above? Also, does the 2005 530i E60 M54 have a rubber grommet like the one in the video which attaches the idle control valve to the intake manifold?

[@GuynelSaintVal]

does the hose next to the oil stick close to that aluminum threaded hose is supposed to connect to anything? I have a 04 x5 3.0i and mine is loose not connecting to anything. at 5:05 in the video

[@JeLifeCoach]

What’s the difference in this and the ccv valve test? Are both of these for lean conditions bank 1 and 2? How do you know which one to do?

Excellent. Great video angles. When cold at stop light, RPM's drop until ECU corrects. Will do soon. Not critical yet.

[@fjwong7337]

Bimmer Zeit: Thanks for the encouragement. The Disa, icu, and throttle body cleaning job went smoothly; though very time consuming. Would like to share my experience. 1. Disa: the o-ring is not really an o-ring, it's glued on, very tight. Therefore no official BMW part. Some after market vendor in EBay, but O'Reilley doesn't carry it. It's a pain to pick and scoop out the broken (easily) ring, as it split into small pieces. So easier would be to use gasket maker to paste over the existing (flattened) ring. 2. it would be easier to remove the icu with the inside boot removed first. 3. in my case to remove the inner boot hose (with the 2 screws turned downward) was really a pain and tested my patience and lots of time. 4. While at it, why not also clean the throttle body? Overall, it patted myself for a job well done!

[@BIMMERZEITT]

Thanks for sharing your experience Frank, and good work getting it done on your own. No doubt saved yourself hundreds from a mechanic, and is satisfying knowing it was done right by doing it yourself!

[@gail6904]

HELLO DOES a 2008 BMW 328i sedan N52 engine have an IDLE CONTROL VALVE? I know it doesnt have a DISA VALVE..please respond

Excellent video, good job. I will do the same , hope this will get rid of the P1093 code in my 2005 X5 3.0

[@svenlazic]

Great... M52tu has throttle cable thats in the way and also screw on that clamp on my car is angled the wrong way so it is impossible to unscrew. Im writting this in frustration.

[@錘哥錘哥錘哥]

Hi @BIMMER ZEIT , Thanks for you sharing, it is really clear, but after I finish cleaning the valve, it starts to make high frequency noises, and the idle rpm raises( from 650 to 750). Is this normal? Or I break my idle control valve?

[@ufo.architect]

I didn't click the idol control vavle in all the way. Then I started the engine, it ran ruff a couple seconds then shut off, engine failsafe prog light came on, how do I reset it?

[@irfanbeig4800]

Great video, I have a question. Do I need to take it out to clean it Or I I can just spray the cleaner when I expose the inlet of IAC valve?

[@sbrave]

Having a rough idle on start and not great acceleration on my 2000 e46. I replaced the pre-cat 02 sensors, and am now getting a P0340 camshaft position sensor. I wonder if this is why? with your e54, you didn't have to remove the airbox & MAF?

[@Elsiette]

My Z4 starts normally and at idle the rpm remains stable but when I put it in drive the revolutions drop and sometimes when I accelerate and release the gas the car turns off, can this fix it?

[@lorenzodemartini8666]

I've done this today in my bmw and now I have a strange rattle sound coming from the engine. Did I do something wrong because prior to this I never had this noise coming from the engine before.

[@jakedavis6999]

Probably the DISA valve falling apart now

[@agungabsolution]

Why E60 is not included? Is it different with M54 in E60?

[@dabvwm1096]

Changed camshaft and exhaust sensors, brand new oem coil packs. This must be the fix for this rough idling and power loss would you think so?

[@axelgarcia9690]

I have an issue with my 2001 530i giving me only 13 mpg driving mostly in city, I’ve seen people saying the ICV could be causing me low mpg, do you think doing this could help? Thanks

[@carllefong]

How can you tell if the gray rubber tube is inserted correctly into the intake manifold tube?

[@alinajib]

great video man, i was just wondering is it the same procedures for the e60 530i 2004?

[@BIMMERZEITT]

I believe the 2004 530i also has the M54 engine. If so, then yes it will be very similar. The intake boot and air box might be slightly different, that's it

[@the92hoe]

I was removing my idle control valve to clean it, and as i was pulling it out the boot that goes on the end stayed in the engine. should i try and yank it out or should i just leave it and put the icv back on. i just don’t want to rip the rubber boot trying to get it out. Please help asap.

[@edwardthayer9386]

Hey awesome video! I'm getting a P1093 on a 2006 X5 3.0 Do you think that this is causing my code? And do you recommend I clean or just replace it? Thank you so much for your time and help! Ed

[@imestia7911]

Why would you want to remove it? What's the plus side of removing it? I have an E46 320i

[@mosesparedes-gu4bw]

Hi Zeit. Just a spelling correction from the first comment sent- it’s Vanos that I was enquiring if this can be remove and clean. Thanks.

[@BIMMERZEITT]

Vanos can be removed and rebuilt with new seals. Search m54 vanos seals or rebuild kit. They wear out over time.

[@trevinhardinger9868]

Did you have an eml light? I’m getting an eml light and wondering if this fixed it

[@BIMMERZEITT]

I don’t recall if I did, but yes there is a specific trouble code associated with a bad or stuck idle valve

guys When we need to change it and what symptoms ?

[@WizzRacing]

Had one today with the same issue.. The damn plug was not connected to the valve.

[@greynand]

very nice video , change the intake air boot, and now my car wont hold the gas , if i push the gas the car state on other wyse goes off and the light is on any help please

[@BIMMERZEITT]

yo yo boss double check your work my friend; boots all the way on? Upper or lower boot? Sometimes one isn’t enough - the other can tear from moving around during the job. Check that mass air flow sensor plugged in.

[@greynand]

I went to get a reader in the code it say P 1478

[@fjwong7337]

Also in my case, the icv hose didn't come out, as yours did. Maybe my version of the 330i doesn't have that rubber piece. The icv unplug and plug back into a hose that I can see. So maybe 2 versions of icv connection implementation.

[@lynnbourg4970]

I'll try it, trying to solve a problem, RPMs rise, and fall when foot is on the brake.

[@chriskelso4450]

I took my X5 to the dealership for a diagnostics check because it has a rough idle. It smells rich. I was told that the spark plugs and coil packs needed replaced. And they wanted to charge me $1,100 for the job. No thanks! I can do it myself. After installing all new plugs and coil packs, it still has a rough idle. And then I find this video. Just my luck. lol Thank you!

[@BIMMERZEITT]

Thanks Chris! New coil packs and plugs are a good idea too if original, should keep you going another 100k!

[@AdamAus85]

Nicely done. Used this video on a newly acquired 02 525i with a bit of a lumpy idle and can feel improvement. I gutted the DISA before cleaning the ICV though (in preparation of G.A.S. kit), so not sure if that'd change much too.

Thanks for a well edited educational video. Your a confident mechanic with a real talent for for using your knowledge and experience to make it easy to understand what why & how to be extremely careful and conscientious of every step by step procedures that must be carefully performed to do the job correct. I have a question. Will an idle valve on a E83, 2.5, 24 valve straight 6 cylinder with 160,000 miles on it be the reason the engine idles at 900 rpms in park and in drive with the brakes on. I don’t know what the idle for that engine is and I will look it up but I know from the clunk the automatic transmission makes when downshifting 900 rpms is to high.

[@jamiemcdougall8365]

[@syedmoizhusain]

Thanks for the great video. I could get my ICV serviced on my e39 520. You explained very clearly step by step making job very easy. Car is also idling smooth

[@Throughthelurkinglass]

Would this cause long start and random stalling, I just cleaned mine and it jumped up two mpgs, hopefully I'm rid of it!!!

[@BIMMERZEITT]

Sounds more like a failing intake camshaft position sensor

[@erniearambula3525]

With the disa valve removed the intake seems to be openly exposed would it be of any benefit to clean the intake by hand at least areas that are easily reached 🤔

[@BIMMERZEITT]

Not really. More risk than anything.

[@blackpassenger]

great video, many thanks. will a bad icv, or one thats going bad, cause idle surges? i have a 2000 320i with 40k miles and if i let it idle long enough, it will surge for 10 - 15 seconds then normalize. it also surges, sometimes just a few times, after switching off an accessory (headlights, a/c for eg) during idle. few days ago, after driving for about 2 hours in crawling, 2mph traffic in tokyo, the engine suddenly shut down. I was able to restart it immediately with no problem. there were no codes. what do you think?

[@rgus157]

I have an 01 525 wagon with 133k miles. Starts fine, idles fine until the idle rpm comes down to 750ish. Then it kicks a P1343 code. It only misfires at low idle and before the coolant temp is up to normal operating temp. Once the engine is warmed up, it idles fine and the code doesn't come back after I clear it. Can this be a symptom of a dirty ICV? I replaced all coils and plugs with no improvement. Thanks for any advice.

[@BIMMERZEITT]

Check your crank case vent valve and tubing. How old is it? They fail all the time, even new ones. On 99-2001 models the m54 dipstick tube gets clogged as well and can cause issues. Remove it and clean with coat hanger wire and solvent.

[@egarza24]

Awesome video! Love all your videos!! Question, did you clean the DISA valve before you put it back in?

great video would the idle control valve be in a similar location on an e46 2005 coupe ? 2.0cdse? I've got occasional idle fluctuations slight and when I come to a stop it dies it every time but then settles

[@BIMMERZEITT]

Kevin yes the idle control valve will be in the same location on an M54 engine. For European market cars I can't say, we don't get those engines here in the US.
