BMW M54 DISA Valve FIXED and Upgraded!

[@JamiesGarage1]

Guys, it’s been a crazy busy Month for me 😮‍💨 but I’m finally getting caught up and I’m excited to have several videos coming to you this month. 💪 Including the SMG to Manual conversation of my e46 m3, preparing my 335d for impact festival, installing bayoptik headlights in the e90, adjustable end links and the f80 competition seat conversion into my e90 😁 For now, here’s a quick video from the chrisfix m54 video where I rebuild a DISA valve to make it better then new! Thanks for watching 🤘BMW M54 DISA Valve FIXED and Upgraded!

[@JoseGarcia-zb3ki]

Would the repair kit work on a N54 2009 335i xdrive or do you know a kit for this platform? Just want to make sure my engine doesn’t get messed up if there is the same problem.

[@Michal_Sobierajski]

Super, że dzielisz się takimi usprawnieniami. Pozdrawiam.

[@JoseGarcia-zb3ki]

Nvm I being dumb the n54 doesn’t come with a DISA valve🤦🏽‍♂️ sorry bout that😅

[@dennisvandegrift9085]

Great video the best I have seen so far on this repair. Do you have a link to the kit you purchased? I’m in the process of upgrading my N52 with the 3 stage and I want to rebuild both DISA valves first. Thanks for the video!

[@sloppy101]

Just bought a disa intake for my non disa e90. I’m so glad I saw this before just giving it a clean and throwing it on. Im coming from the e30 to the e90 and im learning sooo much about these cars. It’s crazy how easily you can create power in these little engines

[@eaglerider94]

Great tutorial! Just rebuilt mine this morning. I carefully removed the DISA valve, keeping it as level as possible when working it out. Come to find out, the flap wasn't functioning, same as in your video "and" the end pin slipped right out. So, yes, be very careful when removing these. I ended up using the German Auto Solutions rebuilding kit with titanium parts. Made sure my diaphragm was in working order and everything worked out perfect. One less thing to worry about with my '03 E39!

[@hooshangmaster]

heh this is pretty useful also discovered a new paranoia since i didn't know the pin can enter your engine.

[@JamiesGarage1]

be scared, very scared! lol

[@YZFMANIAC08]

Just ordered my repair set, looks pretty straight forward 👍🏻

[@terenceclayton8940]

Good video I need to do my e46 disa valve but I didn't know how it comes apart took it off to check it and the flap is loose it can move anywhere it wants to, now I know why my car was hesitating at low revs gonna order a repair kit and sort it out

[@AshtewanPhotoVideo]

Thank you for doing this. Good repair videos are rare and you do great cars.

[@ricky_ricardo]

Thank you this was very well explained. Will def be doing this to my low mileage e46 just to be safe

[@johnautry6851]

Thanks for the great vid. Very easy to follow. I am surprised that the orangy gasket on the flapper frame is not mentioned. Mine is degrading; I'm sure others are, too. If you try to clean it, good chance it will come apart. My o-ring, flapper( prolly original), and crank thingie looked really good. Frame gasket not so. Any thoughts on that frame gasket material? Seem like air will leak, maybe not critical though?

[@SniperFVG]

Thanks from France ... very good tutorial !

[@Yassin-dp4xt]

Hi love the quality of work your provide ! I checked the disa on my 330CI from 2001 and 240 000 km on it. No problems at all. In my opinion it’s impossible in case this pin get lose, that she can reach the motor. And that’s because this pin has no space to move as the plenum is just behind. Are you sure about it ? Thanks,

[@mikemd2697]

The risk of that pin falling out and into the intake occurs during the removal of the disa valve. As you pull on the disa valve to remove it in its entirety, it creates space behind the disa valve... enough space that the pin can then fall out and drop into the intake. The key is to be very aware of the angle while you are removing the disa valve and don't tilt it so much that the pin can fall out.

Well done Jamie 👏🏻

[@bimmerdan1091]

Excellent video

[@JamiesGarage1]

Thank you! 🙏

[@oldjarhead1125]

Nice video! Some kits come with a new diaphragm (cup) for the small valve on the end. It would have been good to show its disassembly & installation.

[@JamiesGarage1]

I've never seen those. The diaphragm is sealed shut so unless its expected to be cut open and glue it shut again, I'm not sure how that would be serviceable. I'll look into it though, thanks

[@brainkill7034]

Not saying it’s written in stone, but from my experience I agree with Jamie in saying that the interior diaphragm of these are not serviceable.

[@j-z75]

Looking to order the kit, but how do I know which O Ring to choose for my 2004 Z4 2.5i ?

[@larryreno8293]

The rebuild does not address the bell crank shaft seal. That can be a vacuum leak source. I think this would be a strong argument fir entire valve replacement.

[@chrisbradley3224]

Great video. Do you have any thoughts on S55 in general or the crank hub bolt capture vs full fixes?

[@seanchu9139]

lack of low end or high end torque? because i am experiencing no power at high rpms, and poor fuel economy but the push at low speeds is still strong (it still kicks)

[@BLACKDAGGER794]

How much do you charge for an engine reinforcement like Chris fixs’ m54?

[@leivabernie]

I’m gonna guess around 5-6k.

[@ricardasr32]

Should the flap be installed in completely closed position? I attached it to this plasti rod and its slightly open

[@brainkill7034]

When new, the flapper is completely closed on the DISA valve unit.

[@Revedance2002]

Is it the same for N52 engines?

[@JamiesGarage1]

N52 doesn't use a DISA valve so you're all good.

[@kurthernandez860]

Good day, can a bad Disa valve cause oil to enter my exhaust pipe?

[@marioturkalj1239]

What is in that big square part of disa valve? Watching this video and can't figure is there some parts inside or just empty plastic cover?

[@xTheMeanBeanx]

What about on a m62? I have a similar sound on mine

[@turt1eforeva]

I’m curious, do you know anybody with a 3d printer because they could’ve used polycarbonate and add a slide panel for the pivot screw for extra security and use the aluminum kit with the flap they sell on Amazon

[@faridb40]

Has BMW fixed this valve on their newer models?

[@barne3668]

fuk no

[@superspeeder]

What about the later N series engines? Are these valves still problematic? My wife’s 2011 2.5L E90 has a loss of midrange torque which wasn’t cured by replacing the VANOS solenoids. I’ve done lots of research and no concrete solution. I don’t want to continue throwing money at it without knowing the cause. Thanks!!!

[@JamiesGarage1]

The N engines don't have a DISA so you're good there. You'll need to have it diagnosed to find the issue. Good luck 🤘

[@meismyname]

@@JamiesGarage1 Unfortunately that's incorrect. N52s (aside from the US 325i) have DISA valves, and the 3 state intake manifold found in the 330i and X3/X5 N52 models have two DISA valves, an inner and an outer. I had to replace both of mine. They're actuated with an electric motor and a worm gear, no vacuum pot. They can get worn out with time, but I don't believe they have the catastrophic issue like the M54s with the pin dropping out. The N52s will throw fault codes for DISA valve faults though.

[@edwinrivera4771]

Does it works on 325i ??

[@otto4399]

i have the symptoms.. but does it possibly make loud noice inside an exhaust?

[@LEGENDoha9876]

i repair the disa valve on my e39 528i 99 and now the car starts but wont run any sugguestions?

[@bgm1958]

Completely off topic but I have a 1989 635 CSi; can you recommend some kind of software that will read the OBD I codes?

[@brainkill7034]

Great question, I would also like to know recommended OBD I readers.

[@TheNizz95]

Hey Jamie i have a bmw e39 with m54b25 engine and it starts pulling after 4000rpm so could it be the disa valve or/and vanos? 175tkm on the meter. The idele control valve gets stuck sometimes but not all the time. Thanks and keep on making good videos 👍

[@JamiesGarage1]

It could be several different issues causing your concern. I'd recommend to remove the valve and inspect it like I show you in this video. You might find something.

[@TheNizz95]

@@JamiesGarage1 thanks, going to check it at the same time i check the idle control valve.

[@brainkill7034]

His tip of covering the vacuum outlet and releasing the DISA valve is spot on. If it goes more than the ~20 degrees or so shown in the video the diaphragm is bad. A DISA valve failing in this manner will reduce power and response at lower RPMs. From my experience, the IACV (Idle Air Control Valve) will get dirty over time and cause surging in idle or something of the like, but typically won’t cause much issue while driving (under load or throttle open).

[@ivanmartinez9074]

Do they make these kits for the M52?

[@waqarqadeer5217]

So is it like throttle body or it is different?

[@JamiesGarage1]

Different. The engine has a throttle body, this is only used to direct the air through the intake manifold for more or less air volume depending on the engine's needs

[@royquesada5295]

Love 'pocket prybar😅😅😅

[@WildDigger]

Can you rebuild the 2 Disas on the 3 stage intake manifold on the N52? The link only shows for the N54.

[@dennisvandegrift9085]

You can install a 3 stage manifold on a N52 engine. They don’t come with it as a stock manifold and I would repair the used DISA valves while you’re doing it. I am in the planning stages of this upgrade currently for my 2008 Z4 3.0I with the N52 engine.

[@WildDigger]

@@dennisvandegrift9085 a 3.0 si z4 does come with a 3 stage manifold.

[@gdubia]

The link to buy the M54 3.0 DISA rebuild kit doesn't seem to be working. Can you point me to where I can buy this kit?

[@mikemd2697]

I literally just ordered a kit on Amazon but I have a 2.5 M54 so it's slightly different ( the main flap is a different length ) so be careful when ordering the right one for your 3.0 M54. I chose not to order the more expensive aluminum kit and opted for the $16.95 plastic rebuild kit, LOSTAR brand that had 100 ratings with a 4.3 star average review.

[@LifeWideOpen780]

Can you do this with out removing the intake?

[@ibrahimmoussa3711]

Sure you can

[@ericgutierrez812]

Yes you can but removing the intake isn't difficult and I recommend doing so so that you can clean it as well as inspect your intake boot and throttle body

[@JamiesGarage1]

Yep!

[@أحمدخريبين-ق9ر]

Hello my friend, I have a problem with TRANS FAILSAFE PROG, and my transmission has become jerky and jerky. What is the solution?

Did you ever resolve you Trans Program issue and is so, what was the cause?

[@traisharmon9765]

Do you know if this kit works for any other m5x disa valves In my case specifically a m52tu Or if the m54 disa would be compatible

[@cheeseburgerbeefcake]

I asked X8R if their DISA rebuild kit was suitable for the M52TUB25 engine in the early E46 323ci and they said their kits were not suitable. I have not contacted other vendors yet, I would also be interested in finding one!

[@HarrryHarrry]

Es ist unmöglich, daß der Pin im eingebauten Zustand aus der Disa heraus fällt!!! Is is impossible, that the axle fell out of the DISA, if the DISA is built-in tinto the intake manifold. Main part of the DISA which fails is the "motor" of it. The diaphragm breaks. So, do not waste money on a kit - buy directly a new original complete one.

[@dougdileo4727]

replaced my disa 3xs in 3 yrs on an x3 m54....cheaply made parts

[@Kamal_AL-Hinai]

of course its plastic

[@1djbecker]

The plastic construction wasn't the source of the failures. It's the design and material selection. The original flap and linkage used a heavily glass-filled resin. Normally a high glass fill strengthens the plastic and extends the service life, at the expense of mold wear. In this case the glass fill acted as an abrasive. If the flap is able to move slightly, it flutters and the vibrating mating surfaces grind away at each other. When loose, the fluttering might loosen the upper metal and start wear there.

[@milk-it]

Why do I get the feeling BMW didn't make this part out of aluminium initially? This check probably isn't even part of their scheduled service policy. Probably designed to fail to get you to buy a new car. Engineered obsolesce.

[@yycsky]

First

[@JamiesGarage1]

🏆

[@ozstriker4075]

Waste of time, the majority of failures (all 3 of mine) are failure of the vacuum pot diaphragm which can't be serviced. You're better of just buying a a replacemt aftermarket DISA unit, they are good for 40k

[@the-real-rg]

does the disa valve on the n52 engine suffer the same fate? if so, is there a rebuild kit for that one? I have a 2010 528i xdrive with the n52 engine and 125k miles. is there a list of things I should do to my engine in order to make it more reliable, like you did to ChrisFix's engine?
