3 years later man is still liking comments, what a legend, batteling p0012 code, changed everything, those filters are the last hope! Rpms jump to 1200 after every start up, hopefully it works, much love from Cali

Hi George, I am an ex vehicle mechanic, I was on the spanners for 32 years before i moved over to vehicle collision estimating, 3 weeks ago i bought an E86 with the N52 3.0 engine, I was looking at Datsun 240/260Z S30's for stupid ££ and suddenly realized the E86 is the 2000's equivalent so i had to get one being like ££ cheaper and they don't fall apart with rust issues! It is my first BMW at 61 years old!! I've been out of car mechanics for a long time but the basics never change, I just need updating! Your content on repairing the N52 is top notch mate, I've saved all your videos for the jobs i have to do on my Z4 Coupe as you are very methodical and precise and will save me a bit of head scratching! I'm obviously subbed to your channel and you come across so much better and knowledgeable than other so called BMW 'Expert's' on KZfaq IMO. 👌

just got done replacing my two vans and engine no power when starting up revs up by itslf and guess what!!!!! I am going to do these tonight!!!!! hopefully this will cure my disease... Thanks, George!!!!! Much respect dude!!! you are my legend!!!!

Omg thank you so soooo much. I cleaned my Check valves today and my Car runs so much better now. Thank you for your work and that you share it with us

Yes, people replace the Illinois all the time and never check these check valves and still get VANOS codes. Thank you for this video. This video should be posted for more than a solenoid replacement video.

Just a heads up for any bmw e83 owners. After removing the wheel well trim I found myself staring at more metal under it. No opening to access the valves after lifting the car and removing everything. Ended up replacing them through the top with a handy short swivel extension with a T40 3/8 drive

Man that was a big bird that nailed ur fender! Thanks for the vid!

Today done cleaning venos check value … great info.. thanks

A good video as always! I did this 3 years ago on my n52 and afterwards my vanos performed better.

Thanks for the great Video. It really helped me finding those valves although mine were pretty clean.

Thank you very much, nice job! Today I’ve cleaned my N52 engine, 100% solved vanos problem and rough idle

Thanks for detailed video mate, nice job! Helps me a lot.

Just bought a 07 n51 e92 with 100k and it’s been neglected and sat for a while. I’ve dealt with various issues on this car but the one issue that was driving me insane was a pretty major rough idle changed both vanos’s, did a engine flush, changed spark plugs, ignition coils, intake filter, and a shit ton of other things. but then it came down to the check filters and they were so dirty I couldn’t believe it like 20 times worse then in this video. after cleaning them the idles 100 times smoother, it’s still slightly there but I think this car needs to be driven and flushed more. For anyone having trouble on a n51 take out the stupid emission friendly intake and loosen up the coolant reserve. then take out the tire, wheel well etc. it’s a bit of a pain and I had to switch constantly between short and long extensions and use my hands once it was lose but you’ll get it eventually.

Thanks for the vid George, just done mine this morning

Nice content. Not many KZfaqrs covering the N52.

Thanks for detailed video mate! I have experienced that these little valves can make a huge difference! I have used to clean them each time when doing oil change. Anyway now I have decided to change them for OEM ones, what was interesting that old ones (also OEM) dont click if you shake it but the new ones do click

Thank you! Hoping this will be my last ditch effort for a smooth idle!!! Again Thanks!!!!

Good vid Mate. Thank you.

thnx man!

I just done mine George but used an inspection mirror and head torch to do the fiddly bit so didn't he to remove inner wheel arch, removing the electric cables a good idea.

Great video. Thanks

Great video man but I must say I didn't see you shaking those check valves to see if the inside mechanism is free maybe next time you make sure you free the inside mechanism by cleaning and taping on them 😃

Great video, has anyone got a link to buy new vanos check valve?

THNXS!

I'm gonna do it tomorrow for a customer hope it solves the rough idle....thanks great content 👊

Good.job

Hi George, great video again. Very good idear to do a video about this fogoten filters.It seems that the next work will be your front break disc, isn't it?

Hey do u know which code the car threw at u when it was idling rough. Was it a P0012 Code?

gonna do this today... going to try and get them thru the top, expecting to see some nasty valves. I've cleaned the solenoids a couple times and experience much better running afterward. can anyone explain to me how these check valves work? Where is the oil flowing to? (and where is it not allowed to flow back towards?)

I tried to get at these valves on my 2008 528i, but I couldn't get a good angle on them because of body panels. I was able to get the torx on one of them at an angle, but not the other. I was afraid that if I did manage to get one off, replacing it would be risky, it could fall down be be difficult to recover.

What size is the socket you need to remove them please?

Do you remmember size of socket T30, T40 ??? Thanks

What size BMW security torque to remove the check valve itself?

Can someone pls. tell me if the n42b20a has this check valves too???

What size bit did your use?

Okay I’m removing both arch liners and cleaning that crap out !!

Does the m54b22 have this non return valves?

Good video, for those with N53 it’s the same setup just becareful with front wheel liner when taking it out and You’ll need a pretty long extension.

Hi, I watch this video I clean the vanos check Valvs but the probelem is now the car don’t start again, says that the problem is control starter motor clamp 50 I don’t know what to do thanks

Just done this on my 175thou 130i. Had a bit of a rough idle at cold start. Despite them looking pretty clean, the first start afterwards was completely stable. It can be done from above in about 15 minutes without removing anything once you have them located. I used a 3/8 T40 on a 120mm extension bar. Absolutely no need to go removing wheels and arch liners in my opinion.

These can cause a missfire too?

Could this cause code 2a99 on the n52 ?

thank u for the excellent video i didnt take the fender guard off are you using a swivel and what type 1/4 innch or 3/8th drive?

You can get to them after taking the plastic cover off and using a mirror on a stick and the torx on a swivel head 1/4” drive ratchet with a short extension clean them with Castrol Super Clean after carefully taking off or covering the o rings with Teflon grease or Teflon tape, and a few wraps of electrical tape, especially if using brake parts cleaner, electrical parts cleaner (doesn’t really clean anything) or Jet Spray gum-out carburetor cleaner.Naptha works well, (Charcoal lighter)

WHAT IF ONE OF THEM HAD ALOTTTT/FULL OF METAL SHAVINGS AND THE OTHER HAD NONE AT ALL??? AND METAL WHEN I CHANGED OIL

Nice

Hi Great video Sir, and explanation , I have a question::: does the 2013 x5 N55 (3.0 LITRE TURBO) ENGINE have the same 2 check valves or is this just on the N52 Engines??? ty

I just did it this morning, its quite clogged and dirty, after a good clean up with carb cleaner. Install it and take a short drive and I notice acceleration improve at lower rpm.

This is today’s job after cleaning the solenoids 😁

10/10

@George Auster Hi George, would you know how many check control valves are there on your BMW 760Li? and what's the torque spec (unless it's the same torque as this engine)?

I’d just replace them, seeing how it’s so hard to get to them in the first place. They are not that expensive.

Nice good to, know....👍👏

For the filters, is one for the exhaust and one for the intake or they aren’t designated to a certain vanos ?

Might sound silly but did you replace the o-ring? I plan on doing it on my n51 with 145k miles.

Anyone know the part number ? Or actual name of the part? Rang up bmw and the clown behind the desk had no clue. N52

Is this something that requires draining the oil first? Or do the valves not leak that much?

Are they both the exact same part? I want to order new ones. Great video

I have N52, P0012 error code. I installed 2 new cam sensors, 2 new vanos solenoids, new non return solenoids valves, new oil change with new oil cap, and still have the code with bad idle the first 5 seconds when I start the car. Any input?

Ill check mine hope there located the same in my E60 520d m47tud2 . Yesterday cleaned thé map sensor . Changed thé oil 5w30 febi bilstein long life plus . Oil filter and pollen filters . Now it got to change diesel filter ,egr thermostat ,glowplug control unit, clean thé vanos solenoid and the check valves. Did i missed something ? ;-)

Does the 2015 X1 have these filters also?

Can someone please help, I tried removing the check valve and it unscrewed all the way out but it's not popping out. It keeps on spinning at the end. I have no way to grab it and pull it out. I believe the compressed O-ring is still holding it in. The engine is N52. Has anyone got any ideas?

Can i use brake cleaner for this?

i've just changed the vanos solenoids and i still get error code 2A82 when i push hard the gas pedal, at high speeds the error comes back.. what's wrong with it ?

What's the symptoms when vanos filter is dirty??

Bro, both of the non return valves are accessible from the top of the engine without removing anything.

are these 2 both the same?great video

Friendly reminder to ALWAYS use OEM parts for Vanos and return valves! Spend more and save you many headaches!

You could pass for Carl Froch's lil bro

Do diesels have these?

Did you notice a difference?

Doesn't start that well does it ? starter motor ?

👍🏼

just use long L shape Hex key 40 or RIBE m6 and reach them from the top of engine, its not very hard

Which one is exhaust

Is it possible do it up from the engime bay ? BimmetN53

I would have checked for leaks before replacing wheel arch!

Looks like a dinosaur shit in your car. Good video.

If you were supposed to tighten the valves to 15 Nm, you overdid them by clicking the torque wrench additional times. Grab the wrench by the designated area, tighten the valve and at first click you've reached the set torque. Additional clicks are unnecessary as the torque is now more than what it was set. Otherwise good video.

7:25 just a friendly tip - with that many extensions you are losing torque. You'd be losing torque on a single extension depending on the lenght but if you combine multiple then if you set the 15 Nm on the torque wrench then you may end up with let's say 12Nm on the end with that setup. Thermal expansion along with the thinck O ring probably help to keep everything locked in place and sealed but should you ever notice minor oil leaks around your engine block in that area (or the floor where you park) this may be the cause later... alongside with many other sources of course, like the oil pressure switch and what not :D A good idea to make sure everything is allright is to clean the area with brake cleaner thoroughly once you're done and check back on that spot later. 1st check after a week or two to see immediate issues right away but the 2nd check might be a few months and decent kilometers so you have a good running history to compare with. If you're good then leave it and don't go fixing things that aren't broken. Even it may have like 13,68427 Nm of torque instead of 15 Nm but if it works don't disturb the peace :D Again, no hate, just a friendly tip. Happy driving :)

First remove the bird crap. 😂

The first thing you should have done was get that big splat of bird shit off the car.

Makes a Video WHY you should clean them. Doesn't tell you why you should clean them. Dude wtf there's 10 different Tutorials on these already.
