A little tip for everybody: behind the engine there is the panel with the 4 holes to which the interior air filter tray is bolted. You can easily remove this, it is attached with just 2 torx bolts. This opens the compartment with the cabin blower motor. This will give you extra room for your hands and for a small mirror.
My Application 2002 E46 330i. F5 Flow rate, secondary air system, too low, Bank 1 and F6 Flow rate, secondary air system, too low, Bank 2. As an owner of a multitude of BMWs, with one being a BMW Club Racing Race car, this is not my first rodeo into repairing BMWs. Also I am a retire Aerospace engineer. So I am looking for a clear and concise video with information. All I can say is, ... what a Super Video. Really help me to understand the system and tackle the job. The diagram was outstanding! As an Engineer diagrams are the key to understanding. Very well thought out. More presenters could take note of this. No music, excellent, again more presenters could take note of this! No rumbling on, other presenters take note. Just clear concise accurate information. Again excellent job. Hopefully you have other videos, please keep it up!
Thank you very much for this well made and easy to understand video. This is a repair that has been a mystery for many of us. There is no other video that explains and shows exactly where the vacuum hoses are arranged behind the intake manifold. You have saved me a lot of time and and work. Thank you again Sir :)
Your diagram and video of the vacuum ports helped me soooooo much man! All of my hoses were broken back there, so it was hard to tell which line ran to where. After scraping off all the old hose remains, putting the hoses and caps on was a breeze. You rock, thank you!
Thank you 1,000,000 times, this is the very best video on the subject!! Wanted to fix the secondary air system for a long while and this finally allowed me to correctly replace and reconnect everything, no more error codes, all system 100% working!!! Thanks again.
2004 325i Behind the intake manifold is the electrically actuated valve that controls the main valve. The hoses get hot and brittle. It's extremely difficult to access them. Especially the ones that go to the intake manifold vacuum ports. They are way back under the manifold. You can see them with a somewhat large mirror. But it's extremely difficult to maneuver with a reverse mirror image. You can get an exacto-knife to cut off the broken section. (With extreme difficulty). To install the new hose, I ran a pointed coat hanger inside the new line and positioned it Inside the metal port tube. Then slid the vacuum hose down along the outside of the coat hanger. I lubricated the inside of the line with WD 40. (Or any lubricant)
This video helped me fix the vacuum leaks that triggered the 0491 and 0492 codes on my 20 year old 325i. From your diagram I had to replace the green and both pink lines who's ends had completely broken off. Great video!
The vacuum control valve is a pain in the rear! I replaced it on a BMW 323i took me like two hours to connected it since there's no room & my hand is a bit fat lol 😆 but is is double without taki g apart the whole intake manifold ! It did fix the vaccum leak problem !
Saved me lots of time trying to find a diagram. As them hoses come off. When I had to replace the starter. I had no idea that vacuum cap was missing or where that small check valve hose went....It's behind that other one that is capped off...
Bro youre a life saver i was losing mind i checked and changed literally everything. Checked the hose where the connects to the check valve to control goes and it was snapped! Thank you so much!
Excellent, easy to follow DIY! Did both the green & pink lines and figured since I was going in, I'd replace all of the components. I did struggle with a couple of things... primarily the removal and re-installation of the Vacuum Control Valve. After struggling with depressing the mounting clip with my hands, I took a 90 degree pick and utilizing a lighted mechanics mirror to position it, was able to immediately depress the clip sufficiently for it to easily slide out. Similarly, when attempting to mount the new Vacuum Control Valve by hand, I found that using the mirror assisted greatly in getting it in the proper position to immediately snap into place. One other thing to note, was that when I removed the parts, I found that a portion of the old hose was still fused to the hose fitting on the Manifold and I ended up having to use an Exacto knife to cut the old hose away. Fortunately, this was easily accessible from the left side of the engine.
This is the video I been looking for, I need to do the exact same thing to my E46 I have a small vacuum leak that doesn’t allow my car to pass smog in California. Been replacing just about every hose and still, the vacuum leak is there. Thank you for posting this video, I hope I can reach behind the engine and connect those 3 lines. 😂
Great video, I replaced some vacuum lines already... But was going to tackle the ones behind the intake manifold. You just made my job 100 times easier brother.. Really appreciate this video. 💯
2002 325i He is right, you CAN get the vacuum control valve out if you just patiently work at it. And pay attention to the advice of two fingers pushing on the release tab on the valve. BTW I had the secondary air flow too low error (0491 and 0492 codes) ALL the time for months and the secondary air pump was not coming on (took a while to get around to this repair), but just replacing every one of the vacuum lines like here resolved those codes without further problem, and the secondary air pump now works fine on cold start. So the moral of the story is, do the vacuum lines first before even thinking about trying to replace valves, or anything else in the secondary air system.
Thank you for posting this, it is very helpful. I was able to change both vacuum lines without taking the vacuum control valve out, like you said, just being patient and using some lub spray. Just one comment; there are actually two vaccum caps on the intake manifold, one 7 mm (you repaired and reused) and a smaller 3.5mm above the vacuum line that comes from the discharge end of the check valve.
Exceptional breakdown with the check valve and the cat who mentioned removing the firewall plate is a game changing experience for elbow room. Do you have or know of a video feed on replacing the Jet Pump? Not sure how to approach this one. Thanks to BMW, most all the key parts that need replacing is a pain to get to. Excellent video, thank you. Long term fuel trim for bank 2 should return to normal levels now.😀
Hi, really helpful video I found your diagrams especially helpful ,as at the back of the engine it really hard to see want you are doing, keep up the good work 👍
Hello, you mentioned that you have changed the entire hose that goes to the fuel filter. Maybe you could tell me something more about it? Was it hard, what did you have to remove? (I am thinking about changing it, because everytime when i start the car after it was not running for a longer time, it starts roughly (pressing acceleration pedal helps). But if i imediatly turn the engine of after starting it, it starts imediatly. And the longer the engine is turned off, the harder it gets to start it. Thanks for help in advance😁 (m54b30 engine)
Does the vaccum tank has another hose that goes up to the bulkhead through electrical relay fuse box? I see gray hose behind the yellow line. That grey line that goes to the vacuum tank. Where does it attach on the intake manifold? And the other end of the vacuum tank hose (not shown in the diagram) goes to the bulkhead?
You couldn’t of did a better job in the making of this video. I was amazed of where you were able to put that camera. I am almost positive I have a huge vacuum leak going on in that area but it is very difficult to see back there. I can hear a vacuum noise coming from that area though. I also am throwing the two manufacturers codes from my cheap scanner that are apparently vacuum related amongst multiple other things. It’s weird my car runs better with the mass airflow sensor unplugged. Anyway amazing video! You also got my Sub! Your camera work is amazing!
Great video, sir! What brand of silicone spray are you using in this video. I like the flip up feature, not many manufacturers have that feature here in the U.S.. I'm about to replace (again) all these vacuum lines and to include check valve and DISA seal and dealing with a hairline crack at the valve cover on my '02 530i E39. Dealing with those pesky lean codes. Thank you for your very detailed instructional video. Best!
Thanks mate! For the silicone spray I use Nigrin, its a famous brand here in Germany. But any brand should be fine. Good luck with your coming project 👍
Wait so you're telling me there's a vacuum hose that goes all the way into the petrol tank into the fuel pressure regulator from the intake boot??? I just replaced my fuel pressure regulator and fuel filter. There was nipple that seemed like it would connect to the vacuum hose but the old regulator didn't have anything connected to it. So I just replaced the new FPR in the same state but it runs just fine (aside from a vac leak coming from the intake boot)... are 320 M54s different than X3 M54s?
Can't track down the cause of p0171 and 174 on a 2003 530i, I've replaced all the small vacuum hoses they were all deteriorated but no luck, the engine runs fine, I'm also getting a p01863, I've read that a weak fuel pump can cause a lean code, again the engine runs great, I've had to replace the oil filter housing gasket and the oil pan gasket but there is still oil leaking from above, I also did the valve cover gasket, the oil is on the drivers side, possibly the pcv hose maybe?
Quick question just to get a final answer because different sources say different things, but what size tube did you use for the tubes that go to the jet pump, and the size of the tube that goes from the smaller nozzle of f hose? because ive heard 3.5x1.8mm ID, 3.5x2mm ID, and I've heard the size doesn't matter as long as the ID is correct, Please help!!

Where does the bottom hose on the purge valve go to??? I think it maybe on the intake somewhere but I can’t find it! I really need help and can’t find an answer anywhere.
I can just barely touch the vacuum valve clip since I have small hands. Do you think it would be worth while to take apart the intake manifold for better access?
The idea is to remove the valve without removing the intake manifold. It should be very,easy for you as you have small hands 🙂. But to help yourself better, you need a small mirror to localize the exact position of the valve and you will need both hands as I explained that on the video. Just be patient. The pointing and middle fingers of your right hand should push the clip back, and the left hand grab the valve and pull it towards you. But you still cant do it, the only second option is to remove the manifold and its a huge work. By doing this you will need may be to change the intake manifold gaskets if they are old. This option will cost you may be a day of work.
HI I was told silicone of any variety will contaminate/destroy the oxygen sensor, and the amount of silicone needed is minuscule". You should use another spray on the hose.
@@catsoandahalf silicone or other chemicals are definitely bad for the MAF. But here there is no risk that the silicone will get in contact with the hot wire of the MAF.
@@DIYTEA The oil will enter the vacuum system and be expelled into the engine and exhaust from the ICV, PCV etc. You drew it out pink line to the yellow yellow goes into the intake and my end up in the exhaust with the O2.
Why is my check valve underneath my air intake manifold and not behind the engine like your video is? I bought the car and it comes from the PVC valve goes down about a foot. Then I'll have the check valve on and then there's a key going up towards the air and take valve and then into the air blower explaining me why it is a 1997 E36 BMW 328i
Thanks for your videos, I just subscribed to your channel. Quick question if I may. You mentioned the size of the tubing twice in the video, but could you please confirm if it is High Temperature Silicone Vacuum Tubing Hose or is it Cloth Braided Vacuum tubing Hose? Excuse my ignorance…
The vacuum lines are not working under too much heat. They are not in contact with the exhaust or the cylinder head etc... the tubes should be suitable to resist fuel vapors.
Right now I'm fighting a 1188 1189 code on my 2000 BMW 528i but with a m52 engine the only thing I don't have is a fuel regulator line and I just have a l boot but I may just remove my intake
Excellent video. I appreciate your very much. I have a question. My green "hard" vacuum line is brittle. Is it okay to to replace the entire line with regular vacuum hose or do I need to purchase another hard line and just fit on vac. hose on each end like you did. Thank you.
Thanks! In my opinion it is possible,but the hard lines are much more stable against Fuel vapours. You can give it a try, may be it will hold a couple of years or forever.
Where do I find these lines or at least the type it needs to be. I got the size and measurements . Also does the line going to the fuel filter have to be a special type of line ? Please post them in the description.
It is an emission relevant system to reduce the HC and CO during the cold start phase by heating up the catalytic converter in a short time. Also the ECU will notice that may be you will get a check engine light. In addition in my opinion if the catalytic converter will operate under longer cold phases this will reduce its lifetime because during the cold start there is a lot of none burned fuel which lands in the catalytic converter and this is not good.
I dont have any vacuum lines on the passenger side near the secondary air pump, nor on the back of the intake. I only have one going from the fuel filter to the intake boot and from there to the brake booster. I have a 2004 325i . Why Is mine different?
May be in warm areas bmw made models without the secondary air pump which needed to warm up the catalyc converter quickly in cold weather. If you dtill have the pump so somebody deleted the vacuum lines
Hello i have a question if after removing the pump and blinded the valve in the engine block do I have to blind the hose between the valve and the pump?(green line on picture)
I have an e46 320i either and there is a problem with the car My o2 sensors are removed When rpm is more than 3500 i start to have white / black fumes I have oil consumption And a lot of fuel consumption Any suggestions about the fumes ?
So if I delete my SAP I can plug that back vacuum port and get rid of the Vacuum control valve and all the green and pink lines correct? and if I get a different muffler U cab cap off the port right beside that because it goes to the rear to open the valve on the muffler correct?
What is SAP, and can you really disconnect those lines? My car is missing some tubes and also the check valve, the white and black thing. I ordered it now and connected some hoses. Is is bad or should I connect all hoses without a SAP? If I didn't have one installed? Best regards

Replaced all vaccine lines but still getting a Vaccum leak from the Vaccum control valve. Is it possible for them to crack or break or is there a possibility the intake manifold is cracked?
The vacuum control valve could not close properly or could be jammed. You can test it. Take it out and give it 12v and blow air from the inlet and see if it leaks. The intake manifold could be cracked also or the gaskets should be changed. There is another spare vacuum port on it which I didnt show on my video. Check that cap also. There is high chances that it is craked.
I don’t have issue with leak but I have too much negative pressure in my engine. When car is running I can’t take off oil fill cap because there is so much suction. What can be the issue This is on bmw n63 engine
Hallo, mag sein aber 100% kann ich leider nicht sagen. Das Prinzip soll gleich sein. Die Motoren sehen sehr ähnlich aus, z.B mein Ventildeckel stammt aus einem 330i.
@@fal121 verstehe, aber kannst du den Diagramm als Basis entnehmen. Meiner Meinung nach, es gibt so gut wie kaum Unterschiede. Viele AMIS haben hier kommentiert und das Video hat den geholfen. In den USA sind nur 323, 325, 330er unterwegs. Keine 320er

It's extremely difficult to access them.
Especially the ones that go to the intake manifold vacuum ports.
They are way back under the manifold.
You can see them with a somewhat large mirror. But it's extremely difficult to maneuver with a reverse mirror image.
You can get an exacto-knife to cut off the broken section. (With extreme difficulty).

Then slid the vacuum hose down along the outside of the coat hanger.
I lubricated the inside of the line with WD 40. (Or any lubricant)

Where does it attach on the intake manifold? And the other end of the vacuum tank hose (not shown in the diagram) goes to the bulkhead?
You're just replacing the ends. I thought you were replacing the entire line but at least I can use your diagram.
The ends go bad with the time and crack. The rest of the line is from a stable rubber/plastic which you can keep it.

@@DIYTEA The oil will enter the vacuum system and be expelled into the engine and exhaust from the ICV, PCV etc. You drew it out pink line to the yellow yellow goes into the intake and my end up in the exhaust with the O2.
@@danc2014 ok lets pretend its a risk. I did this job since 2 years now and Zero problem.
You can use other lubricant to fit the hoses. Your choice
Why is my check valve underneath my air intake manifold and not behind the engine like your video is? I bought the car and it comes from the PVC valve goes down about a foot. Then I'll have the check valve on and then there's a key going up towards the air and take valve and then into the air blower explaining me why it is a 1997 E36 BMW 328i
I don't know. You have a different engine. This video is for the M54.
Thanks a lot! One question, why did you change only one cup behind the intake manifold?
Because the other one was ok. But you are right,I had to mention that there is a second one at least.
@@DIYTEA 👍
Thanks for your videos, I just subscribed to your channel. Quick question if I may. You mentioned the size of the tubing twice in the video, but could you please confirm if it is High Temperature Silicone Vacuum Tubing Hose or is it Cloth Braided Vacuum tubing Hose? Excuse my ignorance…
The vacuum lines are not working under too much heat. They are not in contact with the exhaust or the cylinder head etc... the tubes should be suitable to resist fuel vapors.
Thank you
Well Done ..
Right now I'm fighting a 1188 1189 code on my 2000 BMW 528i but with a m52 engine the only thing I don't have is a fuel regulator line and I just have a l boot but I may just remove my intake
Tank you very much. very well done.
Excellent video. I appreciate your very much. I have a question. My green "hard" vacuum line is brittle. Is it okay to to replace the entire line with regular vacuum hose or do I need to purchase another hard line and just fit on vac. hose on each end like you did. Thank you.
Thanks!
In my opinion it is possible,but the hard lines are much more stable against Fuel vapours.
You can give it a try, may be it will hold a couple of years or forever.
Brand of vacuum line and thickness?
What ia the size of the pink and gray line? 3.5?
The pink line has also the same size like the other lines I have changed on the video.
The gray line I didnt check honestly.
Relly porfect explain thank you so much
Where do I find these lines or at least the type it needs to be. I got the size and measurements . Also does the line going to the fuel filter have to be a special type of line ? Please post them in the description.
They are available at any car parts deakership. The lines should be standards for air/vacuum and resist to fuel vapours
Can I just remove the Secondary Air Injection Control Valve (including Secondary Air Pump) and seal the hole?
It is an emission relevant system to reduce the HC and CO during the cold start phase by heating up the catalytic converter in a short time. Also the ECU will notice that may be you will get a check engine light.
In addition in my opinion if the catalytic converter will operate under longer cold phases this will reduce its lifetime because during the cold start there is a lot of none burned fuel which lands in the catalytic converter and this is not good.
Would you be able to provide me with the measurements please?

I dont have any vacuum lines on the passenger side near the secondary air pump, nor on the back of the intake. I only have one going from the fuel filter to the intake boot and from there to the brake booster. I have a 2004 325i . Why Is mine different?
May be in warm areas bmw made models without the secondary air pump which needed to warm up the catalyc converter quickly in cold weather. If you dtill have the pump so somebody deleted the vacuum lines
I been thinking about doing this at the dealership and I don’t know which of the hoses are broken
Just change them all
Hello i have a question if after removing the pump and blinded the valve in the engine block do I have to blind the hose between the valve and the pump?(green line on picture)
If you are sure that the secondary valve near the pump is sealed and have no leaks, no you don't have to blind the hose going to the control valve
thank you, this really helped 👍
I have 2004 x5 e53 m54 engine I don't have a secondary vacuum valve in the back of my intake manifold? where else should I look?
You have to follow the vacuum line from the secondary air pump to find the valve
excellent video
I am really not sure how did you do this? It is impossible to reach behind. Did you take any parts out?
Of couse you should remove the particle filter bay
i got that. Would taking engine valve cover help? I need to replace gasket anyway. @@DIYTEA
@@mirnaemir yes will help a bit but not a lot.
I can't believe you're able to reach,work,record even you tube from there
It was not easy, but possible. Recording was done by a gopro.
How long vacuum hose needed to replace all of vacuum lines?
They could last long for years. But I would replace them all 7-8 years or so. There is no rule. Just to avoid a headache seeking for vacuum leaks
I have an e46 320i either and there is a problem with the car
My o2 sensors are removed
When rpm is more than 3500 i start to have white / black fumes
I have oil consumption
And a lot of fuel consumption
Any suggestions about the fumes ?
Install O2 sensors back. Otherwise your car will run poor for ever.
So if I delete my SAP I can plug that back vacuum port and get rid of the Vacuum control valve and all the green and pink lines correct? and if I get a different muffler U cab cap off the port right beside that because it goes to the rear to open the valve on the muffler correct?
What is SAP, and can you really disconnect those lines?
My car is missing some tubes and also the check valve, the white and black thing.
I ordered it now and connected some hoses.
Is is bad or should I connect all hoses without a SAP? If I didn't have one installed?
Best regards

Replaced all vaccine lines but still getting a Vaccum leak from the Vaccum control valve. Is it possible for them to crack or break or is there a possibility the intake manifold is cracked?
The vacuum control valve could not close properly or could be jammed. You can test it. Take it out and give it 12v and blow air from the inlet and see if it leaks.
The intake manifold could be cracked also or the gaskets should be changed. There is another spare vacuum port on it which I didnt show on my video. Check that cap also. There is high chances that it is craked.
I don’t have issue with leak but I have too much negative pressure in my engine.
When car is running I can’t take off oil fill cap because there is so much suction.
What can be the issue
This is on bmw n63 engine
Pcv valve should be replaced
Hi.
Sind die Leitungen genau am 3l m54 wie am 2l m54?
Hallo, mag sein aber 100% kann ich leider nicht sagen. Das Prinzip soll gleich sein. Die Motoren sehen sehr ähnlich aus, z.B mein Ventildeckel stammt aus einem 330i.
@@DIYTEA ich frage es, weil als ich die KGE wechseln wollte, habe ich ein paar nicht angeschlossene Unterdruck Schläuche entdeckt
@@fal121 verstehe, aber kannst du den Diagramm als Basis entnehmen. Meiner Meinung nach, es gibt so gut wie kaum Unterschiede. Viele AMIS haben hier kommentiert und das Video hat den geholfen. In den USA sind nur 323, 325, 330er unterwegs. Keine 320er
