BMW rough idle? | high fuel consumption? Vacuum hoses replacement & control valve removal

[@flipvdfluitketel867]

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!

Strong work! This video and your sketch saved me

[@stanleyplock1181]

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)

[@catsoandahalf]

Great idea! Thanks

[@bdy_ster]

Thanks for the video and diagram -- perfect detail. Nearly all of my little vacuum hoses are so brittle they crumble when barely any disturbance. Pushing on the clip with fingers was painful but able to do it just as video describes. However, after nearly completing job, I found the 2 torx bolts using a mirror on the bracket that the control valve clips to. Might be easier to remove the bolts with the valve still clipped to the bracket, but already successfully used the finger/unclipping method, so didn't try the bolts.. Maybe next person can try removing the bolts and see how that goes. (??). Like other post, definitely want to remove the cabin air filter and the panel cover on firewall that gives access to the cabin blower to give more working room.

Awesome vid, I plan to do this repair/replace procedure soon.

[@mikegreene4799]

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.

[@Mang046]

Where did you buy the hoses you used to replace the old hose?

[@wanderlust3517]

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.😀

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!

If your car runs better with MAF unplugged it is likely time for a replacement.

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!

[@jviews1]

Tank you very much. very well done.

[@sauliusstanelis5837]

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)

[@BasWillems1234]

Whats the use of the vacuum tank? and how easy is it to replace this complete line?

[@chrismunson5120]

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.

[@jgm113]

Did you have a rough idle on cold start that went away after the engine warmed up when this was happening?

[@thinkinoutsidethebox9078]

You're just replacing the ends. I thought you were replacing the entire line but at least I can use your diagram.

[@DIYTEA]

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.

[@azlakki]

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?

They are available at any car parts deakership. The lines should be standards for air/vacuum and resist to fuel vapours

[@Peter-pv8xx]

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?

Yup, you're right, and i did buy a compression kit. I had the same idea. Just no time with the kids... Will do it soon. Car runs ok, so I'm not expecting TERRIBLE numbers. However, i do feel it's short on power, while accelerating, but that could be vanos right? In any case i have no other 320i to compare with (unless you come and show me).

[@DIYTEA]

@@anjingkampung Regarding the Vanos, you feel some hesitation arount 3000rpm. If not, so its not the Vanos. But it should be done anyway somewhere between 150 - 200k km.

[@wibuwe]

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?

[@cmaximus7627]

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…

[@DIYTEA]

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.

[@DIYTEA]

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.

[@CastlegardCanines]

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?

[@DIYTEA]

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.
