Hey man, I started your channel a while ago because of my e46 2000 328i but I sadly sold it a couple days ago and upgraded to an e90 335i 2007. Thanks for your videos you really made my old bmw really nice and I’ll still be looking at your channel so best of luck !

Vacuum leaks with a vacuum in the background ha epic

[@joem3713]

My favorite e46 guy

[@ohiogunna_owagaming766]

Bruh thank you. I been trynna figure out this problem for 2 months💯 keep doing vids bro! You save ppl alot of money

[@EvanGoyuk]

Glad to help!

[@Gexxon]

Excellent this helped a lot. As a new e46 owner (Cabriolet) 330ci in mint condition for only 1 month. I got those dreaded codes and two weekends ago i tackled the job and it turned out to be the exact issues you covered. Rebuilt the DISA and put a new OEM throttle body boot on. Ithad a huge crack in it. I used smoke to find both, and verify what CARLY found and CARLY was right. Worked like a charm. Found them instantly. Oh and CARLY for BMW is a god send and well worth the yearly subscription. Carly found the fault code for both banks mixtures being an issue and running lean. Again CARLY is a GOD SEND. I cleared the codes after the fixes and I have not seen them in over 500 miles since the fix, and she runs smoother than when i got her and gas mileage is better too. Thanks for your taking the time to make these videos bro. They are a big help and much appreciated.

[@EvanGoyuk]

I’m glad you enjoy the product it’s a great thing to have handy

[@GarinKilpatrick]

Thanks for showing how to test a DISA valve at 9:10

[@vokalito]

IT'S JUST ME, or the audio turns off sometimes?

[@EvanGoyuk]

I was having issues with this video

[@grahamcarlson7384]

Yeah dude its just you .

[@nickolasdayz1711]

It stopped at 2:20 and i can't keep the volume to turn back on

[@mcycleserv]

just an enquiry and your vids are helpful ..I noticed a catch can so do you still keep the old system but divert the return via catch can ..thought of doing this so and excess oil is in the catch can and not going back to inlet via vacuum

[@joem3713]

I have this same issue in my daily 330. But ive never had this issue in my M

[@mrdeecov]

I was wondering what size silicone tube you used ?

[@abdullahhamadeh]

Epic...

[@Throughthelurkingglass]

I jist pulled the intake manifold out to change the coolant pipes, now is leaking oil around the manifold, I changed IM gaskets 8 months ago, do they have to be replaced everytime manifold is removed???

[@noeltomas]

What size tube did you get? Is it 3/16"?

[@robertpearson1578]

Hi, i Enjoy your videos. You should get the k@n panel air filter and oil filter, when i installed them on my e53 x5 3.0i and went from 14.7 mpg to 16.5 mpg. when fuel cost's £6.50 a gallon every little helps.

[@arturorodriguez361]

Evan ,,, we have a problem, I hear a leak near the passenger rear wheel and there is agree hose hanging behind the carpet on d rear passenger side over the tire and is disconnected!!!! Where does it go?

[@lew7781]

Hey Evan, I actually have a Mishimoto silicone lower intake boot for a 330 for sale if you are interested.New never used

[@julianmcalister6865]

One helpful question though, what size rubber hose did you use to put on the hard plastic line?

[@JMUDoc]

I would always change the DISA o-ring as well - you're taking the box off anyway, and they are very cheap.

[@bogusienombre355]

Can you please record an audio track to this video. Looks like you had great info to show

[@ersingorkem2518]

Hello,what do you guess if ı've whistle sound when the car pass over red line like 6 rpm, there is little rough idle also, help please

[@elvinnovruzov5775]

Can you show inpa lamda measures when there is a vacum leak? Mine has STFT AT +20 when pressing gas pedal but -10 on LTFT. Loss of power and sometimes rpm won’t drop after releasing gas pedal.

[@the46guide94]

Brother please tell me if you found out your propnelm. Same deal

[@elvinnovruzov5775]

I wish could tell you that. But i think it's because of clogged injectors. i'm not driving it too often so haven got a chance to change or clean them properly. But you should start from those cause i almost changed every part in air/fuel mixture system with no luck. Hope it fixes your issue @@the46guide94

[@benjaminsall3271]

What sorts of symptoms did you have with that vacuum leak? I suspect I might have one but I have checked all the common places and also had it in for smoke test but couldn't find none... D:

[@thomass.jagger2429]

try brake booster

[@JMUDoc]

For anybody reading this besides the OP, a vacuum leak will have rough idle that smoothes out with power, poor fuel economy, and possibly a whistling noise from under the bonnet.

[@JMUDoc]

@Danny Ferreiro Very likely a break in one of the vacuum pipes. 1. Take your air box (and MAF) off and completely seal the end of the intake (duct tape works) to stop any air coming out of it, 2. then remove the brake booster hose (from the servo near the brake fluid reservoir) and blow into it hard - you should hear air escaping from somewhere.

[@jayfox7769]

If it's whistling at high rpm it's your CCV a vacuum line can also cause your cold start to fail

[@bogusienombre355]

Could you please reload this video with sound? Thanks. Need this fix too.

[@terryvideo1]

Loss of sound??

[@mohammadraza3962]

hi, that f connector shown in the video hooks up to the intake boot. where does the other end go to there's two vacuum line attached to the f connector id like to know in particular where the small line goes to I broke mine and it's causing a vacuum leak. also, what is that connector used for?

[@joshhoyle6824]

This might be a bit late but I have the same thing I read that it does to the fuel filter

[@mohammadraza3962]

@@joshhoyle6824 if it went to the fuel filter wouldn’t it not run just stall out. I was told it goes to the brake booster

[@Akiba76]

the big hose on top goes to the brake booster and the smaller hard line on the bottom goes to the fuel pressure regulator, which is attached to the fuel filter assembly and works with vacuum

[@benjourniee9285]

On my 2002 e46 auto sport my secondary air pump is not located where yours is . Help . Please as I have done everything else. Your video is mega useful thanks

Can I send you a picture of my engine bay . As me and my garage cant find the second vacume line lol I have checked at the back of the air intake manifold . Cant seem to feel that hose in that location. Lol

@@EvanGoyuk I have a lot of air vacuum problems. I can upload a small video if easier. Had the car 6 months. It's a nice example. Thank you . Love your channel

[@benjourniee9285]

I have done intake boots the vacuum line on top of intake boot and by the fuel line under the car both ends . And runs much better . The revs dont drop so much when putting car under load like turning wheel while stationary and a little tap on throttle it drops idle . So theres still leak somewhere else.

[@simonjoshua4474]

Hey m8. I do love your videos but this one has way too much of your hoodie and gloves! There's alot of useful comments but it would help to see what you are doing. I really need to do this on my 330ci as I'm getting some leak codes on longer runs.

[@Dougarony]

I have a leak at the canister, the vacume hose has dissolved and I don't know where it leads to. (To replace) Thanks for any impute.
