Starter fluid is the old standard and will do the same thing, but is flameable and cost alot more, thanks for the great tip!
Great video i had plans on detail my engine bay and I can also check on vacuum leaks, thanks for helpful info 👍
I'm throwing 171/174 codes in my 05 325ci. I found the intake clamps loose and am now going to do your soap and water trick! I am afraid there might be a problem with the pcv system as it takes about 100 miles to show the code if I drive it hard, but won't code at low RPMs.
I used to use WD40, but it was messy. but worked well. However your way is better as if it is a bad valve cover gasket, it will bubble in the bad spot!
Good job!
Very helpful. Finally going to be able to pin down where my leak it. Thanks.
Thanks for uploading this video, very useful info shared. By the way, your spotless engine gets my nod. Cheers.
I use an un-lit propane torch for the same job. You can really hear the idle change when that propane gets sucked into the leak.
Thanks for the spray bottle technique...My vacum line started bubbling and i noticed the clamp was missing
Great idea...and I clean my engine too!..
Dude !....your awesome
sorry for the late reply I hear it on idle when in drive or reverse makes the engine rumble and when I drive it goes away :( but comes back at around idle speeds
Thanks for the information
Can you do this to find out if the valve cover gasket is leaking air? I have a vacuum leak but not sure if its the re-usable filter I put in or the VCG replacement.
Very good method.
The only problem I have is that you do not have to spray the whole engine to find leaks. First buy the right equipment to make checking for leaks easier. Secondly, you only have to spray the actual connections, fittings, or clamps. But the spray thing should be done as a last resort. Has nothing to do with the idling. The mixture of soap and water is to uncover air bubbles being forced out of a loose connection. Your P-code will give you the specific area of concern, and that's where your troubleshooting efforts should take place. You should also use Mitchell 1 diagnostics to assist.
After all..........God Dammit today's BMW brand/////
Nice video and Good job, it was very interesting. Thank you ///////////////////
Hey. Superb video. I have strange problem with short fuel trims. My engine is BMW M54B30. On bank 1 i got +25-28%, but on bank 2 it is ok 0 to 5%. I know that my oxygen sensor after cat on bank1 is dead. Is this can affect on fuel trims?
MAF is working, I checked rubber hoses and there is no cracks.
Help please. Thanks.
great video
Thank you
Thanks man, very usefull
Hello, i have a 2002 325i, i have the code P0441, when i give it gas, i hear some sort of suction sound only when i accelerate. any idea what could be causing this? will really appreciate the help.
Curious, what code did SES give you? Also, did it turn out to be a air leak? Thx, great vid.
If clamps are not tight on boots that can cause it too givE u a leak?
you have nice cold air intake, can you tell me where did you buy the cold air intake, and how much?, thanks
If I spray around and injectors in my car kill that mean it's a leak around the fuel rail injector
i have a problem with my idle air controll vale its shooting code p1550 can you help i removed the valve its not dirty and its not stuck closed
Thanks alot for the video!
Question for you..I have a 2003 525i and I have a check engine light on with a code of p1349. My car when at idle shakes alot and when you accelerate it doesn't speed up fast, it takes it's time to accelerate. I took off the hoses that connect to the throttle body and saw a couple of "cracks" on the last hose that connecte to the idle control valve but wan't sure about being cracked tho.
Do you suggest anything? Thanks man.
Replace any hoses that are cracked they might be sucking in more Air than it supposed to causing the car not to accelerate when necessary.
Beamer Fanatic E39 E90 ok I will. Thanks!
+repair fanatic my car also have that whistle is heard in your car please it can be? thanks
Hello can I ask you????
I have a car e39 1997 about 80 km I drove down the speed
Good video, however there is no vacuum pump, that's the secondary air pump which blows fresh air through the exhaust on cold starts for better emissions. The valve with a vacuum line on it is however something that may fail.
It blows air into the intake manifold

im having a rumble in my engine bay and a sort of tapping noise coming from the bottom of the engine but only when in drive or reverse and suggestions?
I would need to hear the Tapping sound. There's a lot of moving objects under the engine bay. Like your rectum Pinyan. Do you hear the noise only when driving straight or while turning. ?
my 99 e46 shakes really bad when I start it in very cold weather and when its idling it stops if i turn it off and back on can anyone tell me whats going on
I have a 528i e39 it won't run unless I hold the pedal down and if I let go it drops and takes a while to start I checked timing and reset cams... can it be maf sensor or the vanos
D Gibson probly crank shaft sensor
I have a problem with my bmw 2000 528i. when it rains and pluck out white smoke and the foot brake feel as if water does not stop
marcelo salaverria when do you get the white smoke. Have you ever done a brake fluid replacement
I have a 1994 325iS. It idles rough, like really rough. It bounces to 1000rmp just in neutral, falls, then bounces again. Then it eventually stalls. There are no check engine lights or anything, so I don't think itd be the O2 sensor.. I figure its a vacuum leak. Any help or advice? thanks!
Might be camshaft sensor :)
vaccum lines . mine did that and eventually didn't start . fuel pump fixed the problem . changeable in 30 mins by removing the bottom panel of the back seat
+Allan Fox so was it vaccum lines or the fuel pump?
that was kinda funny
Broo how can i link up with you to fix my car?
hi I have a question for you I have a BMW 252i and a few days ago I noticed it shakes when I accelerate and when I don't it stops also it sounds like it losses power is there anyway you can help me out thank you:)
Sounds like you have an air leak somewhere
Okay thank you !!

My 2002 bmw 325i has the same click sound like yours here in this video. I still couldn't find the issue. Feeling frustrated.... :/
SingSai Lor tucking sound is the lifters
Ticking
Hi, my 2008 328xi is shaking like crap and it throws only code 2A82, could it be vacuum leak??
No it a sensor
rpm jumping in my x6 2009 bmw.how i can solve it plz help
Most likely a sensor or an air leak. Is your engine light on
I checked the sensor and air leak there is no air leak and the problem that its not showing me in the computer
I have a 1995 740i which starts right up, but with erratic idle then after a few seconds it'll shut down...but it will start again. Check engine light is on, service oil light is on. Motor has enough oil....I pulled the diagnostics code (1213) stomping the gas pedal, checked for leaks, found the boot cracked, replaced it the boot and didn't help any......help please.....!!!!
Joe Cortez ewerytime you have a fault code and fix it,you need to reset the faulty codes,,look for water in oil or it can be the sensors..remember its a old car so you prob have many old stuff that needs replacement
MAF...taken care of...thanks.....
I have a 2009 BMW 528i the idle is low but it doesn't turn off my car . but as soon as I turn the AC on the car shuts off ,have you ever came around this problem
sounds like an idle control valve (ICV.) most cars have valves that allow a little more air to the engine when the a/c is on. SOMETIMES one just needs to 1.) clean the air intake and 2.) clean the ICV.
alguien sabe pq razon mi bmw 328i e46 me detecto estos codigo p0442,p0441,p1423,p1421,p0306,p1183
Dude, ve a Google, look for BMW codes, y te dirán que es y como arreglarlo.
remove the oil cap do you feel vacuum?
Yes, does that mean that there are no leaks?
HELP E90 2005 100+ miles
FIRST RUN:
1. Wobbly / Shaky Car start
2. Engine Light ON, start A/c
3. Jerk on gears but car running
4. Suddenly all functions stop responding no acceleration, no brake response, engine jerk smooth jerk and ENGINE STOPS
5. Check control messages : ENGINE, @, DISC BRAKES, DTC
SECOND RUN:
Engine Light ON but everything responding took car to 120 km/h no problems
Only engine light on.
WORKED DONE:
ECU Change, accelerator pad, valve change.
Please HELP is it sensors??
99.99% it is your alternator. I recommend taking your old one and having it rebuilt. Problem solved
Hey bro my car is running lean what should I do? What should I change? By the way today I turn on the car and drove off but the gears were going in really rough and I would accelerate and the rpms would stay high when I let go of the gas! They will come down eventually I stopped and let the car on and then turn it off and on and it went away!
most likely its your brake booster or ICV

how much would it cost me to have u up here sac everything that u describe in your video is happeining to and my 1999 BMW 528I i spent so far $300.00 on my sensor"s (02) and still having problems i m for real i have been watching you videos on our BMW right now my engine light is sending me this code now could it be wrong (P0150) THANK U
What could be wrong with my car? Rough idling, stalling, loss of power when accelerating. I have same bmw in this video
Maf, plugs, leaks, valves, other sensors or what??
+ogbigc1 yes
Bro did you find out what was wrong I have the same problem
Clean out your MAF sensor and clean out the throttle body. That fixed my loss of power but i still have a leak somewhere.
hey I have another questions for you I took my car in to auto zone because the check engine light came on and it gave me this codes what should I check
P1620
P0174
P0171
I know it's been months but did you ever resolve your issue? If so, what fixed it?
P1188 1189 and I went all around my motor with carburetor cleaner and found nothing
what if my e39 won't even idle?
You must have real bad misfires or real bad air leak.
Check spark plugs and coils.
It's definitely the exhaust manifold. Look at it.
I will
Is there a certain type of soap you use. Just curious
No anyone will do
BMW E39 528I Beamer Fanatics What code did it give you?
It turns out I was missing a component to my air intake.
Ok cool
I always watch you video and I think it is useful thanks but first of all please learn English well,
You need to be smart enough to get It, lol.
Fuck bmw , I had unstable rpm when shifting to D and went to many workshops couldn’t find an air leakage, then finally on workshop discovered the reason and quess what it was ( the torque converter) fuck this car
mohshehri I’m right there with you, I have one had it for years took excellent care of it and it costed me a fortune. I’m getting rid of this POS.
Joey McMahon Jr yeah it’s a piece of shit, It will rip off your pocket
lol omg
Just put ur whole car in river inside of throwing water here and there .what a fool?
