excellent info! Ive been chasing down issues on my van for YEARS.........and finally have come to a loose/not sealing oil cap (and oil filler tube grommet at the engine is cracked, leaking air) creating a LEAN condition.....leading to more fuel injected.... and fouling the spark plugs and O2 sensors!

Excellent! My 07 v70 burnt the AC compressor solenoid. After replacement it idled at 1500rpm and very sluggish throttle response. Turns out the fuse #11 was burnt. Thanks for great guidance

M54b25. My old Siemens and Atec mafs are showing 3,22 and 3,3 g/s at idle and I have Lean codes p0171 + p0174. With a new Siemens(VDO/Continental) it shows at 744 rpm 4 g/s (14.4kg/h) and no codes. So I have almost 50% more air consumption as you. Trims are perfekt. How is it possible?

Sweet good job.

I'm sure you know this, but there's a routine for checking the transmission fluid level. Drive the car in your hottest temp and then park the car and shift through all gears with 3 seconds in between. Wait two minutes and then check the level!

Thank you for sharing! This will help me check my volvo!

Same colour as mine, even the VIN is the same for the first 7 digits!

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?

The highlights of this machine👍. Just bought this car and trying to locate the Engine number for registration purposes.

great video...does this heater control valve also responsible for cold air? .... from Mzansi.

Can you please tell me what is the part numbers for hoses that are connected to it ?

Thanks for the video. I will save 70€!

Hi what happens if that check valve is not working correctly do you get a vacuum leak also?

Your awesome I love you 😂 I been searching online for an explanation just like you gave in the first 20 seconds with the picture

It Is to keep your engine as hot as possible for as long as possible after you shut It off so It might be ready for you within an hour or so to take off and withstand higher load without waiting. Tho theres also version with pump attached to It that makes It also circulate hot water so you can keep heater on inside the cabin even when your engine aint running

ja wann kommt denn das nächste Video

nice :)

Apparently it takes a few hundred km for the VANOS seals to seat properly.

Basically the same issues for my e46 last year. Brakes and lights.

It's all doable stuff. Nothing that should keep a car like this off the road for too long 😊

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. 😂

Nice work mate! thank you ♥

Hello sir , I own a BMW e46 320ci and I have some problems with it ! Is there any chance that we can talk somewhere private and maybe you can help me out fixing it !

Thanks for this video, I will be doing this in my 2004 E46 325i. Your attention to detail and knowledge are superb. Liked and subscribed!

I have same problem but with v50but i cant find a fuze? Can yall help

Thank you so much for this video ! I found your video while searching for a solution to my problem. My 2005 e46 325i does not blow warm air thru vents, only cold air.

the thin hose where does it lead that you repaired first

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!!

Thank you, for this video with a lot of information about the entire vacuum system, I will do the same for my 03 X5

great explanation. SUBSCRIBED

Hi, if i delete the secondary air. Can i remove the check valve and plug the hole from the intake? And can I rmove the vacuum control valve as well?

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

great video! i see that some people completely remove the SAP system. do u think thats a good idea?

A cosa serve quella valvolina di plastica collegata si tubi di silicone? Il meccanico lo ha sostituito su mia subaru xv diesel, al minimo faceva un suono simile a questo: brtbbrrrt

Which brand was the best in fuel consumption?🤔🤔

A quoi sert cette petite electrovanne noire

been looking everywhere for this diagram. Nice man

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?

Salut jai un soucis. Avec un tuyaux celui qui et sous ladmission sur une espece de bojte noire il y a deux sortie sur cette boite qui dois etre relie pour la depression celle cote pare brise elle branche vert la boite a fusible mais lautre et branche aucune part ??? Merci beaucoup 🙏🙏

According to technical data this 15min valve off is to avoid overheating of the passanger compartment for short stops. If you are going to fill up tank, engine off - when valve will be open heatcore will fill up with hot water and just after starting car again you will have a hot air blow. So, to avoid it, valve stays close to prevent of mixing water from heatvcore with engine water. In e46 there is no "rest" button on heating panel. There is no single function to control cabin tempereature when engine is off. And to be honest - e9x, e6x, or even e39 - with "rest"button - all of them to allow of adjusting cabin temperature when engine is off - they are using additional electric water pump and stays valve open/closed depends of needs.

The reason is that the valve is to help the passengers stay warmer even when the engine has stopped, its more of a comfort thing, i noticed when mine wasnt working properly as the cab heating instantly goes cold after shut off 👍🏼

Salut es que ca un lien avec la vamne disa ?? Merci

Had the same problem but not that bad, still there was a small vacuum leak. Bought the new cap and it is really bad quality, i then looked for another one from SWAG, genuine one for early engine models with round shape. It really was better hope it will last long from now.

I hear that the oil on the k&n filter can damage the MaF sensor. Is there any truth to that?

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…

I been thinking about doing this at the dealership and I don’t know which of the hoses are broken

Does anybody know the size of vacuum line for the green diagram from the air pump to the vacuum control valve

Does anybody know the size of vacuum line for the green diagram from the air pump to the vacuum control valve

This video ist just perfect - it's simply explained, it's on to the point, it's not too long, it's not too short, and everybody can do it by itself. Excellent work! The world of UA-cam and DIY-ers needs more content like this.

How long vacuum hose needed to replace all of vacuum lines?
