When tested at a stand, a 100% guarantee costs $7. I did it yesterday on N43, there are no nets at the entrance anymore. Here they mistakenly write that different revisions are not possible. CAN! I collected one row of two 03, 09 and one 11. You can click on the nickname and look.

These injectors cannot be checked with a multimeter. I set the opening pulse to 150 Volts. Pressure range on the test bench 160-200 Bar

False these are piezoelectric you can’t tell anything this way

Can you check the injectors without removing them?

Wont show a blocked injector but will it?? Just shows its operating

Genesis

You can test the impedance on injectors without removing them from the engine

You are a selfless gearhead. Thank the fates. We couldn't afford our cars if we cannot DIY. Keep up the good work.

would this test the internals for leaks in the injectors?

Do I have to remove them to do this I unplugged them and disconnected my battery let me know ?

Yea but that number is for if its electrically ok not if its spraying messed up?

Great Idea!

Can you measure the ohms without taking them out?

To pull the injector out, loop a piece of rope around the injector and pull. They come right out without plier markings..

Great vid totally helped with my situation!

@ BUDGTM3 ouch that Breather is like $120 w shipping. Yikes I’d of def contacted the company they very well may have done something for ya.. def a shitty design I think the neck that gos in the cover needs to be 3/4-1” longer and needs it’s own rubber seal.

U can just use one of the fuel lines from the rail/injector to lift out the injectors . Doesn’t hurt the line@ all.. Anyone planning on doing n54 injectors don’t sweat it it’s CAKE. 🎂 🍰!! Be sure to code new #s tho to the car..

Index 11-12s can only be mixed w ea other. Index 1-10 can *NOT* be mixed w 11 or 12s. As the 11-12s are entirely different internally.

One of my bicycle tools threaded perfect like inside the bedals or bottom bracket pusher ehh. Previous owner did 3x index 12 then 7 9 9 why? Strange also my line air water trap also threads on… heheheh nice handle (compressed air tools)

Love from portland or haha

If your injectors are less than index 11 you might consider buying a set or half set of index 12’s. One thing the DME requires is that all 3 injectors in each bank are the same index. It’s actually okay to have different indexes in each bank so long as all in a bank are the same. Don’t forget to recode your new injectors also. Also, N54 injectors are piezoelectric, not a coil like all other injectors, so measuring resistance might not tell you much of a story. Lastly, due to ridiculous prices these days, you might have luck sending them out to get cleaned and renew the piezo stack instead of buying new.

It’s 28 min long. That’s NOT getting to the point.

Generally these fail at the pintle seat so this check will do nothing for you

Hi you Can’t check a injector like this, you just check your sparkplug is there a black and sotty sparkplug then you have a leaking injector

Awe dude. You don't have any more videos! I was going to sub to you but I guess there's no reason. Too bad I liked your video and you do a great job of talking to the camera. Oh well.

I hear you. I don't want to have a gutted car either. I like what "Zero to 60" has done with one of his cars when he had it fully road comfort but it was a budget build using 17t ebay turbos and everything budget and he was running over 625hp to the wheel. (And not even at it's max potential) . He ran that for over two years and now is trying other ideas to explore and learn as well as teach. But the comfort of it is part of the cool factor to me.

I really like you video. I'll be checking out some of your other ones too.Do you know if the testing is the same for the other lower index number injectors too? Like is it 200 to 160 ish type thing of index 9 or 10's for example? But couldn't you just do this with the injectors still installed? If the battery is disconnected I should be able to test like this without wrecking my seals and couplers I'd think. I don't see why not. Getting those couplers for a reasonable price is impossible! Then doing the seals isn't so simple either so I'd like to not have to replace them all if I can help it.

Why do you have so much positive pressure in the crankcase, to have oil spilling out? You have an upgraded pcv? I have the VTT crankcase breather, works perfect👍

You make it look so easy 😂 A friend of mine has an 08 335i he’s had it sitting for awhile (couple years) he wants to junk it lol told him ill give him 1k i took a look at the car its starts up fine but after a couple seconds the fan turns on full blast. I also pulled the coils and spark plugs out had some oil on them. And the oil smells like gas 🤦🏽‍♂️🤦🏽‍♂️ you as an experienced owner would it be worth buying it off him or should the junk yard be its new home? Lol Thanks in Advance 🤙🏽

Good info man! Have misfire on 3 and 4 after changing my valve cover gasket due to spark plugs fouling out with oil. I've put on new plugs and coils and is still misfiring on 3 and 4. Do you think that what happened to yours is the same with mines? I'm assuming your misfire is solved.. and did you have to recode your injectors? Thanks...

So all you did was replace your old seal on your #5 injector and everything is fine now?

Me too bro me too

this doesnt tell if they leak ?

Can you check that when injector is in car?

They usually fail.by leaking though... they test low if leaking like the piezo element is failing?

Good information bro. I just replaced tow (2) of my injectors after misfiring. I am definitely going to buy that meter and check them tomorrow. Thanks bro...

Any chance you'd sell that extra injector? Lol
