How to TEST your N54 Injectors AT HOME (Leaking Injector Symptoms!)

So only need to remove electrical connector to injectors and disconnect coil pack connectors? Thanks.

I just pulled out one injector just to look at it. I replaced my valve cover gasket a few months ago but when I took the injector out it was covered in oil. Does that mean it was just old oil?

Great video solved my problem with mixture/lean codes. All 6 injectors were leaking for my case giving code 0029e0. Thank you!

It would be nice to see how you coded the new injectors

Should I disconect EKP module and crank it to lose the rail pressure ?

How long was it sitting before you disconected the rail lines from injectors?
I want to avoid fuel all over the engine bay

I've watched this like 7 times this past week prepping for me to to it today 😂 only thing is I'm testing my newly used injectors with bank 2 hard lines so I don't have to pull my 3 injectors that never misfire out of the car, only because I only ordered 3 decoupler and Teflon seals

Test the new index 12’s. I have a set with less than 10000km on them & they leaked enough to spin a bearing.

What u should of done is showed the new injectors see if any of them leaked BS

Thanks for your video

Thank you thank you thank you! For months I've been trying to figure out why I have a difficult time starting my Hyundai Tiburon after I have driven it and it's been off for over an hour. I saw your video last night and did the same test this morning. I found out my injector #4 was dripping gas. Thank you very much

On the bench to check under different modes. sometimes the injector starts to drip after the tests.

So when i change the injectors can what i do mext i dont understand the part with the laptop

You a professional brother, l give you double thumbs-up

Great video. I'm having a misfire on Injector 6 and suspect it is leaking. This video is good info. I never thought to check mine like this. Thanks!!

can you do this for non coded injectors? just to test if theyre leaking.

I have N53 and done the test 4 injectors were leaking, I put new ones and it gets worse now ( 4 injectors was used but I tested them as you did) don't know what to do next:-)!

What Adaption have you reset ? (Name the Adaption?) THX

I did same test as you.. but i have N53 engine.. none of the injector made a single leak, i changed all plugs and coils.. but there are still symptoms like rough idle, shaking, vibrating on cold start, check engine.. i dont know what to do

does it require a new battery program or can you just reconnect and start up?

Im having an issue when i start getting on accelerator at around 3 to 4 rpm the car feels like it jerks n looses power it only does it sometimes .

Do you install new decouplers and teflon seals each time injector is taken out of the engine? :)

good day, this is enough to test the sprayer, thanks for the answer

I did this but my motor never cranked and made an ugly sound. Did I miss somethingv

Thank you guys, it's very helpful video and it just gave me an idea how to test my car injectors.

Will the injector get damaged if i clean it with a scuff pad with brake cleaner on the tip?

e60 535i has no throttle and idels up and down..but mine was not the fuse like in one of your vids .. plz help. new gas peddle , new throttle body. no water in DME ever.

Good testing method.
You should though have tested the “new” ones the same way to actually KNOW if they had the same problem or not.

very good test!

What happens if you don't code those?

Very helpful! 👍🏼👍🏼👍🏼

I understand correctly, after such a connection, nothing can drip? even if i turn the engine

Would this cause oil to smell like fuel?

Hello sir, I also encountered the same situation, is there any fault code? Does the tachometer pointer drop first and then rise after the engine is cold started? car shaking

Great Work mate.
Ultrasonic cleaning might help extend the life of your old injectors and new o rings + filters if they have them.

Did you takeout spark plugs?

I would test the index 12s too. I would also extend one injector wiring to reach each "new" index 12 injector to see if they are open and their injection patterns. Never trust ebay and there are FAKE index 12 out there and when I did what u did last year, I could not even program the compensation number into DME and 3 out of 6 index 12 I bought have the same compensation number.

@thebimmerbarn Hey man, what adaptations did you reset after installing the Index 12s? I've only been directed to, and subsequently did, reset both lamda ones. Should I have done more?

Where can I buy the bmw inpa program ?

You didn’t bleed the lines after you removed the hard lines. How do you know there was pressurized fuel to the car injector. You don’t there full of air.

Hey guys I need help with inpa. I have replaced my msd80 dme with msd81 and was wondering if I should be ok to choose n54 msd80 option on inpa to calibrate my injectors.

nice

The video is awesome, friend. We have launched the 4modes led headlight bulb, would you like to try it? We wanna send it for you to try. I have contacted you by email, hope to hear from you, thanks.

Cool video! Where can I get a car like this?

Well Chris. 6 months ago I purchased 6 index 9 remanufactured injectors. I got a 60k km warranty. Everything was okay. But a few weeks ago the car had a rough colt start again. I checked the injectors and nr3,4 and 5 are leaking. I was warned not to buy remanufactured injectors but I didn't have the money for index 12 ones, back then. The remanufactured injectors were €700. Now I'm saving money again for 6 index 12 new BMW injectors. But the prices went sky high lately. They're now € 2450,- ( $2620) at the dealership. Absolutely insane! Dutch regards, Nico.

Low pressure fuel sencer.

That's the only way to test em and be sure. When I first got my 335 I checked the injectors. 4 wer spraying and 2 dripped. Cold start was fine but a hot start took a while and was a bit rough. $1400 later and the new injectors were in and she was running great. I hope the injectors on my n63tu last more than 100k

This is brilliant, way better than some cleaning services which test the injectors at low pressures.
