changing E46 BMW fuel injector DIY (M54)

[@mevin2002]

i installed mine wrong🤦🏽‍♀️ didnt secure the top of the injectors to the rail first made a mess will tackle this way another day thanks for showing your technique

[@kellyanderson7115]

If you buy new injectors...make sure they are OEM level parts. Buy from FCP Euro for example. Changing working injectors with Chinese knock-offs is a sure way to open a new can of worms. I just bought a fuel injector test/cleaning machine since I have quite a few cars that are having some service work done to them that requires the intake manifold off, so it's a perfect time to service the injectors. I'll wait for a convenient time to service my E46's injectors.

😂😂 didn’t know you did these kind of videos.. rock on cuz🤘🤘🤘🤘 teach me!!

[@kellyanderson7115]

Note: The carbon buildup around the injector extensions is normal due to the EGR system. Clogged injectors would be either at the tip or internal to the injector.

good work man i have the same car

[@fkbeats6364]

Thanks lot of help

[@colehammond9146]

appreciate the video brother! where did you buy your injectors? any recommendations?

[@jacobc786]

Hi, I have a 2004 330Ci. It is leaking fuel from the injectors only at below freezing temperatures. It always starts/runs perfect and doesn’t leak at normal temps. Is it worth replacing o rings? Or are ‘04 injectors known to leak from the injector body when freezing? If I have to replace injectors do you have to calibrate? Thank you for any recommendations/advice

[@KrisO1976]

I live in a mild climate that rarely ever gets below freezing, so I don't have that experience. I suppose the o rings can harden in cold weather. The car is 20 years old and is likely to have the original o rings. You can buy just new o rings and give that a try. Won't hurt.

Having an issue putting gas in the tank keeps clicking off if you try to put it in to fast. Have changed fuel filter and the purge valve with no luck. Any suggestions. Thank you in advance. Oh love the videos

[@ronaldocrisiano083]

Do a Evap smoke test to find the leak that’s causing it. I had the same issue i changed everything. It turned out to be a cracked fuel pipe under the that leads to the charcoal canister

[@slimm730]

Nice video. Where did you go for the injectors

[@KrisO1976]

I bought them from Amazon, but if you check out the description, I give the correct part numbers. After I changed my injectors, I did a little more research and found out they had the wrong part numbers listed. I had to change them to the correct injectors a few days later.

[@geromelenord4675]

What’s up brother, my e46 are throwing these codes, P1343, P0313, P0300, P0171, P1346 and P0444. On cold starts if I don’t give it a little revs it’ll go into limp mode also. Been trying to figure out the problem for a while now and don’t even know where to start, nothing on google is really clear and doesn’t seem to be alot of help. Any help would be much appreciated man, thank you!

[@KrisO1976]

That's tough. Those are all misfire codes. Could be bad coils. Could just be the intake boots are brittle and cracked.. could be a bad MAF. Could just be something wasn't put on properly during maintenance. I'd change the intake boots, clean the MAF, clear the codes, and go from there.

[@rudyt1582]

Nope I won't be prying everything especially with a pry bar when you can undo clips and fasteners....it's old and plastic might break ....jeez

[@KrisO1976]

Everything is unclipped. The injectors are pressed into place after being there for almost 20 years. You aren't going to just pull them out by hand.

[@46funn]

If you dont put the injector retaining clips back on will you get a fuel leak

[@KrisO1976]

I doubt it. Even without the clips, the fuel rail itself will hold everything in place when it is screwed down

[@AnasAbokayyas]

did you feel any sort of difference in drive after changing them?

[@KrisO1976]

Honestly, no. The car just hit 150,000 miles. The factory injectors were all fine. I'm glad I did it for my own piece of mind, but it was really a waste of time and money. I'm not going to do it to my daily, unless they break

[@smileylocz46]

Where u got the red coilpack caps brother 👌🏼

[@KrisO1976]

Firemotoo ignition coils. I bought them on Amazon.

[@gnomebmw]

I have red high performance BAVauto coils on my '03 E46. For over 10 years. You can get them from ECStuning.

[@TheStianKH]

No need for coding the injectors?😎

[@KrisO1976]

Not on the M54 engines. That's for the newer cars. I didn't have to tune anything either because I didn't use bigger injectors or anything. Just replaced them with new ones. I could have just cleaned the old injectors, but I felt like brand new was the way to go for me.

[@Uliches]

How much cc for each injector?
