My Free BMW Isn't Making Boost... Why? 

I don’t see this as a setback. There has been so much progress overtime and I know you will get this baby in pristine condition

Another great video! The fuel problem will for sure be why you can't get on it. If there's not enough fuel pressure to run higher power then it just won't boost requires fuel as you know. I agree with your turbo reasoning. Smoke em! They usually keep working but get seals that leak oil etc. The waste gates don't usually case anything but noise. The rattle everyone cries about won't case any faults.

The more I watch all your hard work to get this car working well, the more I am glad that I sold my 335 and replaced it with a 328. The n52 engine definitely has less power but the design is certainly simpler with less to go wrong and so much easier to work on.

Got an early n54 335i myself in the Netherlands and experienced the same fuel pressure and lack of power problem. In my case the culprit was the old style fuel pressure sensor. Swapped it out for a new style Bosch sensor and problem solved. You need to replace a part of the hard fuel line as well. Hope it helps!

Keep the content coming. Wish you could post more often, one of my favorite channels.

Pipe you replaced is on the suction side not the pressure side, I knew it wasn't gonna build boost still

Great video! I really like the way you explain what you are looking for and doing at each step of the process.

She will become great Alec. Needs just a lot of love. Wish i could help you out more but actually not possible brother..:( I hope you have an awesome Weekend with you family and and some quality father son Time ❤ Take care of yourself and your puppy sage :) See ya on your next Video thank you as always 💪👍👊✌️

Its really interesting to see how you diagnose these issues, and it will be really satisfying to see it all come together in the end:) Keep it up bud!

Let's gooooooooo! Start teaching Sage what tool is for what, will half the labor once she's on deck and not sun baking 🙃

Well that tube you replaced was not on the boost side, that was actualy obvious is would fix the boost. I'd say mount those new turbos on them, fix the fuel pressure fault and take the time to relearn the adaptations.

I love watching your vids before going to work on my own car 🤣🤣

So much fun to watch you. I am waiting on parts for my 2002 e39 530i. All because of your videos I feel confident in doing it myself.

The boost pressure control, deactivation fault is a consequential fault caused by the fuel low pressure sensor fault. The n54 also measures the air by the temperature and the pressure in the manifold; it has no maf, so there can't be a vacuum leak on the non-pressurized side of the intake tract. Hope you can get the car situated soon!

I have a n54, and i reccomend upgrading the chargepipe to an aluminum one and also that plastic pipe that sits on the radiator fan to a 5/16s solid brake line because its very prone to breaking, and the charge pipe is also been recorded to burst under stock boost

Good video once again, keep it going and you'll have a fine running engine!

keep making n54 videos please your content is amazing

Very easy to repair the waste gate on them turbos. Those turbos can be saved considering the mileage

Hey man :) nice dive in there. if you're going to make some DIY in your house, and since it's something you do regularly, have you consider to create another channel for your house DIY?

My car would do something similar turned out that my waste gate actuator rod lost its clip on the outside so it wasn’t even attached long shot I think I got unlucky somehow this happened to whoever owned the car before me but after 6 months of trying to Google and replacing lines finally I found the problem maybe this is your issue doubt it seems like a 1 out of million type of problem

Keep doing the lords work sir! Thank you for your sharing of all your knowledge

Great to see the boost coming.. but I also would verify the fuel system. It's possible that either the lines or the pump is not keeping up with the load. You even got a code for fuel I think, don't you?

Genuinely loving these vids, also informative keep it up

I know this is a 3 month year old Video but i had the same issue and symptoms on my BMW e92 320d M sport, it turned out to be either or 2 different sensors, so i changed them both the pressure converter and control valve by pieburg after that no more issues, pulling like a train!

Liked as always!!

@fcpeuro please sponsor this man with some parts!

oh snap no vacuum canisters you need them they are important

Well at least you have the turbos if you happen to need to use them. I don't understand why they call my car (which is a BMW X1) a twin turbo when it's only one turbo on the car period. I finally got the smoke to quit in my car with some Cata-Clean. I was wondering if you knew with a temp gun pointed on the oil cooler and the high pressure fuel pump how many degrees F it would be? Does around 155f on the oil cooler and HPFP sound about normal to you after the car has been driven several miles? Awesome video man I know you'll eventually get it how you want it.

I am running no vacuum canisters for 2 years. Zero problems

LETS GOOOOOOOOOOOO!!!!!!

Log fuel pressures, lpfp should be minimum 45psi and hpfp shouldn’t dip below 1400PSI full throttle.

Good video bro like always enjoy watching 👀.

Great vid as always very interesting

Why didn’t you get the vacuum canisters from LKQ or a similar place?

👍

Why not an aluminum charge pipe? I replaced my charge pipe for my n55 engine with Aluminum

Keep up the great work getting these bimmers back in the road!

how do you get the Insta Program for the laptop

injectors, hppfp, lpfp

amazing info about the N54 !

another great video brotha! Enjoy your time with your parents.

Im sorry alec, but replacing the intake pipe for the turbo for a boost leak was very low iq of u, respectfully. 30ff is set for boost pressure like you mentioned, so if anything it’ll be a leak from either the turbo outlets to the inter cooler, the inter cooler itself or the charge pipe to the throttle body ( very common). Or waste gates not sealing. As for the vacuum canister delete, it will not affect the solenoid actuation. I personally am running a canister delete. The only symptom you’d experience from a canister delete is loss of brake assist from the booster which is documented to even not be a big deal cuz youd need to be braking, while the car is still building boost, which usually doesnt happen unless you’re brake boosting intentionally.

Help pleases. I’ve been looking around everywhere and I can’t find the reason where the car jerks when hitting 1,500 rpm and then about 3k rpm under load. Any ideas?? I recently bought a 07 328xi e92 150k miles

Really good channel here learn a lot about the N54 set up Tks..

Which l can purchase the grey BMW car but l live in trinidad

Hey man kinda bummed me out this particular video. I don’t know if you did it for the sake of selling out on the smoke machine but there’s a lot of miss information going on and terms being thrown around loosely. You smoke tested the turbo inlets claiming to be searching for a vacuum leak which makes no sense at all for a few reason. First and foremost the n54 doesn’t have a maf and therefore is speed density based. Those intake runners there that you smoke tested and went on and on about replacing don’t effect the cars performance whatsoever. Actually the turbos would function just fine without them, the only purpose they serve is to allow air to travel from a higher up filtered/cleaner source. Replacing them would do nothing to stop a car that isn’t building boost and I feel as if you know this… you keep calling them “charge pipes” and they just aren’t… if you were to have a boost leak it would be somewhere from the turbo to the intercooler or intercooler to intake mani (through the actual charge pipe) into the engine so on and so forth… you know very well that these cars have flawed vacuum actuation based waste gates and develop a rattle where the flappers won’t shut fully thus defaulting towards their normally open state as per their design. This isn’t normal for you and I don’t know why you’re doing this but please “smoke test” your facts before putting them out there in informational videos please. Kindly from one tech to another :)

try to refurbishing the OLD TURBOS...!

The rod bearings crying from the first highway pull and the car not even being warm at all 😭

For all of my n54's and N55's, the first thing I do before anything else is change the charge pipes. The OEM designs are just shitty. Why not just change the wastegates?

Hit up Viv for Viv 19t V4's. Trust worthy

because there from temu

Dude don’t push the car when it’s cold. Wait till that temp at least is above the 160 mark.

BMW engineering. Why do German parts always fail?

Hope you newer work on customers cars 😄😄 I take pipe wil NEVER cause no boost pressure.. and doing pulls on cold engine is just so stupid... 🤦‍♂️🤦‍♂️

Love watching this channel.
