- Shes building boost! Kinda...
In this video we tear back into the E90 335i with the N54.
Were still chasing down this boost pressure issue. I finally got some solid pulls and she absolutely rips! I dont know if we need those turbos after all.
I hope you all enjoy!

Man this car is making for some great videos
I see you got the vacuum canisters great! That charge pipe will go out on ya. That's one thing you can buy cheaper on ebay. But don't buy the one with the two outlets for the Blow off valves get the one with the fake Tial blow off Valve included with it. Should be able to get one for around $150. The boost pressure is a 30FF which is a BOOST LEAK. Or Vacuum leak. But it's almost always a boost leak. So something somewhere is not keeping pressure in the system when you're on it harder. Maybe the charge pipe is cracked but you can't see it like around the "T-Map sensor" at the back of the pipe. There could be an "O" ring or something. Oh and did you move the "O" ring from the old fuel pressure sensor to the new one?? You Must do that. Once the car has all the maintenance done that was ignored for many years (As happens with so many of them because people drive and use them like they're a corolla instead of a luxury sport car) it will be a blast! Plugs are a huge deal on these cars and you're right to get that new set! coils are number two. I'm LOVIN your N54 adventure! I know it's frustrating at this point but you'll get there! When you do. Man it will be so fun when you're ready to do the new turbos and build. I think you should do more on line reading or video searching about this stuff as it's what helps me big time. Try the "Zero to 60" channel! Andrew from that channel has been my role model for my build. I'm running quite the cheap (CHEAP?? lol) N54 build with my 2008 335XI. I've basically built the exact car Andrew built when he had the "17T Turbo build car" Which is what I think your new turbos might be. It should say on them what they are. All the best and looking forward to the next videos!! That fuel system problem is hard to know. I don't think it's your High pressure Fuel Pump HPFP and the LPFP seems to be working so check if you moved the "O" ring from the old sensor onto the new one. BTW you don't actually NEED that adapter. But it should work with it. On and iSTA is great until it isn't. The info in there is old and often doesn't cover a lot of the fixes needed. That's why I said you should do some on line research instead.
N54/N55 (N53 too but only EU market) are notoriously complicated. The HPFP is known to go, easy way to diagnose with INPA. From your problems of fuel codes when demanding max power it could be this.
Observe the pressure on idle, it should hold 200 000 hpa. If you rev to redline, check if it drops below 180 000hpa, most likely HPFP. Take it for a drive and monitor what it does when building boost, it should be quite obvious if the HPFP is dying. BMW dealers are told not to replace LPFP but only HPFP during the recall era.
These value are N53 specific but shouldn't be too far off as the cars share HPFP and injectors (index 11 vs 12 respectively)
When I had my 135 and 335 I had a misfire that turned out to be plugs but coils can also go on these. I replaced the charge pipe for a solid metal one on both as they crack.
Lastly when you park the car overnight, pull the plugs next morning, if you smell fuel then you most likely have a leaky injector in that cylinder which will cause a misfire too. You can check for the adaption values in INPA too. When your reset the adaptations it takes around 50 miles or so to learn. It should be obvious if one or two injectors are out of range.
Hey Alec, great video, keep on keeping on!! We are all holding our breath for this car 😊
I wanted to update you on my BMW E90 with the N52B25. Not sure if you remember, I told you last time that the car was burning a crazy amount of oil, like 1 quart in less than 200 miles. The dealer I bought it from negotiated with me a deal to replace the pistons with the new design pistons. The car is now absolutely cherry. I've driven almost 1000 miles and no oil consumption at all. Really happy with it. I've already done the classic power steering fluid flush on it. Next in line are transmission and diff fluid flushed, and a new radio, because I can't live without at least bluetooth 🤣
Cheers brother!!
Heck yes! I freakin love FCP Euro for the beamahs 😂 It might be a stretch, and I am sure ya’ll probably know better than me buuuuuuut, I am ight 😂 have you checked the O2 sensors. They love to create mixture, misfire, and power issues. Just throwing it out there as a possible box check. Keep rockin Alec. LOVE the porch build as well. It came out super nice!
Nice job Alec
5:00 them BMW feels😢
FCPEuro has that new warehouse in Arizona and it makes getting parts in California so much faster now. I have a hard time going to O'Reilly's or whatever now that I can get OE parts in 3-5 days
I’m in mass and since they opened the new warehouse I’m having trouble getting parts from CT in 3-5 days now, hoping they are just experiencing some growing pains because it’s been frustrating
6:36. not sure about backpressure.
But one sure thing is this valve on the left exhaust is closed during cold start so the cat and Lambda are getting to operational temperature quicker.
Over time, this flap get some wear and rattle as we can listen.
Or sometimes it just get corroded and don't turn anymore (like mine). I left it open and plugged the vaccum line.
Oil pan do not tighten those new bolts too tight if you don't have a tool get them flush with the surface, they will still feel untight, but they will feel untight when they have stretched already and are to spec
I’ve worked on a few n-series engines and those spark plugs are mechanically a one time use plug because of the length of the ceramic portion being fragile and creating exhaust leaks even if they aren’t visibly damaged. A sign of this is dark rings around the base of the plug or grossly deformed/burned coil pack boots
you need to constantly pressurize your injectors to find leaks it takes time for it to show itself
Great video man, this car is so cool! Can't wait to see her buttoned up & daily-able, already doesn't seem a million miles away!
Sounded great when it had some boost! I agree get it running well with boost before spending time in fixing the other items on the list.
Great work Alec!
Great content. Just very pleasant to see you fixing error codes.
My best guess would be HPFP and turbos on their way out.
Wonderfull dog btw 👍
Can’t wait to see you go get some tacos in this car once it’s all sorted!
I had the same problem, turned out to be the MAP sensor causing my lean codes to trip. Give it a shot, it wouldn’t hurt to try to check it out.
plausiblly fuel pump can be interupted by a faulty venting system. the vent tube on the firewall to the throttle body could be culprit
Thanks for the good content Alec, you'll smash the issue!
Good work Men nice job and good details.
What a great video. Happy I came across this as I’m buying a e92 335i on Friday. Will be looking forward to your future post to potentially help me with any issues I come across with my bmw .
Fuel sending unit has fuel filter in it try replacing it’s on the other side of tank
half power icon is injector usually is. a bad hpfp will do it on startup or it could be
So happy mine has noengine issue. still need to drop the tranny. Wish me luck, its Xdrive
Take a look at the EKP module (fuel pressure regulator) behind rear passenger seat bolster purple/ grey module two 10mm bolts. Open casing re install and leave open with ac full blast. These have a tendency to go out when it heats up. But will work till it gets hot again .Sometime the heat sync fails. Use pc fan wired to keep cool till able to replace. Also take a look at the battery distribution block fuseable(under red cover over battery ) links...then also go out similar too EKP. Check for continuity on both sides of fusable links
Great video, I feel your pain chasing the various faults. I’ve been trying for over a year to solve the lean running issue of my e46 330i. Zero vacuum leaks but still running lean & misfiring 😡
Beautiful car. How are you? Hey there, curious to find out about the '84 Kismet?
I have a pretty heavily modified 08 335. Every part of my fuel system was new (spool performance stage 2 bucketless lpfp, new fuel pressure regulator, update low pressure fuel sensor, new hpfp, spool helix overdrive, motive flex fuel kit, new index 12 injectors, EoS BMP4 upgraded EKP module), and when checking codes i would still get the fuel pump plausibility code every now and then. It never threw a light on it's on and the car never ran bad. Not sure what the deal is.
I think it would be nice for you to have a plug tester :) nice you have solved the issues BUT it's not finished yet 💪
I happen to have done allot of adaptation resets in E90's, and I am curious if you actualy did it correctly? It has been a little while but I believe you need INPA next to you with all the adaptation functions and start with the flywheel adaptation, there is a whole guide online on it and it is very important to get it right. In the video it seems you start ripping on it instantly, so you might want to go back, delete them all again and set it up propperly. If you dont do it right the fuel consumtion might get out of hand when you switch to city driving, which can lead to pre-mature failure of parts
Might be the hpfp ? mine was starting fine but as soon as i accelerated it went check engine light. Another distinctive hpfp fault was a metallic ticking sound coming from it when check engine light went on. Open the hood when check engine light comes on and listen for weird metallic ticking
Day off DIY. Thanks for the vids. Question. Do you think it matters what kind of gas you put in the BMW? It calls for 93 Oct but I've been putting 87 for years lol
If you don’t mind me asking how do you get that software?
Every N54 owner;
"Ohhh yeah" ... "ope - half engine light" 🤣
Daily occurance for n54 owners
Some O’Reilly locations price match rock auto if the part number matches
Je pense que c'est l'électrovanne du Turbo ou la sonde lambda
it ain’t got no gas in it
Hi alec,
Loved to see some new stuff from the N54 Lady.
Missfires are often from the Injectors of that model.
The n54 is known for the old problematic inhectors...
There was an callback from bmw back then when they got Sold. Maybe this one got new injectors if not maybe have an eye on em. If they are not vaporizing the fuel good enough then the Mixture fault could be the reason.
The e9x 335i n54 are well known for their high preassure fuel pump and the injectors.
The high preassure fuel pump is not the problem i think because otherwise he would take longer time to start the Motor up.
An indicator for the HPFP is a long taking cold start..
That charge pipe is very poor in these e9x models like friguy4444 mentioned before.
If u find one used on eBay or something get an aluminum one.
Mine blew up 1 year ago and it is a joke what bmw wants to charge for that poor charge pipe..
Spark plugs and the ignition coils should be good ones otherwise these bmw Motors are acting like divas 😅
Ideally the Stock ones
I think it must me the bosch spark plugs and the Delphi ignition coils but i am not 100% sure about that.
Hey at least she did a few good pulls 🙂 it is something 😅
Keep up that good work man 💪
See ya on your next day off 👊✌️
