All This Work For NOTHING!? E90 N55 8HP Build

- In today's episode, we waste more time than you could imagine! Well not really, but we were working on the infamous N55 engine in my buddy's 2011 BMW e90 335xi.
I guess it wasn't all that bad, it now has good bones but a bad problem. We unfortunately find a lingering issue that's plagued the vehicle for a while now. Not only did we upgrade the turbo with a Turbo Parts Canada unit and install an 8hp45 from an xDrive vehicle, the engine has been refreshed for service.
.... buuuuuut, the N55 gremlins strike again. Stay tuned and see what's developed! Like the thumbnail states, I'm SO over this vehicle. (He should have bought an N54 lol)

Love the n55 👏👏…..
I dropped one in my e46 🫢!!!
Nice!!
ECU capacitor leaking. Open up the ECU to look for leaking capacitors. The way you describe the issues, it could be this.
that's what I'm leaning towards, tapping the DME with a snipe is doing some weird things.
Low pressure and High pressure fuel pump? Check if you have consistent pressure. Regarding the DME, check each of the mosfets if any are shorted. Something silly as old fuel that's gone bad in the tank (too much water absorbed) can also cause issues in general. PS. Love the work you guys are doing, great job!
thanks! I think we're narrowing it down to the DME. we gave it a couple taps and could read it again for codes. I checked connectors and there were signs of water / dirt in them!
Yo these guys hilarious 😂😂😂
Check your DME for fuel contamination or any type of corrosion. Take off all your plug connectors on the DME and inspect and make sure they are dry.
I had this happen to my e70 X5 35D, low pressure fuel line with built in temp/pressure sensor failed allowing diesel through the plug connector which found its way into the DME.
Long story short, needed a new DME, and wiring harness as per BMW for them to cover the DME under warranty.
Taking off the plugs to the DME showed traces of dirt / water intrusion, we saw this and wiggled the DME, ironically it came back to life.
the fact you got diesel fuel in your DME is insane! I never thought that could happen! I'll check as soon as we pull it out!
@@tony.nextlevelrides Makes sense, if the car was sitting outside for a while and if the windshield cowl was damaged or if the drain wasn’t aimed into the fender water could find it’s way to the DME.
You may be lucky, just clean the corrosion, open up the DME itself and give it a clean and you should be good to go.
Unfortunately in my scenario I’m pretty sure the diesel fuel destroyed the insulation on the transformer in the DME for the injectors, everything else on the board seemed ok.
My boy just go b58. I’ve been working on n54/n55 for 10 years and going b58 was the best thing I’ve ever done
into what chassis?
@@frankiewalnuts get a m240i
@@davidhenry4265 No thanks, I'd rather stick the engine in an e90
I've been building my e90 bmw for 5 years. Spent 2 years building it then fell out of love and lost interest after nothing was going my way... funnily enough decided last week to start working on it again
The moment you finish it, even 10 years later, you'll look at it you'll say "damn, I made this".
@@sayan1667 Thanks bro, just started the full respray today in Miami blue...
@@frankiewalnuts That's nice. Make sure you don't destroy the paint when you scrub the clear coat with the sandpaper. I usually use 2000, sometimes even higher before final polishing. Good luck 👍
Loving the channel guys!! Poor Car and owner. I feel his pain as my E46 M3 has now just started going nuts electronically and I can't even start it right now. Sigh..... "BMW". Stands for "YOU GERMAN BASTARDS"!! LOL. But I still love em! Love the shirt too BTW!
they definitely test your patience but not much else drives or performs like them!
Bro I think the. Proplem on the DME crash map file Bro re flash the ecu if yo have mhd tune and jb4 back end go to Factory map and reflash again and check map sensor and the Fuel pressure and Fuel pump connector sometimes it do it like this
we'll give it a try!
@@tony.nextlevelrides I wouldn't reflash in its current state, if it loses connection you essentially brick that DME.
N55 is why
I mean, it could have been an N63 *puke*
Im moving to MaxxECU soon
might be the better way to go! we might consider that if we do an N53 / N55 hybrid engine.
Check the module JBE it’s below the glove box it happened to me it will start then suddenly won’t till i keep it to next day
noted! I'll check that next!
I belive it is the DME IF YOU NEED some help cloning the dme let me know would love to provde and help where I can!
appreciate the help! we ended ordering the adapter to code it, if all else fails, I'll be firing you a message!!
Check the ekp your fpc they are known to overheat and go bad
both are good, at least we could check that off the list.
when you can't read codes, is this for just the DME, or everything? if everything, and the CAN bus is daisy chained, it's likely the first module on the chain, if it is NOT daisy chained, thejn you are losing module power somehow to the entire car,
i know you said you replaced the harness, but have you tried the fuse box? internal shorts in the fuse box can do similar ( seen it on a toyota, and on my Chevrolet beretta, where you could pull every fuse and it would run cause somehow it shorted internally)
if it is JUST the DME for codes, then it is likely the DME is failing when it's internal temp get's too hot, pull it out of the box and put a fan on it and see if it changes anything. ( you can also remove metal cover and put a fan on it. )
seems we're just losing the DME! weren't sure if the CAS was fed power by it or not so narrowed it to the two perhaps.
Really appreciate the help! Awesome thing to look into. I guess my idea of "put a bag of ice on it" isn't as dumb as I thought. 😅
@@tony.nextlevelrides nope not dumb at all, although a mineral oil bath with ice bag might work better LOL ( although very expensive) fan, A/C should work just fine.
Is there a video on swapping the transmission on this specific car? I have the same car and same transmission. I'm looking for a step by step to easy the process.
the coding of an e chassis transmission is going to be the difficult part as we needed to purchase the extra flasher and adapters. perhaps we can make a video about unlocking the transmission with a spare 8hp I have here
@@tony.nextlevelrides That would be great because I am doing a 8hp45 into my 2011 335i xdrive e90.
Bro Did you fix the problem ..!!?
and Did you Upgrade the fuel pump? Because sometime if you change the fuel pump, the wiring inside the pump is wrong you have to opposite the wire I have this issue before I’m done I opposite the wire and the car work fine Be careful for this point And let me know if you have a new update. Good luck, bro.
the repair is in the works! we'll have a video once it's repaired and confirmed.
nope, didn't change the fuel pump or anything, just a very large methanol nozzle. 😉
I dont think this turbo is bigger then the new pure s2,pure s2 had 61mm compressor wheel btw
it's close regardless, I'd have to read up on the specs again. Last I checked it was but either way, we wanted to support a Canadian company, I'm certain it'll make some steam!
What is the 8 speed and transfer case out of?
this one was out of a 2012 BMW X5 with the N55. Factory transfer case was reused.
What fault codes you get when it gets stall?
tons and tons of different codes, one time it was up to 63 and they seem to alternate depending on when it stalls.

Ekp
unfortunately it's not, we swapped it and it's fine. looking like DME.
Hey I live in Vancouver can you help me with my n52 by chance if no it’s ok
I'm always happy to help with what I can. feel free to fire us a message on Instagram!
Issues happen 🤦🏻♂️🤦🏻♂️
sure do, just hate when it's nothing I did and a plaguing issue from the get-go. All of this motor swap stuff could have been avoided.
Hey Tony I know you guys probably have already done this but have you checked for bad grounds or crummy battery a.k.a. shit battery
Already checked and cleaned them all! Wish it was that simple on a BMW :(
25:00 runs on ether? stuff a 1700lph fuel pump in it, their good for 400-600hp on that ethanol junk that has thinners in it that make OEM fuel pumps cavitate. its them and their EPA fuel they sell, not the vehicle. two of the SUM-G3136-2 to pick up feel and shove it into a SUM-230128 with a SUM-250111... the larger gear pumps force it down the line. "tho, does it run on ether, does the fuel rail loose pressure when that happens? 400 or so in parts, free shipping is going on still. ethanol compliance kit up, forced to change equipment because of the stuff they put in gas to demobilize vehicles wandering to far out of their permitted aria!".
the two 14psi gear pumps pick up fuel and push it into a Y block that connects to a filter and high pressure injector pump, can put a 100 micron filter in front of each lift pump. add other fittings and hoses... fuel economy drops off to 60% of whatever it was after fixing it. was 16.8mpg now 11mpg... E100 everywhere. Summit Pumps need to run wire from the battery for each of them and tie a relay block into the ignition for them... annoying federal structured junk just because its not a $140'000 fresh off the dealer lot the pump station switch board operators in the office $300 miles away watching the security cameras give if junk to make it "konk out". looks very new still they don't Karin anymore because its not on their pay role of bill collections.
