Hi everyone,

i swapped not long ago a n54 to my wagon 328i e91 but i still have some issue with the tranny ,

i swapped the following to the wagon:

n54 engine and tranny, all engine wire harness in the engine bay,

full exhaust from 335i that fit perfect in the wagon,

all module swapped except the footwell since i don't have hid light on the wagon and the junction box.

the wagon did not have the steering wheel with paddle shifter and we swapped it as well. to the wagon.

everything works excellent except that i don't have DS mode or paddle shifter working yet. manual works up and down, but if i am in manual only works with the shifter not paddles and after few second will go to d mode by itself


are any differences with the wire harness from the 335i sedan 2009 to the 328i wagon 2009 ?

thank you all

You're a brave soul. You might be the first to do this swap.

I would post this on N54tech. Should get a lot of attention.

Great job !! Can you please list all installed modules with INPA and share the output?

E90 -> Select E90 -> Functional Jobs -> <F2> Identification

Wouldn't a standard transmission be easier to swap?
I love the ZF-trans but for simplicity and headroom for modifying it more.

I hope you post some pictures, the E91 335i is one of my favorite cars. I hope you can find someone to help

here are some pictures of the wagon, i put downpipes today but is giving me a lot of trouble and misfiring in 123 cylinders, i think i have to add 02 sensor eliminator for the o2 sensor after cat converter.

if anyone know what to do with that problem will be greatly appreciated.

[Flex68]

The dp issue might be due to the 02 sensors do you have a tune ??? Jb4 can eliminate the dp 02 issue .... But no idea on tranny issues

yes i have jb4, how do i eliminate that issue with the jb4?

[andrey_gta]

OP is a hero! E91's are pretty

[shadow191]

Your transmission issue sounds similar to those who break the wires near the shifter and lose DS mode. Have you checked all the wiring to make sure nothing is pinched or shorted?

And JB4 isn't going to fix your misfires. It will autoclear codes generated by the downpipes but if you're misfiring, that's another issue. An O2 sim won't fix it either. Are you sure you didn't swap the O2 sensors when you installed DPs? That's a pretty common thing to do and it will cause problems. Are you getting misfire codes? Or is the car just running poorly?

I'm so jealous of that wagon.

you probably switched the o2 sensors when you put them back on, check that first.

Great job on the swap! Ironically, I was cross shipping an e91 and e93. I ended up with an e93 manual.

I did check all around the shifter and nothing broken, not even one wire , has To be something with y the wiring harness deferences from the 328i To 335i.

First i try to swap plug for the o2 sensor at he top of the engine and I found that that my guy put hen incorrectly even tho I said a thousand time to double checked them before remove.
One of them was damaged anyways and I end up hanging both pre cat sensor, almost 500 bucks there for two sensors but solve the problems!!!

lol...not the first bud. Although mine's not a wagon but i did this swap into my 330i last year and it had tranny issues as well. I didn't even get the chance to enjoy it as some lady ran into me and totaled it 2 weeks later. Congrats.

[328iwagon]

i am glad to hear that someone dif this swap before, it is pretty straight forward is you get all the parts from another crashed car.


i still with the same sport mode, ds mode problem.

i even code the tranny again, i did the allophone flash but i does go into ds mode, when i move the shifter to the left, the m/s light lights up but won't show it in dash as sport at all and you can notice that the sport mode does not engage.


i change the shifter assembly as well, i think i did everything except to change the solenoid valves in the mechatronic.

it will be my next thing to do. if any one has any info how to change them, please share it if it is possible.



thank you

Love the swap!

Your wiring needs work. Been there, done that. ZF trans needs two extra wires compared to GM trans.
