E92 xi swap issue (speed sensors) -
04-28-2020, 01:26 AM
Hello,
I haven’t post on here in a while but thought maybe someone could help me out with my issue.
So long story short, I swapped my single turbo e92 335i 6mt to 6mt XI purely for traction off the line. I’m manually engaging my transfer case so the cars awd/rwd with the push of a button. All is great and I’m happy with the results..... except for those damn speed sensors!
Here’s my issue, which I didn’t even consider until after the swap was over, but turns out the front speed sensors are different between the awd and rwd. Awd cars are read off the axle and the rwd is read off the front wheel bearings. I don’t know how to resolve this issue and it’s causing my car to have all sorts of lights on the dash (abs, brake, dtc, and even airbag lights!) and my abs/dtc no longer function.
If anyone could please help me out I would greatly appreciate it!

I wonder if something like this might work too Speed Sensor Adapter - SIRHC Labs (edit nvm... it looks like this doesnt let you change the signal timing... there might be something else out there)
335xi sedan 6mt / MMP 1k turbos / MHD FlexFuel + AIC6 PI / South Bend Stg3 clutch
535xi wagon 6mt / ebay 17t / FBO
Perhaps swap an awd abs module, change the VO to Awd.
You may get transfer case codes, since it’s being manually engaged. You might have to use xdelete so the car does not look for the transfer case signal.
I’m actually looking at the same thing I’m my car, but I thought it may of been stored in a module. My issue is a n52 to n54 swap. The only module that I changed so far, is dme and cas. The donor is an xi, my car is rwd. The abs modules are the same, so don’t bother changing them. We may have total different issues, but brings up a good point why I’m seeing abs and dtc lights. All my sensors are plugged in. I wouldn’t think sensor location would be an issue if bothe exciter rings are the same dimension.
The other thing is, my car is still in the air and hasn’t moved yet. I’m not sure a sensor location would be the issue, it still needs a trigger point.
