The steering is light without coding and I’ve used my own tensioner but i have used the belt that you linked!

And i had to remove 1 pulley from the middle the tensioner is the same as you listed but a different part number but it is exactly the same

This is awesome!
Definitely motivates me to do the conversion on my n54. Do you have any steering related lights on the dash?
If everything works, then what benefit is there to do the coding part…

You'll have same VIN as your car, and also without adding 1CB there potentially could be problems when some error occurs - you have additional light on dash that will light up when error show. So coding is more for integration of EPS into the car, but also for changing characteristics of that

Hey great write up. I tried tackling this myself and wired the rack to the car temporarily (while it was still off the car).

I can’t connect to the EPS module. It’s not showing up on INPA. Tool32 won’t connect either.

I’ve coded FA on NCSExpert - #0910, $1CB, $216 to CAS and FRM. But EPS isn’t listed as a module on NCSExpert.

I’ve got a 2006 E90 335i with N54 and these never were released with EPS. I thought that I should still be able to connect to the module using INPA or Tool32.

Any thoughts or do you think it won’t work because it was never released for the particular model?

Check if the CAN loom is wired properly. When connected it should be showing up automatically. Electronics in E9X almost stayed same from 2004, so this is not a case. Maybe there is a problem with mismatch pins in the EPS socket? I can paste the wiring pinout if you want.

hi
just wondering if you would have the part number for the new accessory belt you used

cheers

It's 11 28 7628651 - 6PK1827 for N52.

Hello amazing thread, im attempting to do this on my e92 335i n54, removed eps from e92 320i i see you sayin there are only 3 wires to connect in the ecu box, my eps harness has 5 wires do you have any idea what to connect where?

Have you got a pic of the plug side? Weird because the 2 twisted pairs are the same... PT-CAN lol

As I see in ISTA wiring diagram in EPS socket PIN 1 is CAN (Wake Up line), PIN 5 (PT CAN High (PT - Powertrain)), PIN 2 PT CAN Low. I have checked pre LCI, and LCI and all diagrams are the same, so I do not know why there are two PT Cans in one socket.

Steering angle sensor?

Nope, I'm talking about the socket that is coming from the "outside". Steering angle sensor is connected directly between sensor and EPS module on the rack itself. Socket that has to be done by Yourself has to have those 3 wires (wake up line, and 2 pt cans). You can connect that into DME Box. (This socket has 6 pins, but 3 are used and required as I mentioned earlier).
