Electronic Power Steering is violent and erratic after motor replacment

[Ciosorn]

I hope so, at least I just have to swap the rotor between the two motors.

If it is coding, I don't know how to check it

I purchased it from an outfit in the the UK that represented the part as "new, old stock".
So I assume the part is intended for UK RHD.
Anyone know if they would be a different configuration from a US LHD part?

When you look at the motor it has two sets of bolt holes which I assume are for left and right hand drive

My EPS Motor does have 2 sets of bolt holes, and did come from the UK. (My car is US, LHD).

@CarnieZ4
I have the same issue as you, but opposite:
I have a RHD motor on a LHD steering rack

If you want I can trade you my motor for yours, so that we both get the correct one c:

Ciosorn,
It sounds like we have an identical configuration. My car is US, LHD, my EPS motor is UK, RHD. I would be have been happy to, otherwise.

@CarnieZ4
Did you manage to fix the issue? Or is it still like this?

[Ciosorn]

I was also thinking about swapping two phases of the motor to electrically invert the direction of rotation, hoping that this would fix it.

I will update this evening and do a recap of everything so that it is left as a resource for everyone else
