Steering wheel tilt / telescope function not working. Need diagnostics help (INPA)

[gjvah]

Hello guys,

Have an 2006 and both telescope / tilt functions are out. Issue started when I swapped in e46 M3 seats, so I thought it's the memory module/controller that was the issue. Picked up a seat memory module, but the problem persists. I'm assuming the new module might be defective, since the chances of both motors dying at once without warning (no clicking noises or anything of the sort) are slim.

Checked the tilt switch on the steering column using INPA and it does detect all 4 switch positions.

Issue 1 is, in the "read position-counter" for the seats and steering column, the both the "steering column axial" and "steering column radial" values are at 0.

Issue 2 is, I can move the seats using INPA, and they respond correctly, however when I try to adjust the steering column, instead of the column moving, the driver seat does

Any feedback much appreciated. I'm going to pick up another seat switch in the meantime. My understanding is that the e46 and e53 seats were interchangeable, but if that's not the case I guess I gotta start looking for new seats as well.

TIA
