Do you know if I'll need a new/matching column ECU (like this listing shows: https://www.ebay.com/itm/2013-SUBARU...0AAOSwgn5fQB7p ) or if just replacing the EPS motor alone will not cause any further issues?

I am not sure. I do know that you have to do some calibrations in techstream, it is not a straight forward replacement. At minimum you will have to do a clockspring calibration if you are swapping the whole column. Without reading through the procedure not a whole lot more I can say about it. Sorry man, kind of a shitty deal.

Thanks, I spoke with the dealer, they didn't think I would need the column ecu and the sensor they mentioned needs replaced as well is within the EPS motor, so I really just need the motor.

I mentioned getting it calibrated with their techstream after I installed it and he said that would need to be done for sure, but he's hopeful that with a replacement EPS motor by me and a recalibration at their place afterwards, we might be able to get it resolved without the entire steering column replacement.

A quick look at the repair manual shows reams and reams of possible failure modes! I think there may be more than the whole engine. You are sure it is the motor? The failsafe lists 29 codes alone and not one of them are for an actual assist motor failure.

I am sure of nothing, unfortunately. Dealer said EPS motor and integrated sensor, they could only order EPS motor with new steering column so they couldn't replace motor only. Cost would be $1500+.

Motor is $80 and 2 hours for me to replace at home, so my thought is try that first and take it back for them to recalibrate with techstream. If that doesn't work, back to the drawing board.

I posted a screenshot of their diagnostics on my troubleshooting thread if there might be more info in there that I'm missing.

3M Hella Strong Tape is the brand you're looking for

3m VHB. Also use adhesion promotor for best application.

If my faux pas ends up saving me a grand, sorry for clogging up your thread, but I'll be happy that someone saw it and helped me who might not have otherwise, because I am struggling to get any responses or suggestions in my troubleshooting thread.

FWIW, I think posting in this thread was a pro move. We're the daily crowd and many of us work on our own stuff. Some of us do so exclusively.

That being said, I am at work now. I did see your thread and planned on digging a bit but it looks like @Tcoat beat me to delivering the bitter reality. Your dealer probably just fired up techstream against it and pulled those specific indicators. A compound failure is rare. If I was to believe the dealer's diagnosis, personally, I would dig further into the servo system looking for an intermittent open. Closed-loop servo systems can be notoriously difficult to troubleshoot but one might get lucky finding an intermittent loose connector.

Your choice is to either have the dealer do the work, or snag a copy of techstream and try swapping/calibrating a known good drive unit. This is one of those "if you have to ask..." situations.

edit: I don't think it's the motor. That's usually a hard failure.

Anyone here ever buy a chair like this: https://www.amazon.com/dp/B07G95568C

Thinking of grabbing one for the balcony at my new apartment. I wouldn't be using it for camping.

Didn't find HELLA strong tape, but did find Super Strength Molding tape & Heavy Duty tape

I highly doubt it is the motor as well. As you said they usually work or they don't there is rarely an in between. I knew it was well above my pay grade when I looked up the codes and the page just kept scrolling and scrolling with different sensor, relay and things I don't even know what they are failures!
The last time I "calibrated" a steering rack it involved a torch and a large ballpeen hammer.
I knew the steering was electric assist but damn I had no idea how much data it's control unit was dealing with.

This is on my short list to purchase. All the ones on ebay look like they are going to also have a bootleg copy of the new godzilla v. kong movie on them too.
