I did have a look at the eps rebuilding services and i think the ECU named one wants at least £310 or up depending on the part number and if it turns out it’s not faulty then they’ll only charge a testing fee but they wouldn’t let me know how much that is so I’m on the fence about it or just selling the car as is. Wouldn’t have minded giving it a little tlc and using it for the summer but that might not happen with money being tight.

I am near Amersham, I can do all the work myself but I do like to only do work that is necessary to fix the issues hence why I joined this forum and have been researching in my spare time to work out what I need to do and if there is any way I can rebuild the column myself! I did sort out my roof motor and now the motor works but there is a leak somewhere as well so that was a waste of time since the roof will never work without at least one new hinge lol it’s all fun and games. Thank you for your kind offer though bud
I’m getting mine ready for another track day. It’s been flawless but I guess it’s time when things need replacing based on its age.
Does anyone have a part number for the eps?

No problem.

It is simpler to get yours fixed by ECU Testing when it fails. Very fast service.AaronMaguire said:
However, if you're looking to have a spare (which would need coding to your car), then if you get the part number of yours ECU Testing should be able to tell you which other numbers are compatible. Post it up on here as a wanted and one of us should hopefully be able to supply a spare one.
Thanks for the PM. Sounds more likely to be a Steering Angle Sensor from your description.enuff_zed said:No problem.

EPS update.
I have just received my car back from the suspension and alignment garage.
I took it in on Wednesday. It was too low for my liking after installing the coil overs myself which coincidentally triggered the EPS fault.
I told the garage this and they reset the ride heights, aligned the car (it was way out, understandably).
The fault code was intermittent during this stage. The garage reset the steering angle sensor and cleared the EPS code which worked....
This morning (Friday), the garage tested the car and it was fine... until they tested it again at 12pm when the light came back on.
I picked the car up and drove it back to the office. About 4kms down the road the EPS started to work. I've parked it at work and will head home in 2 hours time.
I will check it again.
I'm thinking the motor is getting power to the unit randomly. Unsure if it's an electrical thing of the unit itself.
Someone in the UK has offered to sell an extra one they have.
Here in Australia, these cars are quite rare and very few in the auto wreckers.
Any advice would be great.
Cheers,

Your best bet is to see how it goes, from what I’ve researched and been told about the EPS is it will stop communicating with any scan tool you use to read the fault codes. If yours is still communicating and giving a fault code then see if you can find out what the fault code is exactly for and go from there.
There is a torque sensor in the Column separate from the EPS motor but is part of the EPS system so might be the issue. There is also a sensor under the passenger seat which I believe is a YAW sensor and interacts with the EPS as well.
I downloaded bmw INPA software to my laptop and bought a cable to go with it which really helped because the generic bmw code reader I got on Amazon was giving false readings and leading me to believe the SAS sensor was faulty when in fact my issue seems to be the EPS module which I have sent for testing and repairs and I am waiting to hear the news.
My car gave no faults codes whatsoever about the EPS, SAS or anything else. Just the yellow steering light on the dash and no power steering at all.
If it is the EPS which to be honest I think it probably is then have a google for a company in your country who will test and rebuild it as this way the fault will never come back or it’s a lot less likely to come back. If you get a second hand unit that hasn’t been rebuilt then you will probably have this issue again.
I am just giving suggestions and I am by no means an expert at all on this subject.
I've managed to get my steering column outing detach the motor and send it off to ECU Testing.
Courier companies are expensive and painful. I'm really hoping it arrives by close of business Monday and there aren't any holdups.
It is what it is I guess at the end of day.

Nice job! Lock the steering column with the steering lock if you haven’t already and leave it alone as if you turn the wheel too far left or right you can damage the torque sensor wires in the column.
Mines in for repair the last update I got was to tell be they are working on it so fingers crossed tomorrow it will be ready to be sent back to me or by the end of the week.
Hope yours gets turned around quickly! They charge £16.50 in the uk for shipping. I dread to think what it’s costing you to send it.

It cost me $250aud (145 pounds)
Thanks for the tip. The column is sitting in the boot. I'm not planning on touching the car until it returns. I'll lock it up though.
Yeah I realised that after I got it out. Ha ha. All good.
It’ll allow me a chance to tidy things up under the dash. Bummed I broke the clutch spring holder.
Worse things in life to worry about.
