Can I jump on this thread too? I have a Corsa B system on my Escort. It has started to pull to one side whilst driving. All the suspension geometry has been checked and is correct. I had the car on the lift recently and when I started the engine the wheel automatically turned to the left. Can this be adjusted out using the torque adjuster mentioned previously or is thee another issue? Cheers Phil

Sounds like the torque sensor has failed (they do, I gather).

Are the Corsa/ Agila etc. epas columns identical for LHD and RHD cars?

The torque sensor won't have failed, it's just out of calibration and needs adjusting. I'll do a how-to later when i'm not on my phone.
The Corsa B columns are different LHD to RHD I've not seen a LHD C so not sure about them.

Corsa C columns are different between left hand & right hand drive, you also get fixed and tilting versions, if you hunt you can also get a heavy duty version that was specified for driving school cars

Hi Mantasport,
Do you still have this blue plug with wire? I need 1 for my EPS. Also, do you kmow what amp rating fuse I should use?
Please let me know in pm.
Cheers Atchi

Got it and fitted! Is it very quiet? Not sure if it is actually working but time will tell when i take my car out of my garage to turn it around. With a LSD, it was very heavy in slow speed.
Cheers Atchi

You need resistance against the wheels to feel the assistance, so if they are in the air you can't really tell. As to how much you can feel at that point a lot of it is down to the speed controller you are using. Some are a linier type which just set the assistance level from the dial position, which can feel too light and numb. The better ones take the dial position and also use the columns torque sensor to adjust the assistance level in response to the load on the column.

Hi sorry to dug up an old post ! But I retro fitted a corsa B ( I think it was a B,!) Unit to my 58 100e last year. All seems to work fine. But I've started to notice that after driving for a while, it seems to "lock up"! Meaning not only does the wheel go heavy, but it take a bit of pressure to get it to turn ! Once turned a little in either direction, assistance comes back and steering goes light again.?? Just to add I leave the VR in the fully assitanced position as it seems fare nicer to drive like that. Steering is really hard if left in the unassisted position.!!

I've had a similar issue with mine. Not whilst driving, but for some reason every time I go racing. It works fine putting the car in the trailer, fine going through scrutineering, fine as I go round the sighting lap. But when I go to start it to do the first stage it doesn't work. The steering wheel twitches as I turn the ignition on but that's it, no assistance. If I switch the kill switch off and retry, after a few times it works faultlessly. Until the next race meet😩. I'd love to know the cause.

Once turned a little in either direction, assistance comes back and steering goes light again.?? Just to add I leave the VR in the fully assitanced position as it seems fare nicer to drive like that. Steering is really hard if left in the unassisted position.!! Not one i've come across before. There is not much mechanical inside the column that can go wrong but free itself off time and time again. A failure would remain a failure i would think, there are only a couple of bearings and then the worm drive and gear on the main shaft. If you can get it to go all stiff i would try unbolting the motor from the side (2 10mm headed bolts) and see if it stays stiff. If it does its mechanical because none of the electric parts would have any influence at that point. It could be an ecu issue as the B ecu's were not as good as the later C's. Or possibly a speed controller issue, because you should not need full assistance to make the steering feel ok. On the controllers i've always used full assistance isn't even needed on a quickrack equipped manta 400 rep with 8"wide slicks up front. If the controller or ecu are trying to feed the motor both ways at the same time i could see it locking up. The one other thing i would suggest is look at the rest of the steering setup too. Either the U/J's or the rack (or box) could actually be the parts seizing up. Plus if they were overly stiff all the time that would explain the need for full assistance normally. Oh and a B column is easy to spot as the ECU is a large rectangular shape with the 4 input plugs on the top of one end. The C is square and 2 inputs on 2 opposite sides. I've had a similar issue with mine. Not whilst driving, but for some reason every time I go racing. It works fine putting the car in the trailer, fine going through scrutineering, fine as I go round the sighting lap. But when I go to start it to do the first stage it doesn't work. The steering wheel twitches as I turn the ignition on but that's it, no assistance. If I switch the kill switch off and retry, after a few times it works faultlessly. Until the next race meet😩. I'd love to know the cause. That sounds like an issue with the speed controller or possibly the ECU. Some of the speed controllers are just not as good or reliable as others. If they see a voltage drop they can just drop out and will not restart even if the volts pick back up. they need the ignition feed turned off and the back on again to reset. I had this with one of the first types i tried, it dropped out if the voltage dropped bellow 10v, and starting the 6cyl engine in the manta always dropped it bellow that point. I did a temp work around with a switch in the ignition feed to the controller. Start the car with the switch off, then flick on once the voltage is back up and it would stay working. But i found a different make of controller and installed that as a proper fix, which is the same type i am using now and have over 100 of them without fault or issue now.

Surely the cause is Vauxhall parts on a Ford Yeah they are probably shocked by the reliable parts (which are actually made by NSK and Mitsubishi) as being a Ford they don't expect that.....

Thanks for the reply Mantasport. I'll give that work around a try to see if it cures it. What make is the speed controller you use?

Thanks for the replie. I wonder then if it might be an issue with the variable speed controller?? trying to power the unit both ways ?? As when driving in a straight line, it does seem to want to " twitch" left and right a little bit ?!! I just put this down to the tracking possible being out and it just trying to correct itself all the time ?!

Its going to be a case of changing one and seeing if it fixes it, then if not changing the other i'm afraid. You might be able to borrow an ecu off someone just to try, as its a simple plug in thing and easy to test.

A d ironically it seemed to be working fine again. ?!! So its definitely baffling!!

Seems to be a lot of steering column knowledge on this thread So I'll chip in with my question if I may...... Can any of these powered columns be converted to take a 24V motor I want to put a powered column in my old LandCruiser, but it is 100% 24V, and getting ~30A of 12V to run the column isn't easy or cheap. Getting a smaller 12V supply for the ECU and gubbins wouldn't be an issue but 30A for the motor is. Thanks

A large capacitor (maybe a Farad or two) might solve that, if that isn't enough, a small 12v batt charged by a dc-dc from the 24v system.
