steering turning on its own

Hi,when my c3 is sitting still or when i take off the steering wheel turns right on its own,when im driving and take my hands off the wheel its ok itll keep going straight whether 30 or 70 MPH,ive had someone have a look at it and hes not sure whats causing the problem,he done a couple of ecu or bsi resets hoping that might fix it but no joy,when turning left ive gotta turn the wheel but when turning right it just flies around,ive included a short video,thanks in advance of help.
im sorry but when i try to upload the video it keeps saying no file chosen

I get the idea of what's happening, however if you want to post the video you could upload it to youtube and then place a link here? Remember to make the video public on youtube otherwise the link won't work.

Hi algdak

You will end up changing the power steering rack and the power steering ECU as these are the 2 things that cause the fault and it can be tricky to determine which one.

Doing just the EPAS ECU my work, but you may end up with 2 blown EPAS ECUs and be no better off.

Yes, you can't upload videos to the forum, only pictures. If you have a video it needs to go on youtube and use the 'youtube' BBCode.

Thanks for the replies and sorry for the delay,

If you want to try just the ECU first, then you can pick up an ECU here (ebay click) but be prepared to do the rack too from this link can be a cheaper option (click) than new.

If I get a second hand steering ecu are they specifically coded to each car or can i just buy any one and fit it to my own car. Or do I need to match the numbers on the steering ecu to my original ?

They are not coded and they are quite common across the various Citroen models. It would be a good idea to match the numbers if you can, failing that go for one from the same model and spec as yours.
