fuzzy14

Hi all, I do apologise for any inconvenience this may cause, but I bought my first citroen c3 in January 14, car was great with no faults. Car is a 2003 1.4hdi. 1 morning I started the car and the steering wheel turn full lock right itself, tried the ignition trick with no luck? Been too garage no faults? Then it got worse (kind of) total failure on the steering and is really stiff now. I dont want to sell the car as really like it but can no longer afford the garage bills :'(. The local breakers has one and guy said it had no faults. I have already tried changing the ecu behind the battery with no difference to the steering, speedo still works at all times?? Please anyone any help, advice would be greatfully appreciated thanks
