The car its self feels a bit lighter in turning, ive also tried turning the wheel left and right while stood still and it still does it.

Hi..there thanks for your responce.. you know the car uses an electronic steering assisted system which means the steering is controlled via an ecu behind the battery and torque sensor and steering motor located as part of the steering rack..faults on these arent too uncommon just so your aware and normally the ecu very rarely fails but more so the torque sensor itself which as highlighted is part of the steering rack which to rectify requires a new rack to be installed and then re-calibrated..

first checks to make are the connections at the steering ecu on the c3 it should be located directly behind the battery you see a 2 pin blue plug/a 2pin black plug/then a multi plug all of which are located ontop of the ecu..those need to be checked for security aswell as contamination ie: water certainly check those..the next check is the charging system/battery to make sure the battery isnt creating low voltage/voltage fluctuation problem or the alternator is faultering so certainly have that checked/tested out..aswell as the belt itself down at the side of the engine/drivers side to ensure that is slack or loose..the next stage unfortunatly with these after all thats check out is the diagnostic route car plugged inso to need to find machine/garage thats able to test or interogate the steering ecu and see if its actually stored any fault above that the best advice form here on this problem..i do hope this helps
