anyone know why? When i turn the steering wheel, it seems to make a slight knocking noise. not sure what it could be, any help would be much appreciated.

It may have been a lubrication problem. My friend had a same situation with you. What he did,he look underneath the car. And found out his steering system is covered with dirt.

Or maybe you can take it to the authorized dealer,they likely have the answer.

I have that on my renault clio but i also have no idea what it could be. I have taken it to several garages and they also have no idea, it could just be one of them things.
