A clicking noise on full steering lock is almost always caused by a worn outer CV joint. It occurs when the balls inside the joint wear down and develop excessive play.
On the Renault Megane III Grandtour, you can often replace the outer CV joint separately. However, if the inner joint is also worn or the shaft has corrosion damage, it is usually more cost-effective and reliable to replace the complete drive shaft.
