Clicking Noise From Steering Wheel On Renault Megane When Turning Both Ways, Getting Worse, What Is It And How Much To Fix?

I have the same problem, and have been advised that it's the clockspring in the steering switchpack module. The clockspring is an electrical connector tape that feeds to the airbag, hence why your airbag light is probably on too.

There's some good info here: www.renaultforums.co.uk
