Powersteering light on dashboard shows red??? Vehicle turn extremely difficult
Does your car have electric or hydraulic power steering?
If hydraulic, have you checked the power steering fluid level?
Audi A3 2009 has electric power steering (I am owner of vw passat b6 2008 and it has electric power steering) , so it is the same in Audi also. It is time to replace it or repair. If you have VCDS diagnostic tool, your will see what error you have.
