Audi S5 play in steering/knocking noise

[Steph Hanney]

Hi, need some advice/help. I own a 2008 Audi S5. Recently when turning slowly either going forward or reversing there feels like play through steering wheel and a sort of knocking noise.This only seems to happen at slow speeds, like turning or reversing into my drive for example. The car handles/ perfectly otherwise. I'm going to get booked in for a diagnostic, just curious to hear any members thoughts on what may be causing the issue.

cheers!

Getting it checked by a professional is definitely the best course of action you're taking. Is the steering electric or hydraulic? If it's the former then a failing battery could be causing an issue. Especially as the battery would have to work harder when moving the car at slower speeds when parking etc  And it's definitely worth getting the battery checked. I admit this doesn't explain the knocking noise. 

If it's hydraulic (most likely) then it could be a pump or pulley issue.
