Steering wheel knocking noise

[Embisix]

It was resolved in the end. The issue was the lower section of the steering column which was replaced.

Potential solution: I had similar problem, a mechanic checked bearings, suspension, drive shaft and balancing and could not find the cause. Then a random chat with an observer from the Institute of Advance motorists led me to the answer. He had a past vehicle where the problem came from a cracked wheel: which could only be checked when the tire was off. But it was some thing simpler.

When I had the two front tires replaced it turned out there was corrosion inside the wheel. This was cleaned up and the problem vanished.

Not sure how either issue would cause a knock through the steering column...

I have fixed the problem. Thanks to Embisix. The service has checked and cleaned the lower section of the steering column.

I'm getting issues too.

At low speeds and only when the car has been driven a while (i.e. up to full temp), I get a distinct knock/thud reverberating through the steering wheel rim and I can also feel it through my heels. This happens at anything below 20mph or so as the steering wheel passes through the 2 o'clock and 10 o'clock positions from centre.

The dull knock/thud sound is not loud, I can feel it more than I can hear it.

I'm waiting for my local dealer to call me back and have spoken to Audi UK. There are no TSB's or Recalls relating to this issue I'm told.

Any ideas what this could be? Anyone else experienced this and found the cause?

Mine's a 2010 MY and so has hydraulic PAS.

My wife has a 10 year old Honda Accord and we got the same issue with that, it turned out to be an engine mount.

Hi,

I will refresh this topic a little bit, is this an issue You were facing with (hit link to google drive)?
If yes, what was the reason? I've exchanged and cleanned power stering system oil to Febi 6162. It was okay for 2 months but now it appears again.
Any advices appreciated. Audi A6 C6 2007

Hi,

Over the past few weeks I have a knocking noise when turning the steering wheel at low speeds. Its a pretty noticeable noise that the passenger can hear too. I can also feel the knocking noise (and by feel, i mean it's like someone is tapping on the inside of your hands) while turning the wheel.

The local garage has checked the bushes and mechanical side of things and they think it could be the electronic power steering pump, but they don't have the kit to verify. It just started up out of nowhere, no collisions or anything.

Is the power steering pump a common failure on the b8? The car has only done 34k miles. Any ideas as to what else it could be, bearing in mind its not the bushes, springs e.t.c.. The steering itself feels fine.

Finally, can anyone recommend a local indie who could check the power steering pump in Manchester, who would also use genuine parts? Otherwise, a trip to Audi it is.

So... I know I created this thread a few years ago but the issue has finally been diagnosed as it became persistent enough. It's the steering column UJ joint which is apparently sticking and needs changing. That's what is causing the knocking noise apparently.

Hi,

Do You have old UJ joint picture? I'm happy to hear it's not steering rack
