About 1k miles ago (currently have about 20k on '11 S4), I started hearing clunks/knocks from the front suspension when braking and/or turning at a very low (5-10 mph) speed, such as turning into gas station. The noise is very noticeable and I'm a bit concerned about safety. Planning on taking it to the dealer, but interested to see if perhaps anyone else is experiencing the noise.

Any mods? I was having similar sounds and it turned out to be my Alu Kreuz was not torqued correctly and was loose. Now it is rock solid again.

no mods, it's 100% stock

Have the same issue with my A5. Tried to have it fixed for months and gave up. Only happens as you described and when the car is hot during the summer. If you can reproduce it on command drive with a service tech. Love to know what the actual issue is.

Koobah, have a look here: https://www.audiworld.com/forums/sho...7#post24312577

Could be the same issue on these '11 cars...

I have the exact same problem on mine as well. On my past cars it always seemed to be a tie-rod end or something like that. My car only has 9300 miles. I am in Central Texas so the heat makes sense. Always notice it on low speed turns. Will definitely let you guys know once I get time to make it to the dealer.

A strut problem..yep that could be it for sure. Damn.

****, that does not sound exciting at all.

Mine did it stock and then after I installed H&Rs so I'm 100% sure it is not strut related(top mount portion anyway). I checked all the linkage bolts both compressed and uncompressed(lift), dealer checked it and it remains but only in warmer weather, maybe 60deg F and above. I think its something in the sway bar/links but wasn't willing to spend money chasing a ghost that Audi denies exists. I plan on continuing the chase with the new owner if he gets the urge... he's a home mechanic type too and noticed it right away. There is a design or manufacturing fault there somewhere.

Mine does it too.

Here are the conditions in which it is very prominent:

-Hot weather
-Car driven more than 15 min
-Low speeds
-Amplified when hitting bump under braking

Car is 2011 S4 with 13,500 miles.

It is a horrible sound, and I hope Audi can replicate it. Most likely they won't, because all of the above conditions have to exist for the sound to be really noticed.

I have read something on a different regarding sway bar end links not being tight. Not sure.
