The S4 cars have a known issue and there is a TSB addressing it. I don't believe anyone has identified the issue in the A4 cars with the Sport suspension...

Note that if a tech only does a visual inspection and yanking, pulling or pressing of the engine, chassis and suspension components, it may not reveal that a bolt is not tightened to factory specification. That was what happened in my case until he put a torque wrench on all the bolts and found the one engine mount bolt that was not tightened to factory spec. Low speed clunking problem solved. No TSB, just careful, methodical checking for spec with the proper tool.

Do you know the TSB number that you say is addressing this issue? I brought my car once to Audi of Arlington about a month ago regarding this problem but they couldn't replicate this clunking sound.

Thanks,

Does anyone have any other link to Audi S4's TSB? This is what I found and it doesn't have the one that states the clunking noise that we hear in our cars.

See the attached image. I used to get this problem pulling into my alleyway. They replaced some guide links in the bushings and loosened, let the motor sit, and then re-torqued it in.

Thanks!

Thanks for posting this. For what year are these? I tried searching for these two that you provided under 2012 S4s and they're not included.

Thanks again.

Update - hawk sent me a new front pad and once installed the noise disappeared. Turns out the metal bracket on the pad itself was defective. It is supposed to have flex and move but on the bad part it was vibrating causing the noise. It's been a few months now and all is well. Good luck to the rest of you on finding a resolution.

I am having this exact same problem on my 2010 A4 Avant. Whenever the body weight of the car shifts front to back I hear the clunking in the right front of the car. Doesn't matter the temperature. It does it the most at low speeds and turning, as others have described.

Read my earlier posts and as I replied to you in the other thread. Check the torque of the engine mount bolts.

My 2011 S4 has recently developed a clunk as well. Seems to be coming from the drivers side although that's not clear. Does not seem to be temperature related - I get a clunk when engaging the clutch and the car starts moving and then a slightly different clunk when first hitting the brakes.

I checked the Alu Kreuz but all the bolts are tight - going to bring it into the dealership for a look. Unrelated but I noticed a bit of fluid on either side of the driveshaft tunnel (on the chassis). I wasn't sure but it looked like oil making me wonder if a seal is leaking, so now I have 2 reasons to have the dealer look at it. This will be the first time having it looked at while under the dealer sold Fidelity aftermarket warranty. Will post back next week once I get an updated.
