Whatever pictures of the part your talking about?

02-16-201702:twoscore PM

Cross brace makes me think of the part that would be replaced past the Alu Kreuz (one time information technology finally ships).

02-16-201703:01 PM

Sounds like the little brace under the cowl? Very interested every bit I have the same sound. I thought information technology was the command arm.

02-xvi-201703:03 PM

Pics and location details please. Thank you.

Edit made- picture inserted on original mail service. Promise that helps.

Were the bolts not torqued to spec from factory? Or did they loosen over time?

I recently read a APR 4.0L down pipe install procedure that covered the removal and install of that role. I have the 3.0L and will never install downwardly pipes just I thought it was interesting since information technology showed step by step instructions getting to that brace.

02-xvi-201704:43 PM

Apparently the brace tin can loosen. If it does and you become the "clunk" then y'all accept to loosen all bolts and retighten. The APR instructions mentioned higher up are probably very helpful.

Reply back if this fix works for you. Information technology would be overnice to resolve this once and for all. Is information technology the same effect for everyone or can it exist caused past multiple bug?

Cheers for the info. Very helpful.
Audi's official maintenance documentation term for that is the "Belfry Brace".
There are 5 Bolts... torque specs are 20 Nm.

02-16-201710:08 PM

Only tried this. Backed out of the driveway and did a hot lap. Then far so skillful. The true test will be in the morning, as that'south when I normally hear the clunk the most. I'll report back in a few days to make sure it'south non a placebo.

I tried this every bit well since information technology was like shooting fish in a barrel enough. BTW none of my bolts were loose. I recall, as has been discussed, in that location are a couple of noise related issues at hand. The louder clunk, almost like a CV joint clunk, described hither may be addressed by this prepare, only the fainter rattle while going over bumps at low speed might still be lower ball joints as discovered in other threads since I nonetheless hear the faint depression speed rattle coming from the front suspension. I'yard sure I'll get it checked out ane of these days.

02-21-201711:33 AM

Gave it a shot this weekend and the knocking dissonance is gone. My bolts weren't excessively loose, merely however even so needed some tightening to spec. Thanks OP.....saved a second trip to the dealer.

03-10-201707:53 PM

I had this and was meaning to have it in. And then today I didn't see a speed hump and slammed on brakes and went over information technology faster than I wanted. Noise got louder. I figured it was this and the shop tightened it and racket has so far decreased. Shop said it was loose. Must exist common issue.

Which vendor volition be commencement to come up with the bigger/stronger strut tower brace for the C7?

03-xi-201705:00 AM

Mine was simply in for service and I couldn't call up the fix...I told them control arms. ARGH! At least I can do it myself in ten min.

03-11-201701:47 PM

I can confirm that this solved my problem. collection a lot more today. clunk from out of driveway and over other uneven surfaces gone.

For myself, unremarkably I had a dissonance when turning more sharply and slowly over an uneven surface (driveway, dip in road etc). Dissonance gone now.

03-eleven-201702:xvi PM

I tried the strut brace set and it didn't help. Simply...I ended up finding a fix for my "clunk!"

I was digging through the cowl on the drivers side, and noticed I could replicate the noise by borer on the black windshield washer reservoir. Information technology turns out, the top portion of the reservoir would tap on the ecu. I added some sticky dorsum felt to the lesser of the reservoir and GONE. So fuckin happy now

Establish this thread every bit I have been experiencing this clunking phenomenon lately from about the engine bay during low speed maneuvers that may involve twisting the chassis in my A7. Opened it up and started torquing those bolts to spec. To my surprise, all of them required 1/8 plough or a petty more to be tightened to spec. I believe the center bolt required the most turning to spec. Hopefully this solves my trouble.

06-18-201706:46 PM

Going to try this on my 13'! I just picked the motorcar upwardly and all is well, except for the faint clunk in the forenoon bankroll out of my steep driveway. Excited if this is an easy fix.

Anyone got the original photograph? Or know tiptop of their caput what socket size to use? Wanna show it to my friend with a clunk...

Afterward installing the 034 density control arms, ALL sounds went abroad. All sqeaks, creaks, clunks. Highly recommended.

They are five separate 10mm triple square bolts property the strut brae in place. I'm sure it'south very common cognition to folks that work on German language cars, just I had no clue until recently and had an interesting time tracking down a triple-square gear up of sockets to be able to work on downpipes as well equally sway bars...

06-30-201708:35 PM

Simply had the dealer re-torque the "Tower Brace". I had a very bad "binding" awareness when turning at and past xc degrees. Asked the dealer to address this and he looked at me like I was crazy....said this shouldn't affect anything. After the service there was a noticeable difference! Binding macerated and the steering seems tighter and more responsive.
The service manager said the bolts were a little loose.

09-06-201706:00 PM

Lamentable to revive this, do the c7 A6's have these brace? I'k having the aforementioned issue right subsequently lowering my car (installed springs) and my mechanic couldn't locate the problem.

Thanks!

Yes. Simply open the hood and pop off the pelting guard the base of operations of the hood/dorsum of the engine bay. Yous'll run into a horizontal silver-colored caryatid that is held in identify by 5 triple-square bolts.

09-06-201706:twoscore PM

This was my consequence on my S6 likewise at1200 miles on the clock. The bolts were not torqued to spec on the aforementioned office as you. I had an additional issue with vibrations in the dash and steering wheel and the commodities in the engine mount was loose too.

12-02-201701:57 PM

This solved most of the clunk noises on my A7, post-suspension install. I still have a small 'click'when I turn my wheels merely I retrieve that is tie rod ends.
What I did was loosen all v bolts, and then Re-torque the ii at each stupor chapeau, then lastly the bolt at the firewall. I went with twoscore ftlbs of torque because 20 felt too calorie-free to me, fwiw.

Did you lot guys likewise have the clunk sound when braking hard, whether at high or low speed? I accept the clunk sound announced when reversing and turning the wheel, but as well when braking hard. Been to the dealer nearly 5 times, they tin can't fix it. Replaced struts, upper control arm, re-torqued entire interruption, then they gave up. I took it to another dealership, they said must be the lower control arm, take it dorsum to other dealership. They sort of suggested information technology may be the subframe. Information technology's a 2013 A7 prestige with 81k miles.

You accept no thought how many trips to the dealer information technology took without them figuring it out. In hind sight I got a motor mount and some worn bushings replaced. Frustrating for them to discover out this was such a simple fix. Sad I didn't discover this thread over a year ago.

This thread should be stickied.

08-04-201908:37 PM

Just wanted to add my two cents and get in possible for others to notice this solution. I had the aforementioned problem in my 2014 S6 but it seemed more than of a popping dissonance so my initial internet searches did not find this thread. I took it to Audi and they had the car for a week, thought they establish the problem (torn bushing) but it came back the next twenty-four hours. Later on discovering this thread, my son and I loosened and retorqued the strut bar bolts as described - problem solved. What a relief!

08-05-201909:ten AM

I have this noise again and need to retighten, but I did it years agone and forgot where to torque. Anyone have a picture again?

Hither you go (circled in red; not my moving-picture show)

Merely thinking, might be usefull to put some locktight on the bolts and torque them to specs...since it is a known result they tend to get loose over time (depending on driving style i guess :p ).

09-16-201912:53 PM

Sadly, this was non the source of my new, post-sway-bar front-terminate clunk.

02-02-202010:33 PM

This solved the clunk dissonance on my 2012 A7. The noise was progressively getting worse so glad it was such and easy ready. I could run across on the driver side where the brace had been sliding/shifting. Loosened all 5 bolts then torqued to spec and proficient every bit new. :)
