I've started noticing a light knocking/clunk noise. Initially on left and right slow tight turns, but now noticing it at light slow speed breaking. You can hear when mot moving and turning the wheels left and right. So It's not going to be CV joins.
Whats worth checking, Subframe, Control arm bushes, ARB Bushes, Engine mounts, Top Mounts?

Hi Neil I have pretty much the same problem, mine feels like something is bent, I have taken to the garage but they could not find anything wrong but there definitely a problem. I initially felt the problem more noticeably in the area under the foot pedals which usually occurred whilst reversing.
I have hit a few pot holes over the last few months, so I'm gonna try a wheel alignment in the first instance to see if that make any difference, although I am not convinced it will.

Sounds like the infamous subframe movement to me. I had exactly that on mine. It used to clunk on the brakes turning into my road slowly every time, and also on slower movements with a lot of steering angle.
The fix? - TyrolSport deadset. It's never done it since. Another thing the subframe movement used to cause was inconsistent handling when driving fairly hard.
The deadset kit is quite expensive, but you will see why when you get it in your hands. Fit and forget. It's DIYable as well if you don't mind clambering around under the car.

Thanks guys.
I don't mind spending the money if it fixes the problem. I guess its hard to prove that that is the issue though.
I might try these first as a cheaper optionto see if it solves the issue https://www.awesomegti.com/shop-by-brand/ecs-tuning/subframe-spacer-plates-kit-mk5-mk6-etc/

You could try taking it to garage that has shaker plates on their ramps, such as Kwik Fit. They then operate the shaker while they (and hopefully also you) can look to see what's going on under the car when it's being shaken.
-
If they are the bigger diameter Audi bolts, it might work. A lot of people report the problem comes back with that setup.
You need to take the bolts out of the subframes to understand why this problem happens in the first place, and deadset inserts is the only permanent fix.

Yeh, My thinking is, pay £16 and confirm if that's whats causing it, then buy deadset kit, if and when it comes back.

After having read this thread I think I have the same issue...
A light knock on braking, just the one. I get another one sometimes when I pull away again...
Lowish to Low speed, high steering lock manoeuvres cause knocks too...
Sound right...?
It's been doing this a while and garages haven't found anything. Having left this, is it likely to be causing further damage?
I see two tyrolsport kits... one is $90 and the other is the whole rigid kit at $285... I'm assuming it's the expensive one that is needed then?

The cheaper is for the rear. You need more the front kit, which has more parts and it's more expensive.

Personally I would just stump up for the TyrolSport kit and and never have to touch it again. I think there a couple of cheaper alternatives using the same method, but don't know how good/bad they are. The TS kit 100% solves it.

That could just be pad knock? Quite common on sliding caliper brakes.

Pudding..Re: moving pads...the garage mentioned this but said brakes were fine... how do the knocks differ?
Found a UK site
Forgive my ignorance.... you have a front and rear subframe...? So the first kit is the cheaper, rear, one - but both claim to fix the knocking/shuffling of the subframe. The second, 2.5x price kit also claims to have performance benefits too.
How do you know which subframe is causing issues..?
What kind of cost would you be looking at for a garage to fit these kits? Or just repalce with the larger audi bolts mentioned above?

Pad knock is more of a 'click' when touch the brakes gently. Usually does it once in reverse, then once again when braking forwards and that tends to be it for the journey because the pads heat up and expand slightly.
The subframe knock is a deeper clunk from the bowels of the car and usually during heavy steering at slower speeds.
I only have the front TyrolSport kit on mine, the expensive one. I can't say I've noticed any rear subframe movement, but I may fit the rear kit as a matter of course next time the rear end needs some work.
-
It's definitely more of a knock and it will do it over and over again, and I do get it with the heavy steering too. :(
-
I also have similar with mine. A knock on full lock left and slight knocking noise when centering steering - coupled with occasional hard steering and sloppy handling. Wonder if this would be the culprit/fix :thinking:
-
I've ordered the ECS bolt kit so will let you know how it goes. Also chucked an ARP panel filter in the basket as well :grin:
They have an install video, looks pretty easy
They switch between Newton meters and ft/lbs so watch out for that!
Heres a vid on the TyrolSport Kit
-
The more I listen to this the more I think its the top mounts.
I'll put the sub frame kit in and see anyway as it won't cause any harm. I'll then change the top mounts when I get round to installing my B8 shocks
-
You’ll be wanting TT top mounts with B8s, otherwise you will get rubbery squelching noises over speed humps etc with GTI mounts.
-
Thanks for the tip, I'll make sure I do that.

These ones?

Yeah they are probably the ones, but I used dealer parts. I've used Febi mounts in the past and wasn't overly impressed.

1K0412249B - Bearing x 2
10127707 - Bolt x 6

Febi bushes aren't good. I'd stick with OEM or Lemforder.

Cool, Cheers guys

Put the ECS kit in today. The noise is still there. Interestingly I already had the bigger bolts in subframe, not like the skinny ones in the video. The ECS were slightly different again as the had the captive washer on them, and slightly longer.
-
Same issue on mine, light clicking noise when going lock to lock going into/out of parking spaces etc, mine had the larger bolts in subframe, where a bit slack.
I'm thinking top mounts or ARB links binding?
-
Just to add a little more options to this... I have been having slowly increasing amount of noise like a clunk when going over small potholes and rough surfaces on the drivers side (RH) and at relatively slow speeds. Been looking for a culprit for about 6 months... everyone who looked couldn't see anything including the guys at AKS. I have changed suspension and top mounts and it was still there. Checked all other related bushes, nothing. The calipers have all been checked and disks are pretty recent.
Finally after another visit to AKS for some other stuff they diagnosed a worn steering rack and there was some slight play on the end float but very small. All the potential culprits like ARB bushes, Sub frame, Ball joints etc. were still ok. The play is very small but you can tell by pulling and pushing hard on the tie rods. We are only talking mm's here.
So in my case its a recon steering rack, Gen3 with new wiring loom :driver:
Cheers

How much do AKS charge for that? A worn rack will hit us all eventually! Symptoms are usually knocks over bumps and the car wanders easily in a straight line, needs regular correction.
I remember the GTI’s steering feeling tight as a drum in a straight line when I test drove one back in 2006. They definitely get vague with age, but people ignore racks unless they can see massive play, which is rarely the case. It’s always the tiniest bit of slack in the pinion/rack, which is amplified by the steering wheel diameter.
The UJ that connects the rack to the column is another favourite, but no one ever checks that.

Its the best part of 800+ to source a reliable recon Gen3 rack, with new wiring loom, genuine rubbers etc. and to fit. I think its usually the last step anyone wants to go down after replacing everything else. Alex was really helpful and we talked over lots of options but this is it. The problem is that the movement is hard to detect and I know it has been getting worse over the last 6 months. I could live with the noise for longer but I am past that level of tolerance now. The main pluses are getting a trusted source, fitted by experts and with some guarantee. No its not cheap but I am keeping the car for a while.
To be fair as well the car doesn't really show other steering symptoms so it wasn't an obvious candidate and the steering still feels tight. I also didn't feel any knocks through the steering wheel which I might have expected.

Hi got my Eddie booked in at AKS in June for an inspection as still experiencing the clunking noise and possibly suspect is the rack worst case scenario looking at 1100 ish to supply and fit, hoping it’s something else ie something cheaper
