Hi guys, as the title says, I’ve got a HORRIBLE squeak coming from the front left wheel when driving around 30mph.
Been to the dealers 3 times and they said they can’t find anything, but for peace of mind they’ve replaced my wheel bearing (there was a hum too but they fixed that) and they also lubricated the diff but still no fix.
The sound DOES stop when I put my foot on the brake so my best guess would be that it is something to do with the disc. Won’t be the pads as the issue was happening with the original OEM pads as well as these brembo ones after I changed them. Anyone got any ideas?
Here are a couple videos https://drive.google.com/drive/folders/1-03QaVwfZ9TchivVTu92eWWjaF0_jpLO
thanks in advance!

Hi,
Made an account just to post this and say that I've the same thing on the Mk7 PP. Sounds like it's coming from the front right and seems to be triggered by turning left!
Looking forward to other people's experience with this.

Have you tried adding a bit of lubricant to the anti-roll bar? I used to have an awful squeak from the ARB bushes.
-
Concerning because:
A. The dealer “can’t” find the cause.
and
B. They are prepared to release the car with an unknown fault, possibly in the front suspension, steering or brakes.
I’d take the car, and your story, to another dealer.
My theory on the cause would be a stone between the brake disc and the shield.

I have had a similar on a track car where you have a buid up of brake pad dust hardened between disc & pad,,,, It goes when brake applied as you suggest. It sounds exactly like the noise in your vodeo!
This is not a worn out is disc or pad just a slight accumulation of deposit.
To resolve, remove pads and rub glazed coating or any rough spots at edges on a pice of emery paper on a flat surface.
Remove the shine on the disc with fine emery paper by hand, it's not aggresive!
It may not be this, (diagnosis on the internet!!?!) but doesn't cost much to do, just 20 mins and a piece of emery paper.

Appreciate the reply willni, will have a look into this I think it might’ve been done by the dealers though.

Thanks for this! Unfortunately gave it a go the other day but had no change at all :undecided: didn’t hurt to try though!

Yeah I thought it’d be a stone too. I asked dealers to look who said they couldn’t find anything but it’s on the to do list for next week as I can’t be sure that they even bothered to look :rolleyes:

Do let me know if you find out what’s causing the issue on yours too!

You say you gave it a go cleaning up the disc and pad, yet the dealer is looking for a stone caught between the brake shield?
You would have to remove the brake shield to access enough of the inner side of the brake disc to use an abrasive on the surface?
Just spinning the disc with pads removed would have discovered any trapped stones?
It will take some degree of disassembly.
Good luck!

I can't really hear anything from the video tbh, is the sound continuous? I had an intermittent squeak on my Clubsport S also from the front left particularly when going over bumps, anywhere the strut compresses basically and that was caused by the strut top mount bushes. An easy way to tell if it's a bush is by driving in the rain, bushing noises tend to go away when driving in the rain or you can spray some lubricant around them too.
-
Update:
Gave it a go today, disassembled it and removed the disk from the dust shield. there didn’t appear to be anything stuck there. Cleaned up any areas that had a build up of dirt with a wire brush before putting it back on.
The sound still remains :sad:
No idea what else it could be. A few of you have suggested bushes, but would it be characteristic of the sound to stop when applying the brake if bushes are causing the issue?

With different road surfaces a bush wouldn't be surprising, crawl underneath and just spray a little lubricant onto the two front bushes and see if it helps, I'm hesitant to say WD-40 as it's against rubber hopefully someone else could chime in on that front.
Otherwise could it be a belt in the engine bay? Open the bonnet and get someone to give it a little RPM see if it comes in.

If applying the brake stops the noise then no but is it the braking that's stopping it or the slowing down? sometimes bushes only make noise when under load shall we say, obviously the faster you go the more bumps etc the suspension is dealing with and then the bushes might start to squeak. It's not the wheel bearing as that's been replaced, if you've replaced the pads have they had enough time to bed in, new pads can be squeaky until they're run in, if they haven't been replaced then badly worn pads also squeak. If it's non of those is it possible that you have a warped disc? That can also cause squeaking, is the squeaking constant?

Thought it could be a warped disk, but would I not experience shaking/vibrating when braking? I am not experiencing that.
It’s definitely the braking that is causing the noise to stop, not the slowing down.

I think I forgot to mention but the issue only happens at around 30ish mph as you can see in the video

I'm definitely no expert, and your right about the vibrating, my Mini had a warped disc and had an awful vibration from the wheel and a juddering noise when braking however my thinking would be it depends on how warped the disc actually is, I can hear the squeak in that video and it does seem to be braking related. If it ain't the pads then there isn't really a lot else going on other than the disc, never had to change a disc on a golf so I have no idea what the setup is on a golf but I know on my mini even some dirt between the hub and disc or over torqued bolts when mounting is enough to cause issues. Maybe jack up the car and try rotating the hub to see if you notice any friction, in my case the warped disc wasn't free running and made contact with the pad for a quarter of a turn unlike the other side which was free running.
When I had the disc off and placed it on a smooth surface then it was extremely obvious as the disc wouldn't sit flat and rocked about, turned out to be a good thing in my case as I upgraded to vented grooved discs and ebc greenstuff pads which actually make the car want to stop now instead of feeling like the engine is doing all the braking. :grin: and for some context I'm 25 and have never drive a car older than 2010, so a classic mini felt completely hopeless on the brakes to me haha
Hope you get sorted soon zainahmed48, they say a unclean discs and pads can also cause squeaking but if you've cleaned them also to me it's probably not something that's going to cause any real issues but I know if it were me I couldn't leave it alone either as my ocd wouldn't allow it lol

You would definitely feel a warped disc through the brake pedal and the steering wheel, if you were exiting the carrigeway up a slip road from 70mph for example.
That sounds to me as if the brake dust shield/back plate is making contact with the disc, easily knocked and bent when removing the wheel.

Think the dealer checked the shield and found nothing wrong with that either, maybe it's time to find another garage to look at it?

Describes it perfectly :grin: :grin: :grin:

Yes booked in with a different dealer for Wednesday so fingers crossed !!

Mine has gone away all by itself for now.
I did prod the dust shields with a key, got some loud bongs but wouldn't pin this as the solution as it continued to make the noise for a while longer.
On a different note, I've been on a mission to eradicate rattles in the car and tonight gents, I've reached nirvana.
The last rattle was resolved by pulling down a bit on the foam that goes around the passenger feet vents. It produced a faint but annoying rustling sound over rough asphalt as when seated properly it's not secure enough.
Could have sworn it was coming from the back...

Update:
Been to a different VW dealer and the sound still remains. They’ve lubricated all the suspension bushes and also reported that the front n/s flexi hose is twisted.
Perhaps that is my issue and it’s not creating enough pressure to retract the piston fully??? Or could be slide pins which I haven’t looked at so might lubricate those while I’m at it.
They said it’s £75 just to straighten it :grin: robbery.
I’ll straighten it and update you all. Thanks for the help so far!

UPDATE:
Seems like I fixed the squeak!
It wasn’t the front left - it was actually the rear. The pads still have some wear left on them so that wasn’t the issue, instead it was the calliper piston not retracting fully. I cleaned up the calliper and relubricated the piston, and then reinserted it and bled the system. It seems to be retracting properly now.
I’ve driven it about today and there seems so be no squeaking at all, thank god!
Glad I solved it and managed to learn a few things along the way too.
