992 Creaking noise in cabin

[Schuey]

Hi,

Hoping some of you can help. My car, a 992 GTS which I've had from new, now almost 9 months old has developed an intermittent creaking noise coming from the cabin. I only noticed it because whilst on a drive, my PCM decided to do a reboot and so the music went off and therefore was driving without any radio on. The creaking noise comes when the cars goes over uneven surfaces, bumpy roads and some speed humps. I was wondering if you’re aware of this on your cars and if so, have you had it resolved? It appears to be coming from the front behind the dash. I'm not sure if it's part of the trim that is flexing and therefore rubbing against something or indeed if it is suspension related. I found this thread below on Rennlist, the guy has posted a video and mine is making the exact noise as his car, so I'm hoping he can help as I posted a message to him (No reply yet).

I popped into my local OPC last week and Sod’s Law it didn’t make the noise when the technician went out with me. ??. He’s told me to make a video next time it happens. The car drives fine, handles great so nothing seems mechanically out of sync. However, would like to find out what it is because whilst on a drive yesterday it did it again. You can't hear it when the music is on, so it's quite faint, however it seems more prominent when the car is in 'Sport' mode as apposed to 'Normal' mode. Now to be honest, I don't know how long it has been going on for, because I always have the radio on. Like I said, I only noticed this because the PCM did a reboot and it went all quiet in the car, so I was able to zone into this noise.

Any help will be appreciated. Many thanks!

As a process of elimination, try moving things. Move the steering column, open the glove box and slam it shut, open the cup holders etc.

Sometimes noises that sound like they are coming from a certain spot are actually coming from somewhere completely different.

Culprit may be a seat since it disappears when occupied. Try repositioning each seat in turn. Set the passenger's side fully forward with the backrest pushed down, then try over a known section of road where the noise has occurred. ????

+1 on the above Jas.

With squeaks and rattles [known in vehicle refinement circles as SQR??], as Dan says I’m afraid that it’s very much a process of elimination. Sometimes it’s useful to have a passenger onboard who can listen for untoward sounds while you’re driving and "wiggle” things around.

Unfortunately, it’s impossible to "unhear” sounds once you’re aware of them!??

Thank you gents, I will try these methods and see how things go over the next few days. Appreciate your replies. []

Run - cycle the A/C system through all of it`s modes - settings, it may be a sticking - loose `flap - actuator` ?

Have you checked the scuttle section, under the bonnet for anything loose - rubbing ?

I did check the scuttle section and all seemed ok there, Andrew. I'll run the A/C system through the different modes this evening along with some of the other checks as above. Willing to give anything a go.

Having looked online, it was surprising to see how many other people have some kind of buzzing, rattles, tinging, creaking noises on their 992s. Makes me feel I've actually been fairly lucky to this point. I just hope it's nothing serious like a suspension component. I haven't hit a pot hole or anything to have caused any damage, so in my head I'm thinking it can't be suspension. But then again, the GTS does come with the additional helper springs like the Turbo/S and GT3, so could it be that?

Sorry to hear this Schuey, hope you get it sorted...nothing worse than a noise appearing and no clue where its from...I blame VW and their advertising in the 80s.

I’ve had my GTS since the end of February and it had a slight creek from day one. I traced it to the passenger side door card armrest rubbing on the storage bin underneath - hope that makes sense!
it always disappeared when someone was sat in the passenger seat with their arm on the rest. I have now sorted it by wedging a Tesco club card fob (the small one) in between the 2 - the club card cannot be seen as it is inside the storage bin and it also would have looked daft if I’d wedged it in from the outside!

I'll look into this, thanks. And did you get the creak when you went over bumps and uneven road surfaces, or was it constantly there?

[Longp2]

Ignore the last post, not sure why I quoted everything!


The noise only occurred when the road surface was uneven!

 

[Wheelnuts]

Slight connection to Schueys noise problem, I have noticed what appears to be a slight rattle from the sport chrono clock on certain road surfaces but not constant. Has anyone noticed a similar issue?

 

[Laurence71]

My "2 cents” view is that there will be creaks and rattles in most cases. I had my 992 for 3 years and 22,000 miles and other than some serious rattles (broken bits replaced under warranty) there were the general creaks and rattles you would get on UK roads.


I tend to put this down to the numerous materials used, even the weather.


It is annoying, not just because it’s an expensive car, but you can’t ignore it.

I hope you get it sorted.

Hi

My 18way driver‘s seat creaked from new, initially only in my chosen position. After a few hundred miles I have found a sweet spot and there is no longer a creak.


Might be worth trying a different seat position if you can find one that works.


The diff between a creak and not was a very small adjustment.

I've had 3 992's now and all had creaking drivers seat. Adjustment of the position sorted it but every one creaked in the same place/way. I drove another 992 at the PEC and that had the same issue. (maybe I just need to loose weight!)

2 of the 3 had rattling door cards, and although bits and pieces were replaced they all still rattled in one way or another. One had a loud rattle from the Sports Chrono, and this was replaced under warranty and solved that, and all of them had/have creaks around the dash.

I agree the stiff suspension and UK roads doesn't help, but also not sure the build quality at times has been as good as expected.

Also all 3 of my 992's have had a rear light replaced due to condensation, so maybe another known issue. Interestingly my current GT3 has less rattles than my previous 992's although I expected more given the stiffness of it and reduction in sound proofing

 

[Schuey]

Thank you all for your feedback and responses, all helpful and informative and puts my mind at ease that it's all fairly normal with these cars. Creaks are obviously a 'characteristic' of the 992s! ??

I went out for a drive last night and I didn't hear the creak at all, so I think it must be temp and road surface dependant. I won't worry about it and will just enjoy the car.

If it comes back and I do narrow it down, I will update you on what it was so it can help others.

+1 on the rear light condensation - driver side only, but booked in for a replacement. I took delivery in Nov and have noticed a variety of rattles - all of which I can live with (or drown out) bar one. Originally thought it was located within the passenger side headlining, but now certain it’s around the sunroof as it disappears when it’s tilted open. Hopefully an easy fix. Good job the weather‘s been so fine!

 

[Longp2]

Quick follow up offer for anyone interested, I have a "Rattle finder” MP3 sound file if anyone still has any annoying noises in the cabin that they would rather sort themselves rather than have the dealer pull their car to bits!
I used it yesterday and managed to pinpoint a couple of annoying rattles which I will sort out once I get back from my jollies!
If interested just PM me with your email address and I’ll send them to you.

I traced a seat creak to the seatbelt mounting / buckle between the seat and centre console. It only did it when warm and with me (large) in the seat. A strategically placed microfibre cloth stopped it.
