992 strange rattle/creak from the dash when cold
Discussion
Hi all,
I’ve had my 992 C4S Coupe for just over a month now and absolutely loving it! – I’ve covered just over 2600 miles so far including a fantastic 1700 miles road trip through Yorkshire, Pennines, SWC300 and over to the IOM + I also use it as my DD.
One thing I started noticing on the road trip (which has got worse since) is a rattle/creak (the kind of sound a poor fitting bit of trim makes as the car flexes over bumps) coming from the dash area around the PCM or Sports Chrono clock / dash top vents, particularly if the road is a little bumpy. I’ve pushed and prodded the plastic vent trim around the SC clock but it doesn’t appear to be that. I had originally incorrectly put the sound down to my windscreen mounted speed camera detector flexing on its mount but have since removed it and the sound remains.
The strange thing is that once the car is warm after about 15-20 mins of driving, it almost completely disappears, even over very bumpy roads.
Anybody else experienced this? – I’m thinking it has to be related to a ventilation component/trim contracting in this cold weather overnight (though my car is garaged) and causing the rattle/creak for the first 15-20 mins until it warms up and expands?
Other than that she’s absolutely fantastic!
Cheers,
Joe

During this morning’s drive to work I finally managed to track down the annoying squeaking/creaking that’s been driving me crazy…. It’s coming from the air vents in the lower dash / center console. If you jam your fingers/mobile phone in the 10mm (ish) gap between the ventilation controls in the lower center console and the air vents it completely stops even over very bumpy roads. I’ve jammed a microfiber cloth in there as a temporary fix.
As I say the really strange thing is that once the car is warm after about 15-20 mins of driving, it almost completely disappears anyway, even over very bumpy roads.

To be fair, I'm pretty much rattle free, get the odd squeak from the fire extingusher that appears to be tie wrapped to the passenger seat, but it looks cool so I forgive it.
Still got to get my pre-tensioner sorted, mine doesnt give the little seatbelt tug when you first pull away. Someone on here said it was a setting in the config somewhere, but damned if I can find it. Trip to an OPC in the spring to sort it, just CBA until then. Someone will probably now say its dangerous.
Mines in hibernation anyway for winter now, in the far south west, away from the salty midlands roads. Heading down there between Xmas and New Year, hoping for some winter sunshine and the Lands End loop, maybe a blast down to the Lizard too. Roads are great down there when its quiet.

Great to hear all is going well with yours… seatbelt pre-tensioner aside (now you mention it I think that that does ring a bell as a setting deep within one of the menus).Still got to get my pre-tensioner sorted, mine doesnt give the little seatbelt tug when you first pull away.

I've covered 3000 miles in my C4S now and she was very much purchased to include daily driver/commuting duties… winter included… (I’ve got a 718 Spyder arriving in March for high days, holidays and track days), that said the C4S was treated to full PPF and ceramic + garaged at both home and work.
Aside from that small creaking vent issue, I am so pleased with her… In summary I think I’m most impressed by the sheer breadth of/all round ability…. Driving home tired after work on a cold wet winter night or long motorway journey, she performs the luxury grand tourer/coupe role adequately, yet is no harder to live with than a Golf…. On the flip side, flick it into Sports Plus and hit 140mph+ over the mountain on the IOM TT road and she performs equally/admirably well as a focused sports car for committed driving.
All the best,
Joe
