There is a dashboard rattle that is driving me insane. Over certain types of rough payment, it sounds like a handful of marbles vibrating in my dash. Does anyone else experience a similar rattle? Rattle starts at 0:13

Sounds like overhead console noise or pano roof creaking from back. Also, check if your dash isn't hit the glass where they come together in front.

Have a friend drive over a bumpy road while you listen.

mine was doing that when a dime slid under the ashtray

just get some felt tape for these issues, that's what the dealer does.

funny story, when I first got my CPO I noticed tiny parking tickets stuck between the window and the glass at the very bottom edge.

I used a MB tool to pull them out. About 10 of them.

Every now and then when I have the AC on high, another one will suddenly pop up and have to be removed.

Apparently, the previous owner had a habit of shoving parking tickets in that spot and not removing them.

I just found another one yesterday.

BTW the ashtray rattles even when empty.

Yup I'm doing the ashtray delete / mat replacement because of that too...

Tessa tape or adhesive foam/rubber strips can solve any rattles or creaks.

I removed my display so many times it began creaking at the bottom. I used tessa tape between trim before screwing it back on.

Ashtray is definitely a starting point. I store coins in mine, and on certain pavement surfaces they rattle like crazy. If I press down on the ashtray insert the rattle stops. Funny, sometimes if you know what causes the rattle it doesn't bother as much.

Rattles always bother me lol

GringoBling

same

i will hunt them all down and destroy every single one of them.

Get a big can of WD 40 and a large roll of duct tape. Tape anything that's loose, spray everything else.

I had my '19 in for its A service and my biggest issue was a dashboard rattle and door creeks. The dashboard rattle turned out to be the plastic cowl that attaches to the windshield by the wipers. Fortunately, it rattled when I took the service manager out for a ride. It took a technician 2 hours to find it, so they said.The door creek was fixed by removing the door card and applying felt tape.

on my C400 they felted all the center speaker stuff, they're pretty good about it

My '17 Edition 1 Coupe is creaking like an old man's knees! I had to come in here to see if I was the only one suffering. I'm dropping this puppy off at the dealer ASAP. I can't take it any more

GringoBling

they'll fix it up!

if its the window frame, but some dielectric grease on the rubber trim.

Oh man, yall think ashtray rattling is annoying, my drone from the exhuast will drive all of you guys nuts, so many rattles and vibrations when im cruising.

GringoBling

on a stock C400??

allanyeung99

No, im saying for people who wants louder exhaust. The drone is bearable but it brings out the rattles cause its vibrating so much compared to stock.

Two metal braces run from the fire wall out to the wings. The bolts will be loose if tested with a decent size ratchet. Undo all four, for good practice silicone spray the bolts. Then do all four up super tight. It is not that these rattle when loose, but rather it allows engine bay twist which then rattles the plastics together around the window and dash inside the car.

Tighten this two #10 bolts to stop cracking noise behind the dashboard when driving irregular roads at slow speeds or when stressing the chasis rigidity in slow movements, like starting to climb a hill with one wheel before the other
