Gummi Pflege may work but will be temporary. The Mercedes Sliding Compound (rebranded Krytox 105) should last way longer (it silenced my pano roof). Krytox is used on spacecraft as a permanent lubricant...

I took it to the dealer and the tech said the right rear shock has a "dead sound" and ordered the part. (we will see)

I have a 2016 GLC 300 with a rattle coming from passenger side cargo area. I took this video holding my phone near the small window in the cargo area on the passenger side. Does this sound familiar to anyone or any ideas what might be causing this rattle?

i have the same issue with the above compartment rattling and ticking noise...they checked it and said the harness for sunroof was lose and re applied some tape. but the sound is still there...its really annoying but it seems like MB is brushing me off saying that its "normal" here is a video clip of it if...i transfered it on to this site but its kinda hard to hear it...anyone else has same issue as well?

thanks

Last Friday I took my CPO c300 to the dealer for various issues including a small fuel leak in the engine bay and the annoying squeaking noise from back seat area, when going over bumps (right side)

The MB tech sat in the back while I drove over bumps. I heard the noise clearly, but he claimed to be unable to find it's exact location. Nothing was done.

Is 50mm the right thickness?

benzdude

I think its my pano roof that's doing the creaking. I decided to drive with it open and the noise went away. Only creaks when closed. it is snowing so I can't do more testing.

Can you indicate how/where it was applied? Did it require disassembly?

EDIT: After doing some research, I now understand how to apply it.

GreekUPS

You won't be able to get every inch of the pano roof seals, its kinda tight. I put some on my fingers to reach some of the tougher angles.

benzdude

Success! I opened my sunroof and ran my fingers around the seals a few times (applying pressure). I also put some pressure on the part show below. The creaks are gone for now. (I also ordered the gummi bear phlegm).

Thanks GreekUPS. (peace and quiet!)

Is Gummi Pfledge similar to silicone lube?

GreekUPS

"Nextzett Rubber Care Stick “Gummi Pflege” is a real standout product among rubber protectants because it is water-based and non-silicone. Silicone gives rubber products their shine but it attracts dust and dries out the rubber over time. Nextzett Rubber Care Stick protects the rubber under a safe, water-based formula that does not attract dust and it’s healthy for the rubber."

thanks guys!

MBSebas87

just got it in the mail. How often do you guys apply this thing? Every 6 months?

GreekUPS

I applied it once when I got it. That was 2 months or so ago. Pano hasn’t made a peep since. I plan on applying it on all rubber seals once I get my car detailed this spring.

Does anyone have a creaking sound coming from inside the dash up near the windshield? I've checked / fastened /felt taped: the defrost grills, the center speaker grill, the screen, the plastic covers under the hood and it is still creaking!!! I'm taking it to the dealer in a few days but we all know how intelligence they can be sometimes. Last time i went in for a small thing they had the car all day and didnt fix it. Thanks

bzammitt

Sorry, that's just kind of funny

j0hn galt

and here I got all excited when I saw someone replied to my post! and oh man I could go on and on about them. I think it should be a prerequisite for service reps to have owned at least a German car at one point in their life

benzdude

Funny. I just heard that one tonight.

Mine is coming from the passenger side near the windshield. When I go over bumps the trim (edge near the glass) is hitting the windshield and making a rattle sound. I can reproduce it by tapping on the steering wheel (with radio off).

I applied some pressure between the glass and trim and the noise went away. I will add some of this stuff (below) between the trim and glass. (You can stick two of them together if not thick enough.)

Surprisingly the dealer fixed the creaking sound in less than an hour. They released and retorqued the support bars that run diagonally from the strut towers to under the windshield. Of corse they blamed it on my aftermarket coilovers even though the noise was happening before. Whatever $170 and it’s fixed

Brittnie Jane

Mine is in now for this exact issue! Plus other mechanical failures

JAMADOR

Noticed a slight creak in my dash yesterday, fairly consistent as I was coming to a stop.
From trying to reproduce it, I think it's the motor/actuator or door for the recirculate setting.
Anyone know if the A/C defaults to recirc when the auto-stop activates & turns off the engine?

Now that it's warmed up quite a bit here, noticing a bit more sunroof noise, mostly right after closing it, before it's had a chance to 'settle' then it slowly gets less & less.
