Indeed. Confirmed the part will be sourced from Germany.
I will pick up my car tonight and wait until the parts arrive.

After 24h of testing, my service adviser called this afternoon and informed that the dash noise seems to be coming from the strut. They ordered some parts for tomorrow plus some special grease to apply to see if it fixes it. Fingers crossed.

Spoke with my (future) service dept today to get some maintenance costs on the GLC and when I asked him about any issues with the GLC, he mentioned the strut, so it is apparently a known issue now.

My service adviser also told me the demand of GLC strut is on the rise. He thinks MB knows it's an issue by now.

Had my GLC in for service today for the noise. The service guy heard the noise on his test drive. They had a service notification about the noise so it must be known. All they did this visit was to apply special grease and mold lubricant to surface between spring and spring support. We'll see how long that fix lasts.

Noise came back....

I have driven mine for about 1,500 miles since the repair, and the noise came back... I think I'm going to see the dealer again...

I think he did not have his strut replaced. Dealer did a different type of repair.

The dealer will probably tell you it's an echo from another car hitting a pothole.

For those of you who have had the strut issue, were they able to diagnose the problem by visual inspection of the strut or was it by noise only?

Sounds like my GLC has the same strut issue as other posters in this thread. For anyone that has been through it - did your dealer say what actually is the cause? Bit hesitant to continue to drive the vehicle - calling the dealer tomorrow but usually getting a rental isn't instant.

My GLC probably started to have this noise too. I've noticed it twice, both in the afternoon the day of around 70F after driving/parking in the sun for a few hours. I haven't heard of this noise in the past 2K miles. So I'm not sure whether the miles or the temperature matters. I tried to record the noise, but record wasn't very clear. So I have to do it again. Otherwise, I guess I won't be able to show the noise to the dealer during servicing.

If anyone has recorded the noise, would you mind sharing the sound file for others like me to compare?

work order

Attached is the work order done on mine.
So far, the creaky noise (over bumps or uneven road) is gone.

Hope it helps for diagnosis on other GLC.

I too have the dreaded "noise from dash". To my ears it's obviously suspension related. I have a service appointment next week. It's easiest to hear when I'm going up a very steep neighborhood hill or when the road is uneven and one side of the car dips then recovers - below 20 or 25 mph. I can also hear some barely perceptible creaking at moderate highway speeds.

Thanks Maylin! Called the dealer - the service adviser who I have had 8 years of extensive history of repairs with with my previous 07 ML320CDI stated that they never heard of this problem before . The two R/Os in this thread should help. Keep you appraised of what happens. I'd rather not have the dealer starting to remove my interior because at least THAT doesn't rattle now. Thanks again!

Mine is standard suspension too. I'll get mine fixed next Tue. Hope the new strut is form a different supplier or good batch.

In my case, the creaky noise was very hard to hear then getting louder over ~1 month. Now I can hear it even with radio on. If you have bad strut, don't worry, it will show up eventually and very hard to ignore.
