The driver side door of my 2015 GL63 makes 2 - 3 noticeable clicking noises when opening or closing the door. I have tried aerosol white lithium grease on all the obvious visible pivot points with no change.

Nothing changes on the visible hinge side of the door when opening or closing it and nothing feel loose.

I have read that on some models there is a small (7mm) adjustable bolt on the bottom of the lower hinge but I do not appear to have this on any of my hinges and there is no traditional check strap as in my W126.

It’s more of a loud embarrassment than a functional issue at this point but it doesn’t sound very good and with these cars than can only mean potentially expensive later on.

Any ideas?

Have you tried an automotive stethoscope? They are very cheap to buy, and may help you pinpoint which hinge (or cable?) is making the noise.

I've had this on my 2013 GL450 since new - almost like 2-3 stages of opening the door. I just got used to it.

I've got the same thing going on with my GL350--driver's door only. I've also lubricant sprayed hinges and slides with no apparent improvement. I'm not aware of the "small (7mm) adjustable bolt". I'll check and repost if I have it.

Don't open

This happens on my R350 as well. I noticed it started after a gust of wind blew the door open hard once. I am guessing there is an internal piece, like a sleeve, that has malfunctioned or failed prematurely due to the trauma. But I am also searching for what the fix is.

Had a door hinge clicking / clunking when opening and closing.
This is remiscent of the more normal door mechanism that involves a spring and a couple of reluctant rollers.
The hinge on my E350 2014 is nothing like that arrangement as the detent and spring mechanism is housed inside a metal cylinder.
There is a bolt on the top of the larger lower hinge, the source of issue.
If you remove the plastic beauty cap and (13 mm) bolt, don't worry, noting is going to came apart, or it shouldn't, it provides an opening for lubrication access.
I drizzled some 90 W Gear Oil into it and put the bolt and cap back on.
It took a couple of days for the lube to work it's magic, but it did and the grinding is gone. Cheap fix, you will need to wipe up any oil that drips out.
I also tried squeezing some white lithium grease into the opening and used the bolt to push it through. That certainley didn't hurt the process.
