The service invoice has my personal info and VIN all over, so I'm not going to post it directly. But the sunroof fix (basically clean and lube everything) was the only one that I'd want to tackle myself. Everything else was definitely a dealer fix--I wasn't exaggerating when I said they put in a week of tech time to tear everything down.

10 painful days, but worth it.

My Canadian 2017 May-delivered C43 had a whine that I noticed during break-in from day 1. The worst was when running at about 83 kph, regardless of running gear and when running at about 50 ft. lb. of torque (by engine data display) -- i.e., it whined incessantly when cruising at certain speeds on a flat road. I notified the dealer but told them I'd leave it 'till the car was broken in and our initial 4K km. trip was done (hoping maybe the gears just needed some wear-in). By that time the whine was at 57 kph, 83 kph, 113 kph, and more. I thought it was strange to have a fairly low-torque-specific whine, but there it was!
I took the car in and the dealer verified the whine during a test drive then tracked the whine (using dyno mode while on hoist) to the rear end (as I'd guessed ... and likely better than the other guess, the power-take-off gearing). MBZ told them to first change the rear-end fluid. That had zero effect (as I guessed it would). Then they replaced the rear-end/differential gears.
I'm still running through some break-in mileage for the new gears, but after a few hundred km., the whine is still gone so it's likely fixed.

I haven't been able to find the whine, the last thinking was that maybe it was the BenzConnect Speaker in the middle of the dash, not the integrated speakers for the sound system.
I've also just done an AMG driving academy day at Laguna Seca. Lots of technical course stuff, plus time on the track. At the end of it, on the ride HOME no less, I now have another noise coming from the rear. A wowowowow type of sound coming from seemingly back LEFT not necessarily just BACK Speed changes with speed, so i'm HOPING that maybe it is just all the Klaggg that was built up on the tires (there were a lot of performance cars there with track slicks making quite a klagg strip just outside the optimal line - where I spent some time being a sedan not an SLS, SLR, SL etc. It DID seem to get better after driving about 80 miles home, but it's still there.
I can see the line of klagg mostly on the outside tread line and some inner. It's NOT totally uniform so that could be where this new sound is coming from. It's loud enough to cancel out the typical exhaust throat noise, at least it was at first. I'll give it a week of driving before I take it in for a look see.

Picked up my C43 back in March 2017. I heard the rattles the moment I drove out the dealership. I knew the W205/C205 platform tend to have a lot of rattles, but the AMG sports suspension made it hella worse than normal C classes. Although I did come from a BMW 5 Series, so my standards for rattles in the interior are rather high.
Anyway, decided to take it into the dealership to fix all the damn rattles. Not only did they fixed the rattles I brought up, they went above and beyond and fixed some that I didn't even know about. However, new rattles came up recently, so I took it in again this Monday, took them 4 days to fix all the rattles. THE CAR IS DEAD SILENT NOW!
I have attached the work order sheet for the rattle repairs, I hope those who are currently struggling with the rattles will find them useful.
Kudos to Mercedes-Benz of Fairfield!

It gets completed by a dealer.
Same as my 2016...
all the rattles were fixed by the dealer.
And there are still minor cosmentic issue (lighting) that are going to be addressed by the dealer.
I hope the car is reliable after the warranty though

I went to MB Marin for my rattles (there were several) when my car was under warranty. Based on my experience, MB Marin did a thorough job addressing my concerns, as they fixed all existing rattles, and kept my car an additional day to make sure the job was done correctly (it was also there for a B service). I first tried to get my car rattles resolved at MB Pleasanton, and while they were OK, MB Marin was ultimately the dealer that fixed everything for me.

Old thread and post I know, but... San Francisco MB sent me on my way with a list of "could not replicate..." notes on the invoice, and as I rattled my way out of their parking lot I considered taking it to Marin MB instead, mostly based on the initial reviews from a quick Google scan, but it looks like that's off the docket now. At this point I'm hoping the OP meant Fairfield CA, in which case I'll drive the hour to see if they can "replicate" his experience with my car.

check that your passenger headrest isn’t rattling when I found out it was an issue they just ordered a different one but wind issues took several tries and visits otherwise give Fairfield guys a try , they really impressed me and don’t bother with San Mateo ! They are probably too busy like San Francisco so they will just do a hard eye roll as soon as you leave.

the keeping the car for an additional day is usually because they forgot to do something , I wouldn’t read too much into it lol fit one those things that tracks your car so you can see when the car is started or just a dashcam.
they are good folks but car usually sits untouched , just lucky that my service advisor is honest lol so he tells me when they forget stuff , I think he trusts me probably cause I always give them good survey.

sorry I didn’t mean to discourage you ! MB of Marin has good people if you are under warranty give them a chance then drive to Fairfield if they fail , just understand that they seem to follow a script so basically write off your first 2 visits cause they probably won’t do anything but if you are lucky they get It done by your second visit and not third.
