just wanted to finish my update.
The dealer replaced the Trans and also checked the torque converter which they chose to replace also. All in all 100% covered under warranty and it took them 3 days to do the replacements.
It was a day and a half of work and about a day and a half to get the parts in.
Its as smooth and quiet as I remember when I bought it.
if you hear whining above 30 mph.. take it in.

Can you describe what your whine sounded like? Was it a constant whine? Mine tends to have some whine at low speeds (below 25 mph), and even then only around the shift points. My SA said that's normal for 4matics. So if yours was similar, and your SA decided to replace the trans, I might make the drive to West Covina to have them look at mine.
Thanks.
Thanks.
I took it into the dealer to just check and when they put it on the rack and took it up to 70 it was VERY apparent to them that bearing in the transfer case was gone. At 70 when I drove it the road noise didn't let me know it was an issue.
im glad I had this checked, but according to my SA its very rare, he had never seen a case in his service center but the TSBs are where they located that MB was aware of it. They were able to diagnose it ultimately by putting it on a rack and having tech underneath as they took it from 30-70 mph.

could be, I guess my comment was really that Penske in West Covina is a very large service center in So Cal and this is the first case they have seen on a 2010 GLK. They sure didnt put up any resistance to replace not only the Trans but also the torque converter.

BS.
My GLK 4Matic is dead quiet.
My C300 4Matic was dead quiet until the deathwhine started, they replaced the tranny and it was dead quiet again.
My wifes's E350 4Matic is dead quiet.
Now, rule out other things. It is very hard to determine where a while is from inside the car. Rotate the tires and see if anything changes. Listen during a sweeping turn or going over a whoop. Weight shifting may cause changes in noise if it's a tire or wheel bearing, but shouldn't if it's in the tranny/transfer case.

Folks, my 2014 GLK250BT is experiencing a very faint "whine" that is definitely speed-related. I'm wondering if this might be a sign of an issue? A couple of things to note:
1. I notice it MOSTLY when I'm coasting. That is, if I don't apply power and slow down only on air resistance and friction, I can hear it on some days. If I step on the power again, I don't hear it.
2. The noise reminds me of front differential whine that I've heard on every 4WD/AWD vehicle I've owned until I bought the GLK.
3. I'm not sure if it's from the tires, but I believe I've heard the noise with my winter tires as well.
4. I have extremely sensitive and picky ears. I hear everything. The slightest anomaly (see my thread on cavitation/resonance with this car) is very audible to me. Perhaps the 4MATIC system is operating normally and I'm just extra-sensitive.
Any thoughts? I have about 12K miles on the car now, and would like to draw on others' experience to see if I need to be watching this more closely. Any people with the facelifted 204 experiencing this? Thanks!

I also have a GLK250 BT (2013) and have this exact symptom. Just started noticing it. I have about 22,000 on the vehicle. Did you ever find the issue, or just living with it or decide consider it normal ?
