26k miles
Front noise left side on low speed is killing me , dealer was no help
Local shop did inspection , verdict - front struts / or front upper mounts get loose
Asked dealer again to do inspection , success - dealer is going to replace both front struts under warranty
After this checked Bulletins , i think this is a common issue with these cars
LI32.25-P-051123 FEB11 – 212 without Airmatic (489), 207 without vehicle dynamics (483)
dull thumping noises or metallic rattling from the area of the front axle occurring @ speeds 10-45 mph, modified front struts should be installed.

Thanks for your reply Champlain 777. The MB mechanic had it up on the rack and he and I walked underneath and checked to see is there was anything loose. He even checked to see is there was a vibration that was caused from anything including any of the shields. He shook the struts. They still say everything looks and sounds normal to them. I still hear the noise.

Champlain,777, how would you describe the noise you had that was caused by your struts and strut mounts? Mine is a hollow sound. It doesn't sound metallic to me. The noise does sound like it's in the front left of front center.

First of all you can feel the problem with a classic suspension check
Took the car up on jacks , lock the steering column and push/pull at 3 and 9 o'clock and felt/heard the wheel move.
If case of any movement it will be probably the tie rod or front trust arm bushings ( not our case on 25k miles )
Then do the same at 6 and 12 o'clock
In our case the movement will be at 12 o'clock ( the upper part of wheel )
My Indy pushed the wheel at 12 o'clock when i touched the upper front strut and i can feel that something loose inside the upper strut on a front left driver side , 2-3 MM
Even with car on the ground sometimes I can feel movement at 12 o'clock but this one is tricky and depends of load on front suspension
Second when you drive you mostly feel kind of cracking noise ( kxe kxe kxe ) when car is cold and when you turn the steering wheels left/right on a low speed ( 10-45 MPH )
Third i can feel very slight steering wheel shimmy ( 70 MPH + )
I know it is not a balancing issue ( did road force balance ) and not an alignment issue( have it done when i bought the car )
and not a bad tires
GL !

Check out this thread from the W212 Forum, among others:
https://mbworld.org/forums/search.php?searchid=12827298
You can also do a search of that Forum for "PCM Reset." I have not done it with my car, but others there who have done it swear they feel an immediate improvement. It's a procedure you can do yourself, if it's right for your model and engine. It basically causes the Adaptive Transmission to "unlearn" previous driving behavior and resets it to original parameters.
I assume you have also tried driving in Sport mode rather than the default Economy mode and you're still not happy with performance.

Ok, mine is when I'm driving. Doesn't sound like the same sound. I spent the afternoon in the garage looking to tighten anything that looked like it could make a noise. I was sure it was a tire noise until MB mechanic switched out the tires and wheels from his own E350 with mine and I still heard the noise, so I know what it isn't I just don't know what it is. Seems like I'm the only one who can hear it. Just like the voices...

trust me even if you know what is the reason it is not easy to get it fixed by dealer
"Seems like I'm the only one who can hear it." ,- in 99% dealer will said it is normal
GL !
