Is a loud engine normal for an E350 Sport?
They didn't rack it. Just popped the hood and took it for a drive (with me pointing out the noise).
It looks to be in pretty good shape to me. While there is just a tiny bit sagging forward, I cannot imagine that's responsible for the noise I am hearing.
local mercedes dealer is a joke. Told me I needed $2600 of work without visually inspecting the car - recommended a bunch of stuff based on miles.
have you listened to the recording? I would be a tad bit surprised if that sound is because of mounts, but, hey, I'm new to this, so that's why I'm asking.
Mounts are easy on that car. Don't look for a magic fix, just fix the actual issue.
He was estimating based on the amount of vibration on the steering wheel.
While I definitely would have preferred a visual inspection, he seemed to know what he was talking about. No?
Problem solved.
What I've learned:
- I am more sensitive to sound than most people. Some other Mercedes owners (including 3 Mercedes mechanics) thought the sound was normal. I knew it was not (and I've owned a Mercedes for only 4 weeks).
- Mercedes cars can, in fact, be almost as quite as Japanese cars in the cabin.
- Where to get my Mercedes fixed. I found an awesome mechanic who was really understanding and fixed the issue for a fraction of the Mercedes dealer's cost.
- These forums are quite helpful. Thanks to everyone for your input!
- @ItalianJoe1 is the man! He was the first to call out the fix and was right on.
Here's video after the new mounts, in case you want to compare to my earlier video

. Did you notice any difference in the smoothness of the shifting?

I have not yet noticed a change in shifting. However, I just had the mounts installed, so I was paying more attention to the sound.

Theres definitely a big difference.
Also, my 2016 E350 is very quiet from the interior. (The engine seems to be noisy/slightly clackety at standing idle from the outside... Maybe I’m over sensitive!)

Was it under warranty ? or How much does it cost you to replace Engine mounts ?
My indy tech told me this will need 9 hrs to replace engine mount.

I purchased my 2016 E350 with 30.000 miles 4 months ago, and I have the same noise, coming from the right side of the cabin, throttle-like sound exactly like the one in the video. I'm sure that the mounts are still in good , and still confused about the noise. Sometimes it's bothersome. On higher speeds and RPM, that sound disappears, and the car is quiet more than multiple cars I've driven. Its only occurring from a red-light stop or city driving at lower speeds. Anyone found solution? I took it for inspection when purchased and thr mechanic said everything is fine.
P.S. my previous car was 2010 E350 with 140.000 miles and it didn't sound like that at all. By the way, I test drive a 2013 E350 and sounded loud as this 2016 E350. Is it the new engine for that model with higher torque and horsepower "just" louder? Or is something wrong? Thanks in advance
