2015 E Class AMG Line Night Edition
Loud cabin noise! Help
I have recently purchased a 2015 (65 plate) E220 Blutec AMG Line Night Edition with 47,500 miles on the clock.
My issue is that it seems to sound like an old hackney cab when idling and driven at low speeds. I've had it for three weeks and at first just thought it was normal as its my first diesel car.
But the more I drive it the more I think there is no way that a luxury saloon should have such engine noise in the cabin.
I have taken the car to an Indy Merc specialist in my area and he had a listen to the engine from the outside and says it sounds normal for the OM651.
I've had a look at a few Youtube videos and the only one which kind of replicates m y experience is
- skip to 4 mins to hear the driving. The comments suggest that the sound has been amplified in some way.
I guess my question is, is this normal? And if not any ideas what could be causing it?

That's what I was thinking! Did it do that while you were test driving it? Maybe go find another used Benz for sale with the same engine and test drive it? I know when having a diesel some engine noise should be expected, but WOW!

I'm not sure if that video is a little bit dramatic but from the two reactions I can see it's definitely not normal. Here is a video actually of myself starting the car and travelling 50 yards at 10mph.

I suggest having engine and transmission mounts checked. One or more of these being collapsed can cause a lot of cabin noise from the drivetrain and it’s a common issue.

I have no experience with diesels, but another thing I would check or have checked, is whether all of the under hood and under body sound insulation panels are in place. If the under hood blanket is missing, or if panel fit is not right, a lot of noise could intrude into the cabin. Also, do all of the doors and windows, along with sun roof, seal completely?
My car is anything but silent, but a lot of my noise is from the suspension. I have sport suspension with steel springs (no air suspension), so if I run over a matchbook, I can feel and hear how many matches are left in the book. With this setup, I am constantly chasing minor creaks and rattles, as the suspension just beats the car loose. Great car on smooth highways, not so great on the cratered city streets where I live.
