Folks,

I just traded my 2015 C300 for 2017 E300, I have little over 500 miles on my E300 and have owned it for over 3 weeks now. For some reason the engine noise in the cabin sounds like an old car. It has an AMG exterior pkg with 19" AMG five twin-spoke wheels, not sure if they are the cause but it really sounds like an old car. If I am stand outside of the car while engine is on then it sounds ok. Anyone else has this issue?

 

Are you talking about extra loud clicking noises, exhaust leak noises, rattle noises? Need some more info here.

 

Sorry I think I am describing it incorrectly, actually I shouldn't use term 'noise' but rather general sound in the cabin while driving is similar to driving an old car, it is humming like an old car.

 

Check the data card for your build to see if it has B63 - engine noise over speaker.
There are several thread that discuss the topic.

 

Yes, it does have B63 option, is that causing the cabin sound that way? Can I do anything about this?

It cannot be turned off!

A different controller is needed. There is a thread here somewhere with a part number.

 

Well I don't have that issue like you, it sounds almost none when I'm inside.
But if I stand outside by the front, engine just sounds bruh....bruh...... like it's working too hard at the moment haha. Dont know why? About to take it to dealer to see what's going on.

 

Hi new owner here myself. I will put an intro email up shortly, but I have a question and comment.
They really ADD the engine noise over the speakers? Why in the world do they do that? Seems very odd.

And second, where does one obtain "data card for your build"?

 

Post VIN or https://www.datamb.com/

 

Yes I'm experiencing the same thing, noise at above average level inside the car. I don't know why either. Anyone have an opinion?
