    Hello everyone,
    I have an e400 2018 with 9700miles. I absolutely adore the car.. I bought it second hand and it has a rattling noise when i accelerate, both when in neutral (which Mercedes say is normal) but in a similar way it is much louder when accelerating in Drive @approx 1400-1800rpm.. It is not a nice noise but Mercedes says it is normal. It sound rattling lie something will fall off the car. Does anyone have a similar problem?
    I tried a new one yesterday and the noise is 10% of what mine has. Mercedes says it is because the mileage is much more.. i think 9000 miles is not a lot for a car like this.
    If it is normal I can't believe no on else has complained.

    9/10k and a 2018 car is anything but used in my book!
    Any way you could post up the noise? Where does it seem to be coming from?
    Sorry, should have said ‘welcome’!

    It could easily be something like a loose exhaust heat shield.

    That sounds like a typical Mercedes initial response for any problem - it’s normal. Sadly, they probably adopt that attitude even more when dealing with a lady customer.

    Did you buy it from Mercedes and, if so, when? Assuming you did, then you need to make a real nuisance of yourself. Insist on seeing the General Manager (or whatever the top person is called these days) or create such a fuss in the showroom that they take you seriously. Your own investigation has shown that it is not normal. Good luck!

    PS welcome to the forum.

    The advice is often to do this via YouTube and then post the link .
