Hi all

I bought a C350 d Estate and when I start the engine, it sporadically makes a loud revving noise like a motorbike is going past. It does not do it all the time, and doesn't seem to do it after any particular journey or run time.

Video of sound below:

If you have any ideas, please let me know.

The vehicle has not been modified to my knowledge, and does regular long journeys.

Brilliant
You’ve the Mercedes Me Adapter on your iphone/Android phone haven’t you?
This is the ‘connecting’ sound it makes.

It is indeed- if you tether your phone too, you can get that sound through the ICE system, sounds awesome!

It's not April 1st, is it?

Getting into one of mine, I hear a loud voice that states, 'Connected'.
The strange thing is, it even speaks when I've left my phone in the house.
Rather have a voice than a rattly noise.

It doesn't do it every time though, which is weird.

Yeah neither does mine, just when it feels like it! I think it’s when it’s connecting, and sometimes it stays connected for a long time.
If you go into the app, choose settings - General points - Vehicle- you will see ‘notification sound at start of journey’ - the one you have now (as do I) is the “mercedes me sound”. You can change it to tritone or no sound if it bothers you....
