Rattle/Clinking During Hard Acceleration While In Motion
I have a 2015 C300 4MATIC with the Luxury package. Manufacture dated 08/2014 in Tuscaloosa County, Alabama (US).
While I do not accelerate aggressively often, when I do there is a loud high pitched clinking and rattle from the engine bay. It sounds like tinking an empty soda can, and is quite audible.
This happens while I am already in motion, doesn’t seem to make a difference what speed I am already driving at. I have never “launched” the car from a complete standstill, so I’m not sure if it happens then or not and I would rather not see if it does.
It only makes this noise for 2-3 seconds when I first press down hard on the throttle, especially when I truly go almost full throttle. Once again I do not do this often but it is still concerning.
After the initial few seconds of acceleration the clinking goes away and does not come back, even if I slow down my speed and accelerate hard again.
Has anyone else dealt with this issue and maybe has an answer or some insight of any potential issues to deal with?
Unfortunately I don’t have any video or audio clips of this right now, but if someone would like me to take one I can later today.
I’d really appreciate any insight you guys have, thanks!
