my new benz got stuck in the mud the other day
was able to get it out with some guys lifting the rear
i did have to use some high rpm's

now i am paranoid that the engine is making this new high pitched sound when I accelerate
is this a normal sound i used to just ignore especially with the a/c and radio on. can someone check their car and let me know if this is a normal sound.

thanks

You went mudding in the W211?
I don't think high-rpm's will hurt your car.





What kind of sound, can you trace it?
