Chirping sound!

Post by laszlo_papp » Sun Dec 09, 2018 4:19 pm

Any ideas / guess what may cause this.
Sometimes it dose it and sometimes not.
But allways only in park. When put in gear the chirping stops.
Facing the engine it comes from the right side somewhere from quite low, behind the wheel.

I’ve got the same thing. Front right side when parked and hot. Pfl.

My dealer said they couldn’t replicate it and it’s been 9 months of uselessness.

Not sure what to do either sadly. My Mercedes experience has been really bad so far and I’m really thinking of ditching this car and getting something else.

Although mine is not as loud as in this youtube video but sounds similar!
Apparently an oil overfill can couse this!
The expanded oil pushes outwards on the main crank seal and that will rub onto something!( Sorry im not to clued up on tech terms).
I have read this yesterday online.
Sure enough my oil level when at operating temperature its very slightly over the maximum read.
Will try to get some oil out see what happens.

Where’s the auxiliary belt on one of these? Maybe the water pump also? Just trying to think of other cars I’ve had where vaguely similar sounds have occurred
