GLS 450
rattling noise while accelerating
Hello. I am new to this forum and would greatly appreciate any help and insight that you can give me. I have a 2018 GLS 450 that has done around 17000 miles- bought it when it had done 13000 miles. Since I had it- there is a rattle upon acceleration when the turbo starts spooling. I have taken it to two different dealerships- the latest thought is that this is a rod in the left waste gate that is rattling when the waste gate is in the open position. Mercedes Benz says that since this is not affecting the operation of the car or performance, there is nothing to be done about this. They tried a software update that did not work. I am wondering if anyone else had this issue and if there is any solution? it is very disappointing to hear such a sound in the cabin while driving- you do not expect this in a GLS. There seems to also be a loud hiss from the turbo when in sport mode.
I would be grateful for any thoughts on what I can do.
thank you
