Hello everyone. This is my first post and I need an information, please.
I have 2008 e350. While I was attempting to replace air filter DYI, I've noticed that my car is missing air box assembly retaining clip.

I asked my dealer and they claim to not know where it is despite I only had dealer services done on this vehicle. They don't know what this part is called and I can not find it anywhere on-line for replacement. Does anyone know what exact part number this thing has and where I could replace it?
I am afraid that there will be air leak issues if clip does not go on the air filter housing.
Thanks in advance.

 

EPC does not show/list part. Given dealer repeatedly serviced vehicle, speak with service manager to have goodwill clamp replacement (5 in diagram) if refused, contact MBUSA 800-367-6372 to intervene.

 

Thanks
