Help: Plastic part identification / CL65
Does anyone recognize this plastic part? It has the remnants of a part number but all that is legible is "220".
It is off of an '05 CL65. I parked and it dropped out underneath the engine compartment area. It may have been previously broken and finally worked its way out. I just had an ABC and trans flush but I don't this it's related to that?
Any help appreciated.
