My GF has an ML500 and chipped the plastic window trim. Its the black panels that are on the verticle part of the door windows. They seem to be vynil or plastic. I hope I am giving enough info for you guys to know what I am talking about. Anyway, I cant find a MB parts catalog on line that shows that part. Any help?

 

My dealer called them a "pillar decal" on my work order. Just had mine replaced under warranty as they were really faded. Shows two part numbers: 163-698-02-89 and 163-698-04-89. Guess one was front door and other was rear door. Also referred to it as "Ornamental C" on another place on the work order. Part numbers should get you close enough though. Hope this helps.

 

Thank you!
