It's for ML 350 2014. I lost the left one.
I searched on Ebay and couldn't find one. I only need the plastic chrome cover.
Thank you!

I think you are looking for part labeled 510 in the attached picture.

Part number for LEFT trim is A1668850774. Check with your local MB dealer, it shouldn't be that expensive.

I just found your cover. I think the seller found it on the road and listed it for you to purchase it.

Thanks! This is exactly the part I need.

Great! I just saw this. It seems a defective one. It has a broken tab. I will think about it.
Thank you!
