I have a Jaguar S Type R and someone stole a small panel off the front bumper and I need to know what it's called so I can replace it. The back of the small exterior panel says 4R83-17E810-A %26gt;ABS%26lt; R/H. What is this part called? I don't want to go to a Jaguar dealership because they're rediculously expensive, please help!|||Well if your going to go to a salvage yard, have the person working there go out to your car with you, if they can, and identify the part for you. It's kind of hard to ID a part with out info like the year or seeing a picture.
