Please help, any one know the correct oe part number?

On the rear of the lens it reads:

2VA238039-01
6W83 13405 AF

I am not sure if these are part numbers. No match on internet search.

Thanks, tom

 

Jaguarparts.com is a good place to start your parts search. Their online catalog is illustrated with drawings so you can verify the part you're looking for. Here's the link:
JaguarParts.com :: Original parts for your Jaguar
Click on the dropdown boxes for your make (Jaguar) year (2007) and model (XK); then click on the category (Rear Lamps) and search through those parts.

Also check with Dan at Nalley Jaguar (one of this forum's sponsors) for a competitive price. Here's the link: Jaguar Car Parts in Roswell | Nalley Jaguar Auto Parts

Hope this helps.

 

That translates to P/N C2P1120, Lamp Cluster.

Cheers,
