I can confirm that the VW part is identical in fit and function to the Jag socket. I just picked up two of them from my local VW dealer for $7.50 each (Canadian.). That's about 4 bucks each using current US exchange rates!

Not worth a trip to the wrecker's, even.

My local Jag ******* wanted $149 CDN for the full side marker assembly. What a ripoff.

Thanks for the great tips everyone -we Jag owners need to stick together.
