I just got this xD and have been going through every manual I can find on the car trying to find out what bulb numbers were used where. Even the factory service manual doesn't list them! I finally found a usable list on RockAuto.com. I condensed it into a .docx file. This only covers the 2008 model. I don't know if the later years differ or not. You'll have to do your own detective work for newer year xD's.

Hopefully the list I made will help someone.

Hmmmm. File upload doesn't show so here's the list. Finally got a PDF version to load. File is attached.
