I have a 2015 Q7 roof rack, but no longer have the car. An acquaintance has a 2009 Q7 but we don't know if it will fit in his car. Does anyone know if they're compatible? He lives a bit far and I want to spare him the drive if it's not worth his while.

If you are talking about:

Then, yes, they are compatible. If you click on the "More Info" button, it lists all compatible model years. This can be used to check the compatibility of any accessory.
