Tiguan automatic - should I change the gearbox oil?

I have a 2009 Volkswagen Tiguan diesel automatic, but I am getting different conflicting information on the gearbox. Is it a DSG? Should the oil and filter be changed? I've taken it to a specialist and they've told me the oil cannot be changed.
Even though this has the more reliable 6-speed wet clutch DSG, the transmission fluid and microfilter still needs to be routinely changed every four years.
