The DME is under the hood, just under/near the windshield. You have to remove the pollen filter/back engine tray to gain access.
Acording to RealOEM.com your car has the MDS81 DME.

Easiest thing would be to use a OBDII scan tool like the BavTech to read your DME. The BavTech cable will tell you which DME you have. It won't tell you which SW version you have unfortunately. Any dealer can read that for you.
IF you have had a SW update anytime since 2011... your car most likely has the new 'anti-tuner" SW added. Do you feel any Lag? Then you have it.
Here is Burger's video on how to get at the DME...
