Scirocco Central

Hello, can somebody explain me the difference between 137 or 137, 138. Or how can I know which one I have. Thanks. I could be wrong, but I'm sure all the pre-facelift Scirocco's are model 137, and the facelift from the end of 2014 are 138 Oh thanks, mine is 2014, I should check out the serial numbe...
