Edit*** if it was replaced 20k ago you really should be good***. Actually looks pretty good. However, it is hard to see any separation from a still picture. Under the Treg push firmly one way then the other (side to side and up and down) on the driveline and watch for any separation in the areas where rubber bushing meets metal (carrier and bearing housing).
VW did a poor job in making the metal to rubber contact points substantial enough to take this type of repetitive movement over many, many years of ozone exposure. Once separation starts it gets exponentially worse very quickly.
If you really are concerned remove the metal plate (I think it is like six screws) and you can get a better visual. This will allow a gentle manipulation of the carrier bracket (as it will no longer be bolted to body, you can use less force).
All the above in perspective, your CMB does look to be in good condition.
