From what I remember when I changed my CS paddles to the R ones, there is a pin like the mk7/7.5, however, it’s further inboard under the airbag.
I looked into this a bit myself before going for the R paddles as a work mate has the Racing Line paddles on his Polo GTI, they’re nice.
For what it’s worth, the R paddles are worth the upgrade! If you find my and others guidance on here it’s straight forward to do. If I recall, the most import step is DO NOT turn on the ignition with the airbag electronics disconnected, you will get an error that requires OBD to reset.
I didn’t get an error, some did, I think we worked out it was the turning on the ignition with the airbag on the passenger seat that was the difference
