When did you change the ZR on the EA211 (1.2 TSI with 110 hp)

Servus into the Rapid Forum, when looking for the car for my better half, I saw a rapid offer. It’s a 1.2 TSI with 110 hp and EZ in 2015. According to the seller, it can only be the EA211 engine series. Now I read everywhere that these engines have a maintenance-free timing belt. But now butter with the fish, how maintenance-free are they really and when did you change yours? I personally would change the ZR at the price negotiations. a 10 year old belt is actually a big risk. Or is ma actually taught a better thing at the Rapid? Thank you in advance and always good driving
