1.4TSI 16V petrol engines should be from the EA211 family of engines, all of them should be covered by the change in recommendations that VW Group issued a few years ago, ie the original cambelt must be replaced every 5 years, was dropped to bring the cars supplied to UK owners in line with what other European markets recommendation was.
So, if I was in your shoes, I'd consider what that was, there must come a point in these engine's life where replacing the cambelt is a good idea wrt to preventative maintenance - my wife's August 2015 1.2TSI 110PS Polo, is currently at roughly 54,000 miles, I check the condition of the belt at every yearly service, but I might consider getting it replaced this year - just in case, I'd only do that if I felt confident that the Indie I got to do that job, has the special kit and is comfortable with doing that job as too many owners have been left with a rather "dull" engine after getting that job done!
