The timing belt interval for certain Volkswagen Group engines has been increased to 125,000 miles, but according to many readers this has not been communicated directly to customers and has only been explained to them when in communication with dealers directly. There is no harm in having a timing belt changed ahead of the recommended interval - in fact if you plan to keep your car longer term, we would recommend changing it at five years or 60,000 miles for complete peace of mind.
