Toothed / timing belt replacement schedule?

Hi All,

Does anyone know when the toothed / timing belt on the 170CR Superb II should be replaced? The service schedule book seems to suggest every 180,000km, but seeing as I only do roughly 3,000 miles a year, it'll be a long, long time before I get to that point! I remember when I was looking at an Octavia last year that I was advised they need the timing belt replaced every 4 years.

Kind regards,

Declan.
