The trouble I feel is, many many people will have had small VW Group cars from earlier times when 4 or 5 years was the advice and felt the need to take that advice onboard after hearing bad tales of idler pulley failures leading to big engine repair bills, I certainly looked after my wife's 2002 VW Polo 1.4 16V BBY engine, and taking what sounded like sensible precautions worked for me and so for her car we paid for 2 "belt" changes, I advised my older daughter to do the same with her 2009 SEAT Ibiza SC 1.4 16V. I examine the cambelt at every service and have done since it was 3 years old, but I'm thinking that 10 years is maybe enough and I'll aim to get the belt changed later this year. Being realistic, I'd expect that we will move this car on when it is 15 years old, so if I get the cam belt replaced, I'll have had some benefit from doing that work. I'm just trying to minimise risk while not "scattering" cash. You rightly feel sore about being con'd into changing that belt at the 5 years point, but you should not now feel the need to revisit this area for the rest of the time that you have already suggested/hinted that your wife will keep this car. Just different situations for different owners, my suggestion was aimed at a new owner of a used car.
