Hi,
We have just had the water pump, cambelt and tensioner replaced on our Golf Anniversary (52 reg, 31000 miles). The water pump went over the weekend.
The water pump was replaced under warranty, but they asked us if we would like cambelt and tensioner done at the same time, to save on labour costs later.
I queried them about the 80K miles thing, but apparently (and I checked this with a quick phone call to another VW dealer) that there is a new directive regarding cam belts. The directive is: replace after 4 years old, regardless of mileage. I can only assume that this change-around in policy must come from failures.
Which has me slightly concerned about my S3, which is 4.5 years old, and 45K miles.
