I'd go for the new father in law and water pump personally, it sounds like he's trying to helpful (bless him) but is actually making an arse of things, go into the faq and look in the 99-2004 jetta faq, you'll find the guide in there for doing the belt properly and also how to replace the waterpump. People like to be helpful but sometimes they just don't have the knowledge, I've almost fallen out with some over engine stuff. One guy, an old mechanic supposedly argued silly with me about hone marks in the cylinders, he reckoned you just did a rebore and that was that, he wouldn't accept you have to use a special tool to hone the cylinders after reboring. (Honing makes cross hatch marks on the cylinder walls to help with holding the oil on the walls to aid compression.) I don't know if it's to do with marbles and losing them or what.
