    I had some time yesterday so I had a poke about at the engine of my new 1.8t and whilst doing an oil change I noticed that the very small belt from the power steering pump to the water pump is a little slack but I cant for the life of me see any adjustment for it. As it is at the moment it's ok but I can see it wouldn't take much to stop the water pump turning. Is there any adjustment to be had or is it a case of fitting a new belt?
    Also noticed there is no belt fitted to the air-con so that needs investigating as to why....
    On the upside I cured the misfire/hesitation I was getting at 3000rpm. It was a short piece of vac pipe off the intake manifold to a valve thing on the fuel rail.

    Even with a new belt they are far from tight. As long as the pump is turning freely i wouldn't worry as the belt will still turn it without issue

    As for the AC, its quite likely the compressor has siezed, and the belt has been removed, or burned thru and snapped.
