Yes, the serpentine belt.

Already done. Unfortunately was away from home, so it cost me heftily - 2

Nice to see that older tensioners still hold, so I don't have to start
replacing them on my older VAG products. Serp. belts I've swapped as
prescribed.

Thanks to all and mat your belts/tensioners hold together.
