They have a chain driving the cams, but there is a belt driving the fuel pump.
 

RAV tdi

Audi A6 3.0 TDI '05 - Audi 100 2.8 quattro '91
V6 tdi motors have chain for cams but too they have two belts, one poly v belt and one toothed belt.
Poly V belt is for move aux. elements.
Toothed belt is for diesel pump. The chain driving doesn't need changing and belts need changing after 90,000 miles.
