Excuse my thickness, what does a 2001 2.5 V6 TDI have? Its the 110kw engine.

The later TDi engines (2000/2001-on, not exactly sure ) dispensed with the big high pressure rotary diesel injection pump and became the pumpe deuse (PD) engines as these had a small pump/injector unit on each cylinder instead, which gave more power.
Until today I would've thought that a 2001 V6 TDi was a PD engine, until I looked the engine up on ETKA and saw only the 4 cylinder 1.9 engine was a PD unit; at that time the 6 cylinder diesel retained the older style injection-pump arrangement.
Hope this helps.
