From memory there was the following:
1.8 Petrol - Cannot remember the bhp - 150?
1.9tdi PD - 115bhp (without DPF)
2.0tdi PD - 140 bhp (with DPF)
Think the 2.5 V6 TDI was rare if not dropped completely.
As far as options they were pretty much the same as before the facelift - facelift changes being tweaked front grille, side repeaters integrated into the door mirrors, rear light clusters altered slightly. Internally dash and clocks went from Green with orange centre display to white with red centre. All other buttons and stuff stayed green. Some models had fake wood which looked orange and horrid, L&K version was also introduced as range topper.
Cannot remember much else as I got rid of my facelift in 2009 after having 2 pre face lift models beforehand.
