multiple water pumps and disks + pads?

[Me9141]

Getting some parts under trade as my mate is a trader.
Apparently there are two sizes of disks and pads for the polo and two different types of water pumps.

Anyone know how I can find out which ones I need?
It’s a 1.4 tdi twist, 53 plate (2004)

thanks in advance

Ask your friendly Parts Dept. at your Dealer?

This is a bit late, but, lets think about this, you know that the car is a 1.4TDI 53 plate, it must have a vin identification, any supplier will have a vehicle application list which will be able to discriminate between variants - so you should be okay. BTW if your mate is a trader and he has not worked that lot out, then personally I'd just buy from a VW dealer directly.
