Water Pumps KV/KU

[Brian Mole]

I'm having a nightmare trying to buy a water pump for my '89 coupe.
The problem is that the car is fitted with a KU engine (Audi 100, I believe).
According to Europarts, there are two different pumps fitted to cars
with this code, can anyone confirm this? It looks like I may have to
take the old pump with me. BTW, they are quoting 15UKP for the
pump which sounds worryingly cheap to me, has anyone tried
one from them or should I go for a genuine item?

Regards
