AFN / AHU coolant pipe differences

[expat2000]

Hi all

A coolant pipe on my 1998 1.9 TDI (AFN engine) let go this morning.

Looking up the part number on partsbase I came across this:

1	028121053K	coolant hose; (flange > oil cooler >; coolant pump); 1Z,AFF,AHU	1
1	028121053AA	coolant hose; (flange > oil cooler >; coolant pump); AFN	1

Online sellers seem to have plenty of the K variant for the 1Z/AFF/AHU engine but cant find any of the AA variant for the AFN engine.

So the question is does anyone know what the difference is. I have tried seaching the forums but its quite a detailed question. Nowhere can I find any specific differences in the cooling system between the engine variants. All the pictures I can find online look very similar so I am wondering if I can use the AHU variant?

For reference the partsbase page is here: AUDI A4/AVANT [A4] (EUROPE) 1996: ENGINE: 12140. COOLANT COOLING SYSTEM

Cheers

Stuart

No difference but you could double check with a main dealer
