air con pump replacement

[big_tedman]

When replacing a aircon pump in a mk4 gti, how similar does the pump model have to be?
mine is a 1J0820803F
have seen a few pumps but with a different letter at the end, such as a E or J
dont want to get the wrong one

Can anyone answer? i cant find any confirmation on this by searching.

The last letter is a modification letter so different and revised editions. Without knowing exactly what thoses revisions are it would be hard to say if it should work but generally it should be ok. ECS says that part number has been superseeded to a k revision so should be sweet. But as always make sure.

Cheers mate.

Mine was an A revision pump (1999 build), I emailed ECS and they said that to use the latest revision pump I'd need to change the belt and condenser as well (different pulley/pipe connections?). As Back Door says, best to check with them first.
