If you fit the later revision if valve you will need to update the ECU, but if you already have the new valves then no updating of the automatic gearbox ECU is required.

These are the valves, found on this topic 'Dropping back into 3rd at 45mph'

HI,
As I have just changed the valves on an 04 plate c3 1.4
I would say there is a very good chance that you have the later valves fitted ie. black connector.
Therefor changing is straightforward and no software updates are required.
regards.
