both front window's won't work. When I press the button nothing happens. No motor sound, no slight window movement. I've checked with a Electrical Light Screwdriver to see if I have power at the button and the multiplug's connecting to the window motor, which I do.

I really doubt that both front motors have gone at the same time.

The Car does have a new ecu if that can make any difference.

Any help?

Engine ECU (engine bay) or BSI (glove box)?

The BSI controls the electric windows, so this may not be configured if it as the BSI that was changed.

It ain't a brand new ecu, my old one suffered from water damage so it was sent away for repairs. I'm not sure what what they did but I know it's the same outer shell. When I first got it back the passanger window worked fine (not driver) but now neither work. Everything else works fine

It was the engine ECU that was repaired, not the glovebox one

The engine ECU has no connection to the electric windows, so I guess that you problem is not with the new Engine ECU.

It would be worth checking the plugs on the BSI are connected correctly - maybe just disconnect them and reconnect them. I am not sure which plug is the one for electric windows on the pluriel, if you added a picture of your BSI dropped down it may help to identify the one fitted.

This is interesting, but unconnected to you window fault, how did the engine ECU get water damage? They are very well protected under the battery cover.... but obviously not well enough :D

The auto electrical guy who came out said it's common on C3's for them to leak from the thermostat down the cable and into the ecu multiplug, not sure if that's true but it looked damaged.

This is the BSI I have.

Yes, I have seen it come up before somewhere and appears on a peugeot site here where the coolant leaks into the engine ECU.

I had a look but can't find the wiring plugs for that one. Sorry. It ill be a case of checking each multiplug. Disconnect and reconnect once you have sussed out how to disengage the plug from the socket.
