Espace MK3 Airbag ECU

Hi



I've got the airbag error light on the dashboard. I've followed the guide here, but it's still present.

I located the airbag ECU under the centre console.

Here's the label .

My question is does anyone know which number I have to search by to order a replacement. Searching for the Matra 6025313596 number finds results, but the last part of the 'breed' number is different.

Is the breed number important?





Thanks
