Hi peeps im new here, the other half has a late 04 reg "astra g" 1.6 twinport sxi...
Some mornings when cold the yellow spanner light comes on, if you turn off and turn back on it stays off for the rest of the day
I have had it on diag and it says "P1131 - port de-activation due to low voltage"
does anyone know wtf this means. many thanks
