Is the car running ok? That relay it refers to is the relay 109, that's the main power for the ecu. I think terminal 30 is something to do with the battery and central electrics or some such thing. Anyway from what I could find it's worth cleaning the battery terminals and earths etc and maybe try a new 109 relay for good measure.

The car is running fine - higher chance of the lamp coming on when cold, I assumed it was to do with the heater plug loom or similar.
