Hi

I think that the eml has to be reset with tech2 or after a number of clear starts.

Hope that this helps. By the way how dose the car run.  :question

Hope it's not a daft question, but are you sure you're looking at the EML (orange) and not say the (red) air bag warning light?
EML usually accompanies poor running symptoms.

Disconnecting battery will have no effect on these ECUs.

If the light is on the ecu is not happy about something so it's worth finding out what.

You need to sort why its coming on - if it is emissions related, it may damage cat if left unchecked.  Or it may break down unexpectedly.

Try paperclip test first - free, easy, and quick :y
