Try posting in the B7 forum, not everyone reads the sub forums.
I had to replace one of the plastic enclosures that the ECU sits in as it was letting in water.
Best have a look to see if you can see any moisture ingress and/or damaged wiring as the looms can get brittle with age.

How old is your battery ? Worth checking that and brake light switch.? These two are known to cause the light to come on .

I already have posted in B7 forum but no replies, and checked the enclosures, no moisture also checked the ECU connectors etc. Looks fine...
