Hello there! I'm Eurocar ! I will try to assist you as much as I can. Quality research = Quality answer!!
a scan tool can only clear the faults
usually if the dealer has cleared the roof fault and the indicator comes back on then there is still a fault with the system
a scan of the modules are needed
please also check the battery again i have seen at times that the contacts of the battery of the remote is poor and can cause the light to remain on.
please try to make better contact with the battery at the remote side and recheck
please lket me know
I already new the info you provided please provide a more detail. It is not unusal for the roof indicator to display false indication, I am looking for away to eliminate going to the dealer. The above is not a reasonable response to my question.
