if it is the light that looks like a heart monitor that has started on my car as well (megane 1.6e 1996) it could be that on the left hand side of the fuse box there is a box where thefault diagnostic machine plugs into is the lid is opened there i presume this is a tameper light to tell the dealer that the vehcle has tampered with this should be no problem (exept the anoiance) just take it to renault or a garage with the computer to fit a rebnault and have them wipe the error codes that'll sort it
