I have a problem with my rear lighting as I have recently started getting error messages on start up saying 'Rear light left and rear light right failure', all lights are however working fine, I tried to clear the faults with my Carly but the error remains. Any ideas folks ?... thanks.

Any sign of water ingress or corrosion at the connectors?  That would trigger a high resistance and that can trigger a lights out warning.  Both are known problems on early E70s.  BMW eventually redesigned the seals.

Oh and to the Forum
