You have an electrical problem mate...get it sorted. It should go on with the battery light when key is in ignition then go off when you start it up. I'm not saying owt about renaults. I love mine but my ABS has just gone tempermental so......
you in the AA? Call em out and get them to clear the light or tell you the problem...is it running on all cylinders? If not a coil problem is likely...a lot of these lights are also coz of are faulty sensors and not big bucks if you know what is wrong vbefore the garage!!
