Check for parasitic draw on the battery.

I have done a parasitic check and everything is normal,and the problem is not a constant one it comes and goes,and all last week the car was fine,yesterday after being out i came home and parked it as normal,went outside after about 2 hours and was still fine,then suddenly whilst out by the car the indicators just started flashing again for no reason and the alarm was not sounding,just all hazard lights flashing twice in a constant rhythm any ideas if this could mean getting a new immobilizer module

What did you scan it with?
In my experience with All French cars only the manufactures own diagnostics give clear and accurate results.
In this case it'd be Renault Can Clip.
Though Bosch KTS will undoubtedly work as well.
Others give unclear or even false results.
