Hi thank you for all your help so far.
I can confirm that there is a 15amp fuse in fuse 3 ,i have changed the ecu and the 5as unit and the volumetric sensor .the problem remains the same.you can program the fobs ok but they will not open the doors and no alarm light is present.The car runs and starts straight away.
with the new ecu fitted the alarm light came on briefly and then went out.I have not been able to make it come on again.
what can be wrong ?????
