i dont think it will be error free on the astra j 5 door DRL as they are on the cambus
the astra GTC is not on the canbus so they do not need load resisters to cancel the errors
if they have a LED that works error free on the corsa D then it may just be like the astra GTC
and not be on the canbus the LED bulb may well work on the astra j 5 door and dim etc
but i would be 100% sure loads would still need to be added
