I'm pretty sure it will not help.
But you can try.
with card out of the reader and everything off.
Put the CD into CD reader.
It should accept it.
then put the renault card into card reader to the end (don't start the engine) and wait.....
if update is not shown on the sreeen then it will not work...
Do you sudgest anything else after that, Have checked all fuses, Tried the reboot sequence and still no joy
