how to disconnect an immobilizer on Peugeot 406 TD Wreg?

I have had this to two garages including one specifically for French cars but no luck. It is indicating an immobilizer fault on the dash light. Engine turns over, lights work, horn,windscreen wipers and door locks. Tried all the different ways to reset the key, all the fuses are OK including connection in the drivers foot well but to no avail. When the diagnostic machine is connected to the ecu the display is blank. I am hoping to be able to bypass the immobilizer if anyone knows how to to do this.
Thank you

hi had this afew times now and how i get a round this is on diesel the way they stop it from starting is to stop the power going to the mag valve so no fuel so now u understand how it works . now how i do it ,a , add a live wire to the mag valve to make it open by so fuel can run but if u cant make that work then take the mag valve out there is a spring and small black like rubber now just take out those two bit s pop mag valve back in and it will run as there is,nt any thing to stop it from going but the only prob is that way it will not stop off the key u have to pop in gear and foot on brake that will stop it . now only use this till u get yourself sorted out with the real prob .as y i,m having to tell u this .best of luck o yes mag valve is on ur fuel pump
