Immobilizer. Nothing works anymore, no ignition, no start, no tow

My problem child is a Phaeton V8 first registration 2013, 140TKM. Now my problem. My partner is shopping with the fat one. (Always take the bowl with you when you are on holiday.) When she wants to start again : steering blocked, workshop. As Whats app contact between Egypt and Germany. Ace comes to bring the car home. Since the choice lever can not be moved the next day 2 start with lifting glasses and rollies. Car finally home. From the holiday the matter visited n A little while ago I read in Africa. Error memory by means of VCDS tries to read out but also with light horn switch position I do not come into all ECUs. No cable break of the 3 wires at the steering column. Both batteries full. Both batteries are jammed. And now it is strange. Car Keyless unlocks, radio runs display shows driver door open. Normal door is open. Interior lighting front lights as desired, reading lights do not. On start attempts with key 1 or 2 or Keyless NOTHING. Display no longer shows anything. Carpet is dry. In the change the display sometimes shows: Steering Blocked Whether doors are open, everything is right. Nothing at all. Leave comfort battery on the 30A charger and start battery on the 6A charger tonight. Does anyone have an idea? If everything doesn’t work out. How is the easiest way to deactivate the parking lockThen he goes to Zottel
