VW Phaeton V 8 short circuit in the system – No current – Nothing works anymore

Hello to all, here is my short description, which happened to me on the weekend. Friday NM( 10.11.2017) I put my VW-Phaeton at lunchtime. In the evening, a hotel employee followed me that the light is still burning and the radio is on. I had the vehicle as always with the remote control closed and everything was off??? I wanted to open the car in the evening, however, this only worked manually with the key. In doing so, the alarm system triggered. I put the ignition key in the ignition lock, but also this attempt failed to turn off the alarm system. On Saturday morning(11.11.2017) the hotel staff tried to give me start assistance – but this failed. As a result, I called the ADAC, the employee did not fix a light fire odour.
