Scenic 1 Electronics problems

Hello, the following problem: This morning the car started quite normally, 500 meters driven, turned off. after that the car did not want to start any more. I started it by rolling then. Here the stop lamp and oil can approached. Having arrived at home, the car did not want to start any more. Thought, battery empty. I then tried by starting aid, started only after a few attempts, then not again. Thought ok, battery down, had another built-in, the same problem. After a few times per bieren, starts the car now. But: there are no blinkers when I activate windshield wipers, at the time where the wipes, the lamps stop and can go off and it clicks in the fuse box. Sporadic the WARBlinker system turns on. What can I do? Help, it is Sunday, no workshop accessible, the car must drive on Monday((((
