The minute my car’s dashboard gone mad!

I was on the fast lane near Bagatelle, driving towards Port Louis when suddenly, all the readings on the dashboard dropped to 0 (the speedometer, the fuel tank reading, the temperature and the motor revolution)! I immediately took the left-most lane and parked. After giving a few calls, I drove again and upon ignition of the engine, the speedometer showed 80km/hr, the revolution ~3 while tank read null. I drove carefully back home, and here is a shot, while I was IN MY GARAGE!
