Help! Electrical fault

Dear all,

I have an octavia Elegance 05. Recently I got a weird problem with the car. Most of the warning lights from the dash board came up and when I tried to stop the engine, this didnt stop even, when i took the key out and lock the doors.

I took it to the garage and they stall it to stop it. they could not look at it at the moment so they leave it for next day. Next day everything was ok and none of the lights were coming up.

But after a month, I have the same problem.

Any ideas?
