Daewoo Kalos SX Blinks for no reason and on your own!

Hello! We have a Daewoo Kalso SX 5 doorr. is 6 years and has 120.000km on it Already again and again we have noticed that He has no reason Be it in the garage or outside sometimes starts to flash. This had not bothered us because when you get back up and to make the spit again for weeks is over. But unfortunately stand that car is now due to illness a week in the garage and had continuously flashed until the battery empty what we ourselves did it only afterwards from the Neighbor who after I removed the battery to charge has approached me and asked if the battery is empty because of flashing since he observed for a week (but it didn’t tell us grrrr….) Now the battery has been full again and my wife was today after work a little on the road where the kalos has started to blink again several times. (once in a public parking lot / outside and once in the garage) The car has according to description no Alarm system… a workshop visit a few years ago was unsuccessful… because we don’t want to get back into the situation that the battery is empty Farge I’m here with you once where the reason might be in it and even better if you could solve that problem Dear Greetings CoolCopper
