ESP lamp burns permanently

Hello all, I bought yesterday a used Kia Ceed SW 1.6 gasoline, 125hp. EZ is 03/2010, KM-Stand 61100. After completion of the purchase and transfer the ESP light (not ESP off!) went on permanently after about 15min. Beautiful shei*e! At the test drive the light was not on. Here is a photo. When I restart the car, the light is off again. This morning it went on again after about 20 min. Is this a known problem if necessary? What would be like a worst-case scenario If there’s something seriously broken, there’s a malfunction in the manual – that can be all… Thank you, many regards Mario
