Suzuki Swift 1.2 year 2013/ESP problem

Hello in the round , Have a problem with my Suzuki Swift 1.2 with 94 HP Built November 2013 . I bought it also at that time new . Have for some time the indicator lamp ESP on . But is also sporadic from time to time … So if you turn on the car lights up nothing , after two or three minutes it goes on again during the ride . Sunday … have looked the front sensors and made a view control everything ok . After that also the butt sensors have checked after and also from CHRAUBT. Were only a little wet , had cleaned the naturally dry . After that Sunday all the time , the lamp did not show up any more . Monday after work back , lighted again . Was also in a workshop having conducted diagnosis apparently ABS sensor ( ECU ) . That can not be … I’m really desperate . Would I be happy for any helpful answer from you Thank you in advance
