I bought a lagoon that did not work ABS and ESP connected to the computer showed error DF017. I checked the ankle contacts at the pump, the power supply on both red wires was and - on both black ones. I deleted the error several times with the DDT2000 program and with 4 or 5 together the error disappeared but the indicator light came on after about 40 seconds and another time after firing the error did not jump out immediately and after driving about 1 km. What could it be?
