I have a very strange phenomenon at my 99 v70 Lpt. The left abs sensor is new, ABS ECU has been repaired by a company 3 weeks ago. The abs/tracs and motor light are from which were previously with the defective abs control unit on the light. That’s already a positive effect, only sets no matter at what speed when driving !!!! And also when braking the abs constantly. So a ride is of course not really good and especially dangerous, what could that still be? More sensors or wreaths to deposit without a mistake? Has been read out in this regard several times at Volvo and the ABS light stays out too. Hope you have an idea
