have you had your abs checked with a diagnostic scanner? You may have to take it to a service repair center to do this but the abs has a brain that you can hook into. A qualified service tech should be able to tell you if you have any trouble codes or if a sensor has gone bad. If the guy you took your car to didnt do a diagnostic scan before telling you what he did then he is either an IDIOT who shouldnt be working on cars, or He is a scammer who wants to charge you money so he can learn whats wrong by thowing parts at it until its fixed. Do a diagnostic scan on your abs and see what its doing! |
