hi i am hoping that someone can answer a question regarding the abs system on a 2004 laguna 1.9 dci. i have read many threads on here but am still no wiser as i have replaced sensors and electrically checked the wiring to the sensors with no apparent faults. i am now thinking do i have a problem with the abs ring on one of the wheels. however i am been told that there are no rings on these cars and i need to replace the complete driveshaft as its attached to that, find that hard to believe. I have the usual abs and service light on the dash which was intermittent until yesterday and its on all the time now. does anyone know if the rings can be replaced or not? thanks in advance.
