I had a brake problem on the day, taking my EG6 VTI , for MOT & Service. Main dealer said front brakes not working , they removed the ABS Modulator and sent it for Repair & test. The Repair Service have checked and have sent ABS Unit back to Main dealer. Service team say, they will fit ABS Unit back into the EG6 and do some tests. Anyone have an idea of correct diagnosis please .
