This is correct after another hour or so swearing and screaming last night I still didn't manage to find the vss... it doesn't have one despite the garage saying that's what I need and the part being on the system under the reg!
So the next question is with diagnostics code c1155 N/S ABS wheel speed sensor.. should I just jump to buying the sensor and fitting it or is there any other investigations I can do to check the faults origin?
