hi just wondering if anyone can help me. abs light is on so ive scanned it with my code reader and got 00285 which is front right abs sensor. does anyone know if it is likely to be the sensor its self that needs replacing or if it is the abs ring? I recently had to have a new abs ring on the rear right due to the old 1 being badly corroded, so im guessing that it is a similar problem. any help will be appreciated.
