I have a VW Passat 2.0 SE 2003 ,I have a abs and eps light staying on, I checked and i had no brake lights, so i changed the brake light switch and now have brake lights, after restarting the abs and eps light stayed off for a short while then came back on. but this time i still have brake lights, would the fault codes still remain if the fault is rectified? do the fault codes need to be cleared, and if so how can you clear them without the VAG-COM
