Hi guys

My abs light is on since yesterday. But when i restart the engine the abs light is off and will on back at random time while driving.

So warranty already over many months ago, i clean the abs sensor myself ( it is not much dirt anyway) . I drive to test the car and abs light still on. But this time I try to jam the brake all the way and car never skids ( i did for 3 times to confirm ) which means abs still work while the light is on .

So i scan my obd reader and these 3 fault codes comes out

U1017 - no data online, maybe it is Proton specific code, most likely is the ABS code
P005E - Boost controller low voltage ( thats explain my sky high fc, 13.2l/100km ) 
P1401 - Exhaust Gas Recirculation (EGR) valve
