Recenty with my car I've noticed that the AFS Off light is constanty binking on and off regardless of whether its day or night or anything. it just never stops flasshing while I am in my vehicle, When I try to press the button that turns it off it stops for 5-10 seconds then comes back on right after. I apologize for my lack of knowledge n this but this issue has really been grinding at me I hope its not something too serious and any answer wuld grealt be appreciated. Thank you for youe time.
