Iâve learnt to live with it, but it is annoying. My brake pad warning lights stay on, despite the brake pads being fine. This is confirmed by Audi and this is on my : Audi A4 Avant S Line SE, 56 plate (Sept 2006). As it happens it did start occurring after a service at Audi (about 2 weeks) Audi have quoted about £400 or something to fix it, but this is too much. Anyone else had this and know of a cheaper fix?
