Hey just looking for some insight,
I have a b6 s4 and recently I got a left brake light warning, followed by the right brake light warning shortly after.
I changed both bulbs with the dual filament, 7528 I believe, to no avail. I did clean both sockets, and made sure the contact point was not bent/damaged.
I did search a few forums for a fix, and saw some people had a problem with their brake light switch. I'm not sure if it is considering my third brake light works perfectly, and I don't have the Esp light come on.
Any help is appreciated,
