I recently had my turn signal fluid replaced in my Audi A4 and wanted to know what type of fluid was used. Can anyone provide me with this technical information?
ReplyThe turn signal fluid for an Audi A4 is actually just regular brake fluid. So as long as you are using high quality brake fluid, your turn signals should function properly.
I'm not too sure what the official turn signal fluid for an Audi A4 is, but I've been using DOT 3 brake fluid for years and have never had any issues. Just make sure to check your car's manual to confirm compatibility.
