The back brake lights are out on my 03 1.9tdi A4 aand these warning lights are flashing.
I first tried changing the bulbs. No joy, so I had a look at the fuse and it looked fine.
I had a read about and a lot of people were saying it's the brake light switch, but the funny thing is my center brake light still works!
I rang Audi and they confirmed that all 3 brake lights work off the same brake switch.
I'm a bit baffled now, any ideas??
