Brake Pad Wear Light

On my 1990 Audi 100, I got a similar problem, but it's due to the wire being 
"kinked" near the pad , so short of replacing the pads, there's nothing I 
can do about it...

1990 Audi 100 - 347,000 miles
1990 Audi Coupe Quattro - 69,000 miles
2003 Audi A6 Avant - 69,000 (gee, 2 cars with 69K miles, yet years apart!).

I haven’t seen a response, so I’ll give you a fading 10-year-old memory. 
That light comes one when the brake pad is worn so much that it wears 
through the wire in the pads, breaking the circuit and lighting the warning 

If you only have 10K miles on the pads, then there is probably a break 
within the circuit (IIRC, which goes from under the dash, to the left front 
pad, the right front pad, and back to dash). You can try to trace the wires 
(pick a pad and check along both wires). But, and things are hazy here, 
those wires go back to a relay or a junction box before heading to the light 
in the dash. You can make a jumper wire to insert into that relay connector 
or junction box, to bypass the whole mess, ensuring a continuous circuit and 
no warning light.

Don’t ask me where or how to jump the connection. You should be able to 
search the archives for that.

Good luck.
