Audi 5000 CD turbo - brake problem !
 

This audi is 15 years old, now if I applied the brakes, the dash board will beep four times, along with the red light in the center ( with exclamation mark ) blinking 4 times, then 4 more times without the beeps.

Any ideas ? On board diagnostic computer reports code 4 4 4 4, which indicates everything is fine.
Thanks guys.

Bill.

William,
The brake problems will not show up as an error on the ECU (checked with the fuse in the fuel pump slot). It sounds like you the pressure accumulator (aka - "bomb") is failing. See:
