The ESP/ABS lights are on in my 2005 audi a6 3.2L Q. I've tried replacing the brake light switch but the problem remains.

Do these codes/lights usually mean the ABS Module needs to be repaired or could is simply be the brake pressure sensor?

Sounds like the ABS module. The same ESP/ABS lights popped up in the B5's when it was proven to be an ABS module. I know that there are places online that can repair your module without too much cost.

Brake pressure sensor G201 is inside ABS module/hydraulic assembly. The only repair i know so far is replacing the assembly.
