Was the dealer able to vefify that the master cylinder is in fact defective, just not a bad sensor? Or, are they, like many auto repair shops, "shotgunning it", replacing everything that it could possibly be just to avoid a call-back? Is the master cylinder leaking? Have you felt anything strange with the brake pedal? Have you tried clearing the error code to see if it comes back? I would sure hate to shell out $2000 for a new master cylinder and have the code come back later for something simple, like a low 12 volt battery or super capacitor issue.
If they can guarantee its the master cylinder, I'd be shopping on car-part.com for a replacement from a yard. I see them as cheap as $450.
