Common Problems
The C123EF0 fault code often happens in Audi vehicles. When this issue occurs, the ABS warning light turns on, and the traction control light may also activate. Drivers often see the error message: ‘Brake system fault stop carefully.’
This problem disables the ABS system, which means emergency braking is no longer available. As a result, the car relies only on standard braking. This increases risks, especially in bad weather or during emergencies. Fixing the issue quickly keeps the car safe to drive and prevents further problems.
