Common Problems
The C123EF0 fault code often shows up in Audi vehicles. When this happens, the ABS warning light turns on. The traction control light may also appear at the same time. Drivers usually see an error message that says: ‘Brake system fault stop carefully.’
This fault stops the ABS system from working, which means emergency braking is no longer available. Because of this, the car relies only on standard braking. This increases safety risks, especially during emergencies or in bad weather. Fixing the issue quickly ensures the car stays safe to drive and avoids further problems.
