The warning “Brake system fault: Stop carefully” is a common issue in Audi A4 models (B8 and B9 generations). This fault disables the ABS emergency braking, leaving only standard braking available.
The ABS pump and module often store the fault code C123EF0 - Hydraulic Brake Booster Limit Value Reached, causing the ABS warning light to stay on. Many owners are told to replace the ABS pump at a high cost.
At Frost Cars Electronics, we offer a better solution: test and rebuild your existing ABS pump and module without needing re-coding.
