Mercedes C-Class W204 ABS Pump Problems

The Mercedes C-Class W204 ABS pump and module commonly experience failures that can lead to various issues in the vehicle. These failures can impede the emergency braking system and result in a lack of power steering assistance, making the vehicle challenging to drive and potentially dangerous in emergencies. Warning lights such as ABS, ESP, ‘Power steering malfunction,’ and ‘Run Flat Indicator inoperative’ may appear on the instrument cluster.

When diagnosing the problem with scan tools, fault codes like 5001, 5944, and 5945 for control unit N30/4 ABS internal faults are often found.

While a common solution is ordering a new ABS unit from the manufacturer, this can be expensive and may require additional costs for SCN coding or adaptations. An alternative and cost-effective solution is ABS module, pump, and motor repair.

Our repair service involves testing and rebuilding the ABS pump and module, eliminating faults to prevent their recurrence. We use high-quality replacement components, and the process retains all necessary coding information. The turnaround time for the repair is typically 2-3 working days.
