If your Mercedes-Benz is showing warning lights or a system has stopped working, the fuel pump control module is a likely suspect. This guide explains what the part does, the signs of failure, how to choose the right OEM replacement and what to expect after fitting.
Mercedes-Benz models use networked electronics across the whole car, so one failed module can trigger several warnings at once. We currently list 1 Mercedes-Benz fuel pump control module option from $56.05.
What the Mercedes-Benz Fuel Pump Control Module does
The fuel pump control module regulates fuel pump output to hold the correct fuel pressure. When it fails, the related system can behave unpredictably or stop completely, so a correct OEM replacement restores original operation.
