What is the issue with the Mercedes-Benz C48V fault?
2 Answers
Mercedes-Benz C48V fault refers to the electrical equipment losing its original function, including mechanical damage of the electrical equipment, burnout, breakdown of electronic components, aging, performance degradation, etc. Taking the 2021 Mercedes-Benz C200L as an example, it is a mid-size car with body dimensions of: length 4784mm, width 1810mm, height 1457mm, wheelbase 2920mm, and a fuel tank capacity of 66L. The 2021 Mercedes-Benz C200L is equipped with a 1.5T turbocharged engine, delivering a maximum horsepower of 156PS, maximum torque of 250Nm, and maximum power of 115kW.
Last time I encountered a 48-volt system issue with my Mercedes-Benz C-Class, it was quite a headache. That 48-volt system mainly handles auxiliary starting and energy recovery. If it malfunctions, the car may have difficulty starting, the dashboard warning light may illuminate, and the driving experience may feel underpowered. Possible causes include an aging battery or loose circuit connections—if the battery deteriorates, it can't hold a charge. I recommend not attempting DIY fixes, as 48 volts is unsafe and poses an electrocution risk. It's best to visit a 4S shop or professional repair facility promptly for diagnosis. They can use a computer to read fault codes and pinpoint the exact issue, such as whether the battery is leaking or the control module needs replacement. In daily use, avoid leaving the car parked for extended periods to prevent battery drain. During maintenance, remind technicians to test the system's condition as a preventive measure.
