When Your Mercedes Sprinter Loses Power

Mercedes Sprinter van owners choose their vehicles because of the impressive mix of power, reliability and fuel economy. If any of the sophisticated control systems on the vehicle are malfunctioning, you can have issues with starting, idling or driving your Sprinter. In many cases, these problems will get worse until the van won't start at all or you suffer a major failure that requires a serious overhaul to repair.

Recognizing Power Loss Issues

Knowing how to troubleshoot some common cause of your Sprinter van losing power allows you to contact a qualified Mercedes shop before they become major issues and have them fixed. Watch for power loss issues related to:

  • Turbo lag: This is when there is a lag between the moment you start to accelerate and the moment the turbo kicks in to deliver full power, acceleration and pulling power.
  • Loss of power: If there is a problem with your engine, your Sprinter can go into ‘limp home' mode — your engine control unit limits the power of your engine to avoid damage.
  • Turbo failing to come on: In certain cases, your turbo may not come on at all, representing a significant reduction in engine power. Restarting your van may temporarily correct this.

You may also see issues related to idle speed/roughness, throttle responsiveness, fuel consumption and tailpipe emissions that are causing a loss of power.

Troubleshooting Your Problems

Once you've detected power loss problems, it's time to look at some common causes to understand what is going wrong. There are some points that you can look at under your hood to determine what is causing your power loss. Check out our list of troubleshooting points to consider:

  • Check the condition of your air filter
  • Verify that your air filter hose is well secured and not cracked or broken
  • Verify that the Mass Air Sensor is properly connected

  • Look for evidence of soot or strong fuel odors at your tailpipe
