What is Fuel Injector “Black Death”?

What is the dreaded “Black Death” that many sprinter van owners have come to know? How do you know if your vehicle is affected? What can you do to repair and prevent it? The Black Death is a mechanical issue involving your vehicles fuel injectors and more specifically their seals. This problem is given its name due to the thick black residue found underneath the plastic injector cover. This black residue is a buildup of carbon as a result of a leaking fuel injector. These leaks can arise from a few different causes including; faulty injector seals, improperly installed seals, or incorrect seals being installed. So how can you tell if your van is having this issue? There are a few red flags that show when it comes to Black Death that you can look out for including; rattling sounds from the engine, hissing or leaking sounds from the engine, failure to start, and obviously removing the cover and checking for the black residue carbon buildups. So your van has the “Black Death”, it’s not the end of the world, there are a few steps you can take to fix your leaking injector and restore your engine back to its originality.

The first thing you should do is remove your leaking injector. (You’ll see the white mist escaping the injector when running). To do this disconnect the fuel line to the injector, disconnect the wires to the injector, remove the injector bolt, and use one or two screw drivers to pry the injector from its seat. (This takes time, be patient and do not use too much force in risk of breaking the injector). Once the injector is out, determine whether or not the entire injector or just the seal needs to be replaced based on exterior wear.

Side Note – Once you remove the injector bolt you MUST purchase a new one to replace, these are only meant to be installed once and cannot be reinstalled. Once you finish with the cleanup process, follow the steps on removing the injector in reverse order. After replaced, make sure to properly torque down the bolt to the correct specification and clean off the rest of the carbon buildup.

Resetting the Mercedes Sprinter Van Service Warning Light

Resetting the Mercedes Sprinter Van Service Warning Light

Having issues with any of your vehicle’s function could be a total discouragement especially when you are dealing with expensive transports like the Mercedes Sprinter. But did you know that this van has an onboard diagnostic system that traces failures? This unique feature triggers a “Service Soon” light that appears on the Sprinter’s dashboard when the vehicle needs to be serviced. One great innovation of Mercedes is that it doesn’t require special tools to reset the warning light. However, you need to do the work yourself or have it serviced before you can manually reset and turn-off the van’s warning light.

Here are the steps:

  • Insert the key into the ignition and turn it to the “ON” position, but don’t start the engine yet. Search for the tachometer and speedometer displays on the instrument panel.
  • At the lower left part of the steering wheel, press the button. The display panel will show why the vehicle needs servicing.
  • On the left side of the instrument panel, find and press the reset button. Hold the button for three seconds before releasing it.
  • Press the reset button the second time and hold it until the display will show that it has been reset. Turn off the vehicle and wait for 60 seconds.
  • Switch on the engine and confirm that the service light has turned off.
