Mercedes-Benz Sprinter Transmission

Automatic transmissions are the backbone of your Mercedes-Benz Sprinter, allowing your transmission's gears to produce the correct amount of torque based on driving speed. Without it, shifts in speed would be virtually impossible and cause premature wear and tear on your engine due to consistently high RPMs.

Other issues related to automatic transmission problems on your Mercedes-Benz Sprinter include sluggish acceleration, excessive gear slipping, and stalling, especially when climbing uphill. Here are some of the most common transmission issues to look out for:

  • Leaking transmission fluid could mean a puncture in the pan or loose plugs
  • Burning smell from your transmission could indicate low fluid levels.
  • Engine overheating could be a problem with your oil cooler hose not regulating temperature like it should
  • Check engine light turning on could signify a larger problem a technician would have to diagnose

In any case, if these issues are not addressed quickly it could lead to dangerous driving conditions and cause further, more expensive problems down the road. Read our article to get more information about these issues and how to spot them and fix them from our Mercedes-Benz Sprinter Transmission Repair Article.


Mercedes-Benz Sprinter Door Locks

Your Mercedes-Benz Sprinter's door lock is unassuming but consists of complex mechanisms with tight, interwoven parts. More commonly referred to as door lock actuators, lock actuators use an electric motor to control a rack and pinion gear set responsible for releasing and securing the lock.

If there is an issue with a door lock actuator, the likelihood of replacing the entire latch assembly is very high. Some common problems people will have with the doors are:

  • Power door locks do not activate
  • Odd noises from inside the door

If you experience any of these issues, read our Mercedes-Benz Sprinter Door Lock Repair Guide to learn how to troubleshoot and fix the issues.


Mercedes-Benz Sprinter ERG Valve

Your Mercedes-Benz Sprinter's exhaust gas recirculation valve (EGR) is an integral part of your exhaust gas system. It is responsible for reducing NOx emissions by recirculating exhaust gasses back into your vehicle's intake manifold. Think of it as a manager of exhaust gas flow. It is located in your vehicle's engine compartment and is controlled by your engine control module (ECM), which uses sensors to monitor the EGRs output while driving.

From time to time, your Mercedes-Benz Sprinter's EGR valve could malfunction due to clogging or all-out malfunction due to heavy wear and tear. Specifically, excessive carbon deposits, debris, dirt, and soot could accumulate in your EGR valve, causing it to remain stuck. This is especially true with urban driving. Here are some signs to look out for that could mean your ERG needs replacing:

  • Sudden loss of power
  • Knocking sounds from the engine
  • The check engine light turns on

In any case, if you suspect a malfunctioning ERG Valve, you may have to test it to see if it still works. Learn how to test your ERG Valve and the steps to take to replace it in our Mercedes-Benz Sprinter ERG Valve Repair Guide.


Mercedes-Benz Sprinter Fuel System

Your Mercedes-Benz Sprinter's fuel system is its lifeblood, responsible for delivering fuel from your tank to your engine. It comprises a fuel tank, fuel pump, fuel filter, and fuel injectors - all performing in tandem to manage a combustion process that mixes fuel with air before being ignited and made into the exhaust.

In a nutshell, your fuel pump sends fuel from the gas tank to the engine. In between, fuel navigates through the fuel lines in your vehicle's undercarriage, bypassing a fuel filter that grinds out dirt, debris, and other contaminants. Once fuel bypasses your fuel filter, it travels to the engine to rev up your piston and gears.

On occasion, heavy wear and tear and extended driving can compromise your fuel system.

Learn how to spot, and fix common issues with parts associates with your Sprinter's fuel system, including your fuel pump and fuel injector, from our two guides:

A loss of power is a good sign that you need to look into your turbocharger. Remember new diesel equipped Mercedes-Benz Sprinter turbos may turn off based on EPA emissions, which causes it to lose power. This is also referred to as "limp mode." Read more about how to troubleshoot and fix your turbo problems in our Mercedes-Benz Sprinter Turbo Repair Guide.


Mercedes-Benz Sprinter ABS Sensor

Your Mercedes-Benz Sprinter's wheel speed sensor, also known as the ABS sensor, is the electrical connection between your wheels and braking system. A sensor passes axle speed data back to your braking system. This, in turn, helps manage the amount of pressure placed on the axle to prevent damage or stop the car too abruptly or slowly. This process usually starts once a wheel speed sensor reads travel speeds anywhere between three and five miles per hour.

In addition to recording wheel speed, wheel speed sensors interact with anti-lock braking systems and traction control mechanisms. Here are some things to look out for that are signs your ABS sensor needs to be replaced or fixed:

  • ABS light comes on on the dashboard
  • Front tires locking up

Our Mercedes-Benz Sprinter ABS Repair Guide goes over these problems and provides steps to fixing the problems.
