Not knowing how serious the problem is, you cut your drive short and avoid going back out on the roads until you can take your car to the service center. The check engine light is just the most visible part of an essential and complicated system known as an OBD On-Board Diagnostic system. An OBD system is a computer in your car that combines data from dozens of sensors throughout the vehicle to identify any problems. This code tells you what the specific problem is with your car. Here are a few of the most common Mercedes fault codes that tend to arise and ideas on how to address the issues they reveal. The mass air flow MAF sensor monitors the ratio of gasoline to air flowing into your engine. Keeping this ratio consistent and accurate is vital to ensuring the performance of your car.

Mercedes builds some of the most advanced vehicles on the road. To keep everything running smoothly, Mercedes' onboard computers monitor hundreds of individual systems, sensors and variables and make corrections as necessary to optimize performance, shifting, braking, traction, stability, safety and other vehicle parameters. When anything goes wrong, your Mercedes registers the error or deviation and produces a fault code. You should always take these warning lights on your dash seriously and immediately bring your car or sprinter to a Mercedes specialist repair shop such as Burdi Motorworks here in Chicago whenever a warning light comes on. In some cases, there might be a simple fix such as correcting a low fluid level, tightening your gas cap or cleaning a sensor , while in other cases your Mercedes may require additional service or repairs. In newer Mercedes models, the fault code will trigger a dash light or error message, alerting you to get your Mercedes inspected and diagnosed. Thanks to the error codes recorded by your onboard computer, our trained technicians can quickly determine what is wrong. When you bring your vehicle to us, we start by hooking our diagnostic equipment up to your ODB-II port and reading all registered error codes. While all automakers use a common language for error codes, each one has specific definitions. That's where our experience with Mercedes Benz vehicles and our advanced diagnostics equipment is critical. Our experienced technicians can read all of your error codes both current and previous and plan the necessary service to get your Mercedes running perfectly again. We can also reset error codes and see if they come on again, which can be a sign that a temporary problem has been fixed such as low oil, bad gas or dirty sensors or that a problem is intermittent and appears again after a short time. All of this error code information points us to the root cause of your Mercedes issues and guides us to the right repairs.

Mercedes-Benz automobiles are among the most cutting-edge on the market. Basically, this means that if anything goes wrong with your car, your car will be on top of it by coming up with fault codes. In the past, if anything went wrong with your car, a trained mechanic would rely almost entirely on guesswork to resolve the problem. This was a painstakingly long process that involved taking components apart, testing them individually, and putting them back together before testing another possibly faulty part. Nowadays, mechanics use scanners that plug into a modern vehicle to get fault code readings. A fault code is a series of letters and numbers that describe a very particular problem in a car. Fault codes differ from ordinary malfunction indicator lamps or MILs engine temperature, battery warning, oil pressure, brakes, etc. Each DTC will contain 5 characters with at least 1 letter, with the first character always being a letter. These letters refer specifically to hybrid propulsion systems.
