How to diagnose Mercedes Misfire Problems
mercedes benz fault codesMany mechanics and car owners donít like to work on Mercedes because they believe that MB cars are difficult to diagnose due to the large sensors and electronics. In our opinion, if you have the proper tools diagnosing Mercedes cars is easy. Luckily for you, the misfire codes are stored in the ECU and are very easy (and inexpensive) to retrieve. To diagnose an engine misfire on a Mercedes all you need is a generic OBD II code reader that can be bought in some cases for under 20 at your local auto parts store or on Amazonís Best Selling OBD II scanners list. If you would rather invest in an advanced OBD II scanner for Mercedes, then read our article on Top 10 Best Diagnostic Scanners for Mercedes Benz.
