About the E-Class
The executive E-Class officially entered the market with a name change in 1993, but its roots can be traced back to 1953. Since then, there have been a total of five generations to be released. The latest iteration made its debut in 2016.
The model has been offered in both a 4-door sedan and 5-door station wagon layout for a number of years. There have also been coupe and convertible variants.
There has been some speculation regarding the release of the sixth-generation model. With any luck, the latest version will make its debut before 2024.
One of the most common fault codes for the E-Class is certainly not one of the most common in general. Code P0715 indicates a problem with the transmission speed sensor.
This can be a serious issue as it can prevent the gearbox from shifting properly, and sometimes even put the car in limp mode. Owners have reported that this is typically caused by a faulty speed sensor, which can be replaced.
Another fairly common code is P0172, which can affect most Mercedes-Benz models. This code represents too much fuel in the air-fuel mixture. The code itself does not help pinpoint the cause though, making it difficult to address.
This code is reportedly caused most often by poor maintenance of components like the MAF sensor and air filter. If these parts get fouled up, they can provide incorrect information to the onboard computers, causing a fuel issue like this to be logged.
Another code the E-Class reportedly suffers from is P0400, which is the least serious one. This code represents an exhaust gas recirculation (EGR) flow malfunction.
This can have little to no effect on the engine, except during starting in cold environments. This can typically be resolved by replacing any faulty components in the EGR system.
