About the GLB-Class

The first and only generation of the GLB-Class made its debut in 2019. As its name suggests, the SUV is positioned between the GLA and GLC in terms of sizing.

Like the other SUV models in the Mercedes lineup, its name follows the standard naming convention of ‘G’ to represent the SUV models as an homage to the iconic G-Class. The ‘L’ is used for the series of SUVs and the ‘B’ indicates the model’s size.

Competition from outside the company comes from the Land Rover Discovery Sport, BMW X3, and Volkswagen Tiguan AllSpace.

The most common fault code for the GLB is one that is known to affect a number of Mercedes models. Fault code P2006 represents a malfunction with the intake manifold runner.

This issue can be fairly difficult to fix, but thankfully, there is a lot of information available on fixing the problem because so many models have suffered from it. Owners have typically found replacing the faulty actuator as the best course of action.

Fault code P0455 is another fairly common problem for these models. This code represents a leak in the EVAP system. One of the most common causes is a loose gas cap, but there can also be actual leaks in the EVAP hoses or components.

Another relatively common problem is P0128, which indicates that the engine coolant is not reaching the desired temperature. This is another issue that affects a number of Mercedes engines.

This can be caused by a faulty thermostat, as well as incorrect coolant fluid levels. Thankfully, both of these can be relatively easy to fix by yourself.
