Mercedes Benz G-Class Fault Codes

About the G-Class

The G-Class, also called the G-Wagen, is one of the oldest and most iconic models in the Mercedes-Benz lineup. It was first released all the way back in 1979 as the W460.

Since then, there have only been four generations, with the name G-Class first debuting in 1990.

The release of the Mercedes-Benz GL-Class was supposed to replace the model, but sales have continued to remain strong even today. In fact, there has been somewhat of a resurgence for the model in recent years due to its popularity amongst celebrities.

The model has faced competition from other high-performance luxury SUVs during its 40+ years on the market. These have included the Land Rover Defender, Lamborghini Urus, and BMW X7.

Being fitted with such powerful engines, particularly in AMG models, means there is always room for problems. One of the most common of these is fairly broad in scope. Fault code P0171 indicates that the engine is running too lean.

This can cause a huge host of issues when it comes to the G-Wagen’s performance. Unfortunately, it can be a massive undertaking just finding the cause of the issues, let alone repairing it. This is even more true with today’s offerings featuring highly complex engines.

Another fairly serious code is P2006, which is specific to Mercedes-Benz models. This code means that the intake manifold runner is stuck closed. Just like the previous code, this is a serious issue as it can cause performance problems and damage to the engine.

One of the most common causes for this is a faulty intake manifold runner. Other issues can include faults in the runner’s control circuit like damaged wiring.

To make things worse, both of these codes can be very serious. Owners should have them addressed as soon as the code appears to protect their costly SUV, as well as avoid even more expensive repair bills.
