The most common issue for the V-Class is one that affects a large number of Mercedes-Benz models. This is fault code P2006, which indicates that the intake manifold runner is stuck closed. This is a serious issue as it can cause performance problems and damage to the engine.

Another fairly common issue for the model is P0455, which represents a leak in the EVAP system.

This is typically caused by faulty components in the system. Owners have reported the hoses in the system tend to come loose in some instances. Another fairly common cause is a loose gas cap.

P0128 is another problem that commonly affects Mercedes-Benz engines. This code indicates that the engine coolant is not reaching the ideal regulating temperature.

One of the most likely causes for this issue is a failed thermostat, which should be replaced. It is also a good idea to have the coolant replaced to the correct level as having both too high or too low levels can cause this issue.

Owners have also reported that leaks in the cooling system can also cause this problem.
