Common Contexts
There are several common contexts in which the “Service DEF System See Dealer” message may appear on your dashboard. These include:
-
Overfilled DEF tank: This is the most common cause of the message. Overfilling the DEF tank can cause the fluid to expand and overflow, leading to issues with the system.
-
Faulty sensor: The DEF system relies on several sensors to function properly. If one of these sensors is faulty, it can trigger the “Service DEF System See Dealer” message.
-
DEF contamination: If the DEF fluid becomes contaminated, it can cause issues with the system. Contamination can occur if the fluid is stored improperly or if the wrong type of fluid is used.
-
Cold weather: In cold weather, the DEF fluid can freeze and cause issues with the system. It is important to use the proper type of DEF fluid for the climate in which you are operating your vehicle.
In summary, the “Service DEF System See Dealer” message indicates an issue with the DEF system in your diesel vehicle. There are several common contexts in which this message may appear, including an overfilled DEF tank, a faulty sensor, DEF contamination, and cold weather.
