If you have owned or currently own a Land Rover Discovery 2, I bet you have seen this warningView post light or paid your local Land Rover Shop to fix this problem. This is the amber colored “Service Engine Soon” light. This light is commonly referred to as the “Check Engine” light. Basically, this light comes on because your Land Rover Engine Computer stored a fault code related to the emissions of your Land Rover. Within your emissions control systems, the Evaporative Emission Control System (EVAP) controls the vapors given off by the liquid gas in your fuel tank. The main automotive part in this system is the “Fuel Cap” or “Gas Cap”. This is that part we forget to tighten when we leave the gas station in a hurry.

A loose or not fully seated gas cap will turn on your service engine soon light
Since this is so common, do this simple and easy check when your “Service Engine Soon” Light comes on. Open your fuel door and double check to see if your cap is fully seated. Please refer to the photo on the top of this page. You will see an arrow pointing at the white plastic threads of your gas cap. Bend down and look at your gas cap from a lower point of view similar to this photo. Do you see any white plastic threads? If so, tighten your gas cap until these threads disappear from view. If your gas cap is tight and no threads are showing, then most likely your check engine light is on for another reason then the gas cap. You could still have an Evaportive Emission related concern.
