Hello,I will be glad to try and assist you with this,Welcome to Just Answer.I may need more info in some cases to help with answering your question.

Is this the amber light that is on and is any other lights on on the dash on the vehicle?

Was anything done that may have caused this light or anything else done to try and correct it?

Let me know,thanks Pete.

I don't understand your last reply here,does the light that comes on on the dash look green in color,yellow in color or red in color?
Customer: replied 4 years ago.

the display says the tank is full, and is green.

O.k.,if it is green then this indicates the engine is in regeneration mode here.Allow this to run and complete by either parking the vehicle in a safe dry area with no leaves or debris under the exhaust and press the regen button on the dash and allow the cycle to complete.In some cases you may have to use a scan tool plugged into the vehicle to run the regen mode but being green in color it should run and complete on its own.You can either drive the vehicle until the light goes off or park and idle it and press the regen button to allow it to run its cycle then the light will go off.

Here is a video of your vehicle and how this is done:

About 2 minutes and 50 seconds into the video it starts to show how this works.

Let me know if you need anything else,thanks Pete.
