its the sensors on the exhaust that tell the computer that its full. It reads how much soot is going by the first sensor and how much is going by the second sensor if its the same then it says its full because its not filtering. so by removing the filter it thinks its full. you need to put a new filter on or just live with the light

This can be very agrivating problem.I have been chaseing a problem like this for a year now.The first place to start is battery and all other ground and electrical connections you can get to.go to parts store and get a can of electrical cleaner and go to town.Hope you have better luck than i had.It could also be a wire touching exhaust or rubed thrue somewhere.

Not 100% sure at the moment, but will get back to you. Check behind kick panel by passenger right foot position in meantime.

cant see all of your problem..did you replace filtre?is your vent hose pinched off?
