If you still have a DPF and want to keep I would not clear it and show it to the dealer ASAP.

If you do not have a DPF check all your exhaust sensor connections.

Another thought- If you have an edge AND a DPF it is likely the Edge that is causing the DPF to fill. Might want to take a long drive on the freeway or somehow get that regen thing going on.
