The only other thing I can think of would be oil (usually from a leaky seal in the 'cold' side of the turbo) or coolant (head gasket) making its way to the DPF.Funny you mention above items. They replaced dpf and pressure differential switch, I have replaced the silicon boot just after the turbo. Injectors we’re fine at 235k miles.
Those are rare as you'd notice the levels dropping before having issues with the DPF, unless it just failed miserably.
