Might be an idea to daily check the soot loading with forscan if you are going to keep driving it, just in case.
If it gets too high (don't know exactly what's too high) the DPF may not regenerate.
The max is usually around 80% on mine.
The differential pressure sensor and hoses are another possibility, and the vapouriser cokes up:

Hopefully a glitch.
