DPF warning light but not a DPF fault (according to the garage) any thoughts!?

[Don]

Hi, hoping for a light bulb moment from avid CR-V fans. 

My DPF alarm illuminated on the dash about 3 months ago and went into limp mode. The garage conducted a force regen and sent me on my way. All was good for about 2 months until it happened again. 

This time my local garage couldn't clear the fault so I took it to a terra clean "specialist" who charged me a small fortune, cleared the fault, force regen again and said that all my stats were good and maybe my previous garage didn't regen it correctly. 

Fast forward 25 miles and it's back on. 

Any thoughts please? Because I can't keep taking it in for them to charge me the world and it go wrong in less than 24 hours

It sounds like it could be a sensor at fault if the DPF and regens are okay then it is the only thing that I would be leaning towards.

Maybe that or a software update, worth contacting your Honda dealership to enquire if this is the case
