Hi all, looking for some guidance on clearing a persistent DPF warning light on the dash.
It's a 2015 Mazda2 1.5 Skyactiv‑D (diesel), that I've just had the DPF taken out and professionally cleaned a few weeks back (the ECU was reset too). Its on 85k miles.

Strangely I now have a DPF light showing which can't be due to the actual DPF as there hasn't been sufficient time for soot build up... It hasn't gone away with motorway regen either and the garage that did the overhaul have since plugged it in and are seeing no codes they can clear on the computer either.

Apparently the DPF differential pressure sensor hoses being partially blocked could be the issue, giving false readings and keeping the lamp on? I haven't managed to locate them in the engine bay however.

Keen to get this light to stay off. Thanks!

 

Welcome to the forum

 

The rubber hoses going to the sensor dry and crack with time. I suggest you get a scantool and read it for codes and also check live data which will tell you what you need to know to proceed. A scantool and a vacuum pump should tell all.
