DPF Reset? Help
 

Hi folks, I'm sure there's a thread somewhere on this already but I cannot find anything. I have a 2008 Mazda 3 Sport 2.0L diesel and I need to reset my service indicator which is also the DPF light. Can anyone tell me if this is possible to reset without visiting my Mazda dealer which is over 200 miles away from me (live in the North of Scotland).
I've seen lots on the newer 2.2 diesel & how to reset this but nothing on my engine.
Any help would be really appreciated
