Hi guys. Just to make this clear from the off, i am in no way mechanically minded & have of course looked online for the answers to my questions but have been blinded with jargon so if anyone can give me an idiots guide then this idiot would be very grateful!
I've owned a 56 plate for just under 2 years now. The car has just done over 150k miles. Recently the DPF has started flashing. Took it for a much needed motorway run at 3000 revs for a good 30 mins with no luck. Did a little investigating online which led me to check the oil. It was past the F mark and up around the dreaded X. So today i took it for a full service & oil change. Then on the way home took it for another 10/15 min motorway run in 4th gear at 70mph with about 3500rpm. The light continues to flash.
From reading online i'm guessing the light doesn't just turn it's self off and requires it being plugged into a machine to do this. I have seen on youtube the trick for turning the light off without going to a garage but obviously don't want to do so if it is a genuine warning. So how do i know that the oil change and/or the motorway run has worked or not?
Thanks in advance for any help...
I'm guessing that your oil/filter change was done by a garage which doesn't have the facility for resetting the DPF light. A main dealer would have done this as part of the service.
The flashing DPF light is acting as a service warning light. If the light is on permanently, then, usualy, this means the DPF is very badly clogged which is a far worse situation.
My car is similar to yours and I have used the tips found here
http://www.cdn.dk/mazda6/tips.htm to good effect I have done them all except for the automatic wipers as my car doesn't have them.
Only the other day, I used the procedure for recalibrating the injectors and this made a very noticeable difference to the car's performance.
The DPF cleaning process is quite brutal and somewhat alarming as the engine revs up and slows down of its own accord and, at times, runs roughly. But it works and everything settles down, in the end.
I was quite apprehensive when I first used the procedures. I thinks many others have done the same with success.
