If you go back and watch the first set think it was day 6 or 7 the wynns was used in two doses, overnight and the following day

Days 7&8 just checked

This is the second time round, theres a whole set of vids taken over a week where I cleaned the dpf before and thought I had done it.

08 PLATE MAZDA 5. You need to watch the previous vids especialy the first one and maybe the third

@@bosseyedbeardedbloke Ok - well seing as its a Mazda - the problem will be carbon build up in the DPF pressure tube You really need to have the live data read - once the DPF is back on the car The DPF is NOT THE PROBLEM it is a SYMPTON of something else The Mazdas are TERRIBLE for carbon build up especially if just used around the doors Hope this info helps

cant really answer any of that all i can say is that the dpf was so blocked the car would barely run and if you watch the first video you will see how hard it was to get anything to go through it. 7 and 8 is edited and ready but just didnt get time to upload it this evening but i am going try try and remove that sensor tommorow.

great job, dont know half of what your talking about but it sounds like you know your stuff, just hope mine turns out as good, I am worried about that 02 sensor though

@bosseyedbeardedbloke I would assume you have possibly two sensors which if removed would look like long needles these would more than likely be the temperature sensors. One is normally located up stream of the dpf and the other sensor would normally measure the dpf temperature itself. And not on my car but other cars like yours, you have another sensor which would be the oxygen sensor. The oxygen sensor itself can be cleaned using things such as brake cleaner or contact spray / electrical spray. I'am sure someone will correct me but you may possibly if you can remove it easily enough leave it in some electric contact cleaner over night then allow a few hours to dry. It hard to say if it's completely ruined by the cleaning you have done as some garages near me have done some very weird things to clean dpf's out and have left sensors installed while doing so. It maybe a good idea to try and remove them all and make sure you photograph or mark which sensor comes from which location.

@@Ivan-gm7zb just ordered some contact cleaner so will give it a go. Thankyou so much for advice but if it doesnt work dont worry as I will have removed and put back on which would mean removing on car should be easy

was targeting the ash, but your probably right

Thanks for the comment but whats the 02 sensor?

@bosseyedbeardedbloke the O2 sensor is the part that's screwed into the neck of the dpf, inside the tube it's the bit with all the little holes in. Getting them wet with anything apart from carb cleaner usually knackers them. Should really remove it before cleaning (22mm spanner), but they are a bugger to get out, usually need heat and a big pipe on the end of your spanner
