Early this year I removed a dpf and used Wynn's dpf cleaner. Blanked off any pipe fittings and the turbo side of the dpf. (Back flush) Filled the dpf with the cleaner and left it overnight. Removed the bung and washed with cold water left it to drain for a few hours, refitted and job done. I just recently replaced the egr cooler and egr and the plastic intake pipes as ford doesn't sell the gaskets separately. With over 90,000 miles the car now has a very hard boost pull and black smoke is reduced by over 78%. Even if you do loads of motorway mileage which i don't the direct injection manifold will still get clogged which is now a job for another day 😳 Hats off too you with your different efforts in dpf cleaning 👍👍
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
The O2 sensor - is a Nox (Nitrogen Oxide ) sensor they are fairly resiliant - BUT if I was you I would loosen it off and get it free while the DPF is off the car Heat the boss that it screws into and then keep heating & cooling it with WD40 - or similar - it tends to do the job What exactly was the origional fault with the car ?? Remenber - the DPF is the last in the line and do not just block up - ANOTHER fault will be causing it to block Unless you address the fault it will just keep blocking Do you have any fault codes - or can you get the ecu read for faults ?? There can be a fault but NO LIGHT on !! These Mazdas are terrible TOO much emissions stuff on them
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.

vinegar does not work on dpf and soot..
was targeting the ash, but your probably right
