The DPF light is on and I have been told that the filter itself is clogged and need some advice on where to take it in the Midlands area. Hello. I bought a Mazda 6 recently and the DPF light flashes intermittently, sometimes for the best part of the day which sends the car into limp mode but every time I visit a mechanic, they say there are no codes stored on the ecu. can anyone recommend a specialist that knows what they are The good news is that forced regens don’t have to be a recurring nuisance if drivers reduce impurities entering into the DPF at the start. A premium diesel fuel like Cenex Roadmaster XL can Icant force a natural regen with the wire trick as when the eml light comes on it kicks it out of forced regen! I did however force a regen with the fault code reader connected and constantly clicked the clear faults which seemed to perform the whole regen in just under 1 hr, however the dpf light didnt go out and the eml light came straight Mazda 6 2.0 143 Diesel P242f code P242f code won't stay cleared.? and activates limp home mode and engine management light comes on. Earlier in the year the DPF light started flashing. I did a forced Regen and it cleared. Around September the DPF came on flashing on a long run then stayed lit up solid plus activated the engine The car is not roadworthy with a nonfunctioning DPF, so for using let alone selling it (depending on state) it needs fixing. Cleaning is probably cheaper, so that would be better for selling it as long as it works. I would want some assurance about the latter. User #308881 1079 posts.
If it does not, the regen has not started and you need to start back at point (2) 5. The DPF forced regen process will take between 40 and 80 mins depending on how badly blocked the DPF is. NB. Do not touch the accelerator or clutch as this will cancel the regen cycle. To purposefully cancel the forced regen, place the vehicle into 1st gear. 6.
Eventually the DPF light started flashing and in turn the engine light came on and I believe the car has gone into “limp” mode. I have tried putting the car into forced regeneration mode using the wire from sensor to earth point trick. It enters forced regeneration mode and then immediately returns to normal. a oil change must be entered into the ecu diagnosticly, if the ecu thinks the oil is past its saturation level it will not regen, i got a mazda 6 recently with knackered dpf, added treatment sat on motorway 2500 rmp for 25 miles, came home told ecu oil changed done cleared codes good as new, but dealerships wrote the car off with a £1000
The super fine dust of the exhaust combines with oil and creates a thick sludge in the intake manifold. This then can flow down into the DPF and cause further clogging when really it's not the DPF. I've looked at 4 different diesel Subies, 3 of which have history of recurrent DPF issues and have undergone forced regen / DPF replacement.
6) In order to carry out a forced/emergency static DPF regeneration, use the correct diagnostic machine. 7) If the engine management light comes on first, followed by the DPF light, it indicates an issue within the DPF system, for example temperature, pressure, sensors etc. 8) Ensure the vehicle is parked outside, in park/neutral, the hand Never let it get above full. Change oil as often as possible and after any garage forced regeneration. Removing/gutting dpf, fixing whatever other issues are present may be only fix short of scrapping car. The dpf will continue to get blocked if something is causing engine to be "smoky" . Replacing dpf for say 1000 euro is no good if it blocks USAF. Current Ride. 2021 F350 6.7 Tremor Lithium Gray. First Responder. Retired LEO. New to the 6.7L and I did not know much about regen and found this video on DPF regen and thought I would post up. I am thinking this info is still fairly accurate for the 2020’s. So much for swapping out exhaust tips. zThff.
