My friend deleted the DPF right after buying the car as he was driving short trips he knew filter would clog up and there wouldn't be enough time to regenerate. DPF clog up can be increased by worn camshaft. As it wears out engine efficiency drops and soot increases. That happened. Could pass emissions tests before without DPF but with bad camshaft couldn't. Disabling EGR prevents the carbon build up in the intake. Carbon build up is because PCV + EGR. Either one of them won't cause the issue but together they do. PCV oils the surfaces and then soot sticks to it forming a deposit. Or you can keep the EGR but do the vent to air crankcase ventilation. OR keep both and just clean the intake from time to time :D
I had a DPF delete only on my Toyota Avensis 2.0 D4d, and it totally transformed how it drove. Excellent fuel economy and power. My vehicle just seems to be free flowing. Work carried out in 2017, not had a problem till this day, best £350 I’ve spent. Thanks 👍
Seems I might have just been stung with a DPF delete on a Mazda 6 2.2 diesel that I bought back in May. DPF according to FORSCAN hasn't regen'd in 23,700km, which adds up to the date it was supposedly 'cleaned' by the previous owner. Very sooty exhaust pipe and reads near 0.2kpa on Exhaust gas differential pressure (DP_DPF).
This was the issue I had,dpf delete advised by cowboy mechanic, but didn't improve anything,unable to trace faults due to no readings on scanner,so paid again to remove the dpf software and bought another dpf,then found it exhaust pressure sensor was blocked,😢
@hash-CCFF00 none,but when I started getting issues my mechanic couldn't diagnose due to the map,so no live data readings on some of the sensors,so bought another dpf and had the map removed
I can't figure out why the dpf regen didn't start. Travelled about 1000 km, 8 successful regenerations, once I had to interrupt it, there was a stop in the mountains, but then after starting the engine and starting to move it started again and did its job. But after the mountains, went to the motorway and found (forscan pid pm_acc ) that it would be time to start regeneration, but it did not start. The error p2458 appeared first and then the cherished p2463. What assumptions can be made? Can it be in the exhaust gas pressure sensor ? My car takes a long time to warm up in winter, maybe the thermostat is glitchy and cools the engine down a lot as I noticed the fans coming on frequently. This has not happened before. I will be glad of any help. 😉
Mazda 2 1.5D 2016, serviced every 10000km (6200 miles), after two years of problems (regenerations every 50-100km (30-60 miles)), after having the DPF warning light twice, at only 80000km (50000 miles) I was advised to remove the DPF/EGR and so I did. The car only makes smoke if you do big accelerations. Since most people has the problem, I gave up spending money to solve a problem that would recur in months or years. 80 per cent of the time I do road trips that are at least 300km (185 miles) long. The injectors I think are OK as I can do 4.0L/100km (59mpg) without too much effort. The mechanics also told me that it is difficult to find the problems while the DPF/EGR is in place.
Do you recommend doing a dpf delete? I was considering doing it because the whole egr and dpf system kills these engines quicker by circulating the exhaust gases. What do you think?
do it if you are kinda poor, take short trips daily and stay in a large field. the only cons are rare computer codes if not done by experts and ofc cancer causing causes.. so dont keep it in a garage, make sure its an open field and the gases dont enter your home or else your asking for cancer in a few years..
Personally, I am not a fan of diesel engines to begin with but beyond that I care about the air quality we breathe everyday and the environment/ climate. Too many people don’t care but expect the car to take care of itself. The same people who delete their DPF and or EGR valve are always the same people you see each time at the pub drinking and smoking like they are rich . Actually I have seen people with lots of money never get oil changes and get angry when the car breaks down
Good point. Also disappointing to see that this is common in the UK as well. DPF off means cancer on. The sooth particulate become permanently trapped in the lungs. It is not whether someone cares about the environment, but for people's health in general.
No, I would definitely not delete the dpf or egr system. As you say, it is masking the problem, not to mention being illegal, polluting the environment more, and you run the risk of mot failure/refusal for you or future owners. I understand why some people do it, I'm going through the whole expensive nightmare myself, but I'm attempting to fix it the correct way, and when I sell on, I'll be offering advice on how to minimise carbon build up with these engines. Personally, I wouldn't want to spend 4 or 5k on a car that had this done just to mask other issues, and I wouldn't do that to anyone else.
After repairing turbo and removing DPF , change filter in carter ,remaping comp,all problems disappeared but I stil think this Mazda CX 52.2d is for me worst mistake that I did in last 25 y buying owning cars...I hope this car last few more years and never again MAZDA or any diesel car unless is a van...👎👎👎👎👎👎👎👎👎👎👎👎👎👎👎👎👎👎👎👎👎👎👎👎

Really clever. Enjoy your cancer.

what performance differences were you noticing during the blockage?

mine mazda 6 regens every ~100-110 km.... pain in the a** indeed!!
did the removing solve your problems
Butterfly guys and professional mechanics
Do all the required repairs + delete DPF and EGR and remap.

Great video but surely its illegal to remove or disconect the dpf
No, I would definitely not delete the dpf or egr system. As you say, it is masking the problem, not to mention being illegal, polluting the environment more, and you run the risk of mot failure/refusal for you or future owners.
