Mazda dpf queries

swanie29

New here wondering if you guys could perhaps help me. I bough a mazda 3 2.2 disesl 2014 saloon with 128000 on the clock with full service history from mazda only six months ago. Now just before Christmas I got four errors appearing on my screen in the car from engine management to tcps malfunction, scsb malfunction and another error so four in total. So I took it to my guy and hooked up to OB2 reader and it came up with a pressure sensor fault. Now was told the pressure sensor was a modified sensor and could only be got from Mazda themselves and paid over two hundre for the part and what ever else to in labour. Now before that all came about they changed the oil first saying that there was a slight raise in the oil and that the car had been trying to regen but had fail and had lead diseal into the sump just was the cheaper option but it didn't work. So moving on the lads replaced the parts but the pipe leading to the dpf is completey blocked now I only done 8000 miles since getting the car but was told the dpf should not have any issues when buying it as was told it was fine.


Wondering would 8000 miles enough to clogged pipes. I drive on average 50 miles a day average 70-80 mph. Any one offer any help.

I thought the best option would be to delete dpf as there a very common problem with dpf when it regenerating dumpling diesel into the oil and if you don't catch it in time destroying the engine.

I say it probably would most car burn soot every 300 to 500 miles . 6 months ago you bought it was it for a dealer ? Is there any warranty on it . Previous owner could have got rid of it because he know the dpf was on way out
I know what I be doing if dpf on Mazda was giving problems

Someone more knowledgeable about Mazda will probably reply soon

If i can find a way to prove the carbon was bulit up before I bought the car might be help

If it was me I would just get it deleted .I don't think it be worth the hassle trying to get dealer to fix it and even if he do if it goes wrong again and dump diesel into oil could destroyed engine...take it the dealer you bought it from have no interest in fixing it under warranty? Plus how much are they saying it will cost to fix

Waste of time going to Mazda either get the DPF deleted and mapped out or get rid of it. Plenty of similar threads if you search.

Ya see my mechanic could tell me that oil level had risen due to disel mixing with oil but as I said I said I only done 8000. Miles and there is a lot of carbon here

I even spoken to a few guys and dpf cleaner guys and said no way that much carbon would build up with my 8000

Yeah did he fix it or did you get your own mechanic to fix it

I had to get it done myself cause my mechanic advised me not drive it but the garage is not in Dublin but the garage wanted to charge me regardless and it was before Christmas

Talk to a solicitor maybe. That error code is something to do with turbo hopefully when dpf got blocked the back pressure didn't damaged turbo.

I would of thought the garage is liable for telling me the dpf was sorted and not to worry but 6 months on it silly carry on . I think I start a Facebook post and get it shared about these crooks

Dpf in Mazda are notorious, also not usually covered under second hand warranty.
I don’t think you’ll get far tbh.
Getting it removed/remapped would be my choice.
