People Hi, I'm Marko from Croatia. Three months ago I became owner of Mazda cx-3 1.5 cd 77 kw 09/2016 year. Car have 120 000 km . Two weeks ago, problems with dpf regeneration begin . Oil was on X flow so they changed it to the mazda service and said I needed buy all new injectors . I'm out of factory warranty for replacements, and I have to buy them self . They are very expensive, all cx-3 diesel engines have had problems with the injectors ? I'm wondering if I'm looking for an injector from a damaged car? Please help because in Croatia, Mazda's services do not have much experience .I apologize for my English if I wrote something wrong .I mostly have a problem like a guy in this post . Bay.

Mine were replaced under warranty with the car in its 3rd year and approximately 10,000 miles. I don't have a record as Mazda don't provide written records of warranty work.

Hi Marko, obviously I don't know if your CX-3 needs new injectors, but it's not all engines. I have done nearly 44,000 miles, and it gets an oil change when it says it needs one (in the UK that's at least every 12 months or 12,500 miles whichever comes first) with Mazda oil at a main dealer.

The oil and the filter were changed in the Mazda's service. They have regenerated through diagnostics.After the city drive maybe 300 km again turned on the regeneration light and continue to drive and the light starts flashing and writes to the display dpf problem .

According to Mazda Repair Guidance R032/17, issued to authorised repairers May 22 2017 --

Some CX-3's may experience the “Wrench Indicator Light” illumination with the “Oil Change Due ” message on LCD and DTC P252F:00 stored in PCM memory (Engine oil level high, above or near “X” mark)

That's how they told me in mazda service, often and constantly launching DPF regeneration .That means they can look for other replacement injectors, it's Denso's manufacturer .There are already repaired injectors on ebay, I have to send my old ones and pay .If I solve the problem I will write to you and thank everyone.

Good morning, Denso replacement injectors no. 295700-04 cost a new set of four pieces whit replacing in mazda servis 2000 gbp .I do not even know what to do, my injectors are just bad . I found injectors S56013H50A from a damaged car with 6000 miles made . Injectors look are new .I'll buy them and sell the car right away .It is not clear to me, and in Croatia in mazda servis will not tell my if all cx-3 diesel had this problem in warranty or just some cars .They say these Denso injectors are gray color and the original black and brown color .

jtucker. I’m not prepared to put the process on the forum because it is a special procedure. If you send me a private message, I’ll give you some contact details and we can discuss exactly what is going on with your car and then I’ll tell you about the forced regen process.
