I have a UK spec mazda5 2.0 Diesel sport. It started running rough, slow like in limp mode and smoking a lot.


A Diagnostic was doing and it stated injectors faulty, injectors replaced, then it stated mas air flow fault. Mas changed, then I got traction control warning light with DPF and engine light. Diagnostic still states mas faulty and injectors. Car required oil change to perform regen but won't do the regen. I am at a loss on what to do...
Can anyone help?????

 

Who's been working on it?

As far as I know, only Mazda dealers can do a forced DPF regen.

 

OK, full update on this problem. The bottom end was on it's way out. Oil got into the DPF and caused the warning lights. I've had another engine installed and a new DPF. I will be collecting her tomorrow about 12 noon.

 

Wow, congratulations, glad that you fixed the problem
