Mazda 5 2.0 diesel DPF flasking and engine management light issues

[Falcomille]

I am now into the 6th month of ownership of this otherwise excellent car. However, the car does spend an inordinate amount of time at the local Mazda dealer being fixed. New DPF filter, Sensor, numerous wiring checks, regens later.. all failing to rectify the problem, Mazda France have now removed the injectors and sent them off for testing. I have also suggested to them checking the engine oil is up to spec, checking the ECU firmware revision, checking/cleaning the EGR valve and MAF sensors while they are at it. Can anyone recommend anything else before the warranty expires?

And we now see why Mazda was so reluctant to begin selling the new 6 diesel here in America, the land of the drive-through lawsuit LOL. To the OP, sorry I can't be more help, but I wouldn't want
to keep a car with known issues that aren't getting fixed.
