Dear all, i have a mazda 6 2008 2.0 dizel, 103kw with DPF.
My mazda is showing this code all the time, i cleanded maf sensor, egr, dpf, and the code is still there. My car has problems like , hesatation in acceleration, rough motor and knocking noices. Some days the car is working great but the other days i have problems. But, no light on my board.
can those problems make the BARO sensor inside the ECU?
And I went in 4 mazda dealers and they didnt know to solve the problem. Sorry for my English :)
