Hi,
I have a problem with one of my cars at the workshop. The car constantly throws out three code errors: 
1. P0100-4
2. P0110-4
3. P1901-4

VIN: W0L0XCF0694310492
Engine: Z13DTJ

DPF Flow resistence: 54.96
DPF: 34.51%
Differential Pressure DPF: 0.68V
Differential Pressure DPF: 7kPa
Intake Air Temp: 40 C°
Mass Air Flow Sensor: 97.26 kg/h

I put new MAF sensor and differental pressure sensor. And still same fault, car enter safe mode. What I can do to fix this? Should I try with second ECU?
