Today I flashed the tuned file into the car then the engine MIL and "EPC" illuminated in the dash. I found three DTCs in the engine: P0104 (MAF sensor) + P2237 and P2251 (lambda sensor 1). Before applying the tuned file there was no DTC in the engine and everything was working fine. I mean the EGR and the DPF and the Adblue were all working fine. Now the max speed is arround 60 Km/h and sometimes 30 Km/h.
