Nice to meet you guys, I'm the owner of the 5th generation R32. Currently, I have the fault code P1545. I replaced all throttle body, MAF sensor, fuel pump, ignition coil, ignition plug, throttle body connector, but I still have P1545. When started, the idling condition is unstable and maintains 1000 rpm. The EPC and ABS warning lamps will then appear in the instrument cluster. However, it sometimes changes to P0122, P0222 code, not P1545. Is this an ECM issue?
