ciao ragazzi, é da qualche giorno che avevo la spia avaria motore accesa, oggi sono andato in BMW e mi hanno detto che é la valvola EGR da sostituire, ho anche fatto una diagnosi con l'adattatore Carly per BMW, questo é il risultato: Found Faults: --Engine / Motor-- *** 4CAE:Abgasrueckfuehrsteller position sensor signal *** Fault-Set 1 - ( 99720 km) Activation period for the main injection 1: 590.84 us Current Motorabstellzeit (2 bytes): 157110.00 s Current value of accelerator pedal signal 1: 0.00 mV Exhaust backpressure before particulate filter - corrected: 0.00 hPa Exhaust gas temperature before catalytic converter - corrected value (1 byte): -50.00 degC Filtered flow resistance of the particulate filter: 0.01 hPa/(m^3/h) HFM-shutdown: 0.00 - Injection amount PoI2 before correcting the fault monitoring: -100.00 mg Injection type injection place specifications: 0.00 - Kraftstoffvorförderdruck - Spannungsrohwert from the sensor (1 byte): 96.08 mV Linearized error untreated ATL actuator position (1 byte): 0.39 % linearized value of the fuel pressure sensor: 640.00 bar MoCSOP_ctErrMM_mp 1: 0.00 - MoCSOP_ctErrMM_mp 1: 0.00 - MoCSOP_ctErrMM_mp 1: 0.00 - MoCSOP_ctErrMM_mp 2: 16.00 - MoCSOP_ctErrMM_mp 3: 136.00 - MoCSOP_stMm_mp 0: 0.00 - MoCSOP_stMm_mp 1: 0.00 - Offset of particle filter differential pressure (1 byte): -49.80 hPa regeneration status: 2024604672.00 hex Ring memory with the last 8 Reset IDs 1: 0.00 - Ring memory with the last 8 Reset IDs 2: 0.00 - Ring memory with the last 8 Reset IDs 4: 0.00 - secondo voi c'é la possibilità di risolvere smontando la valvola e pulendola o é proprio da sostituire? grazie, Alessandro
