VIN:LFV3A24FXB×××××××。行驶里程:120000km。车型:配置BPJ 2.0L R4/4V TFSI发动机,01J变速器。故障现象:车辆行驶至中高速以后动力不足,急加速时没有推背感。利用诊断仪检查,除发动机控制单元外,其他各电控系统均正常。发动机控制单元内有自诊断故障信息,如图1所示。发动机控制系统中的自诊断故障码,可以清除,但车辆中高速行驶后还会重复出现。根据故障现象,结合自诊断故障码,初步判断为涡轮增压系统故障。发动机控制系统有两个OBD故
VIN: LFV3A24FXB ×××××××. Mileage: 120000km. Model: BPJ 2.0L R4 / 4V TFSI engine configuration, 01J transmission. Symptom: vehicle driving to medium and high speed after lack of power, did not rush to promote the sense of acceleration. The use of diagnostic tests, in addition to the engine control unit, the other electronic control system are normal. There are self-diagnostic fault information in the engine control unit, as shown in Figure 1. Self-diagnostic engine control system fault code, you can clear, but the vehicle will be repeated after high-speed drive. According to the fault phenomenon, combined with self-diagnosis fault code, initially determine the turbo system failure. The engine control system has two OBDs
