故障现象一辆行驶里程约为4.2万km的2013款大众途锐SUV车(搭载3.0 TSI发动机),据驾驶人反映,该车在高速行驶过程中突然抖动严重,熄火后无法起动。故障诊断接车后,首先验证故障现象,故障确实存在。连接故障检测仪,读取各系统的故障存储器,01-发动机控制单元中存储的故障代码如图1所示,故障状态为主动/静态,根据故障代码初步判断3缸火花塞有故障或者3缸的气缸压缩压力过低。拆下火花塞检查,发现3缸的火花塞被
Symptoms A 2013 Volkswagen Touareg SUV (carrying a 3.0 TSI engine) traveling at a speed of about 42,000 km reported a sudden jitter during high-speed driving that could not be started after a flameout, according to the driver. Troubleshooting After the car is taken over, the first to verify the fault phenomenon, the fault does exist. Connect the fault detector, read the fault memory of each system, 01-engine control unit stored fault code shown in Figure 1, the fault status is active / static, according to the fault code to determine the initial 3-cylinder spark plug is faulty or 3-cylinder Cylinder compression pressure is too low. Remove the spark plug inspection and found that 3-cylinder spark plug was
