1, models: Bora 1.8TAT failure: self-extinguishing phenomenon in the driving, the engine immediately after the start flame, after which can not start. Check: Check with the VAG1552 engine has a fault code: "16706-engine speed sensor G28 no signal." Replace speed sensor still can not start, but did not remember the fault code. Remove the 1 cylinder ignition coil and spark plug, start the engine found to have high-pressure fire, unplug the fuel rail inlet pipe found no gasoline outflow, the wire directly to the fuel pump power does not rotate. Analysis: The fuel pump motor is still not directly energized, indicating damage to the fuel pump. Exclude: replace the electric fuel pump, troubleshooting. 2, throttle body too dirty led to ASR lights Model: Bora 1.8TMT Mileage: 35000 km phenomenon: driving sometimes slip ASR warning lights lit, but no impact on the road, the maximum speed, acceleration performance are normal. Check: Use VAG1552 read 3 fault codes: â‘ engine air flow meter signal is too low; â‘¡ G188 signal is not correct; â‘¢ throttle idle speed overrun. Analysis: Throttle throttle body too much opening, reaching ASR lamp alarm conditions. Exclude: cleaning the throttle body, ASR warning light goes out, the car tracked mileage 45000km, the fault did not reappear. 3, G212 fault code, to be used for exhaust gas recirculation valve settings Model: Bora 1.8 fault: engine idling jitter check: Use VAG1552 query to two fault codes: â‘ G212 fault; â‘¡ 1 cylinder, 2 cylinder injector short to ground malfunction. Read data flow idle throttle opening 1.9%. Exclusion: Use VAG1552 to enter 01-04-074, set the exhaust gas recirculation valve, display OK, no fault after inquiring, the engine vibration disappears.
