How is the quality of the JLE-4G18TDC engine?
1 Answers
The 1.8T engine model JLE-4G18TDC delivers relatively strong power, with a maximum output of 135kW (184Ps) and a peak torque of 300Nm. This engine complies with the National VI emission standards. The reasons for engine jerking are as follows: 1. High engine idle speed. 2. Improper adjustment of the throttle cable or throttle position sensor, leading to excessively high main oil circuit pressure. 3. Delayed upshifting. 4. Cracked or loose vacuum hose of the vacuum-type throttle valve. 5. Malfunction of the main oil circuit pressure regulator valve, causing excessively high main oil circuit pressure. 6. Stuck damper piston, failing to provide damping effect. 7. Missing one-way valve steel ball, resulting in overly rapid engagement of shift actuators (clutch or brake). 8. Slippage of shift actuators. 9. Oil pressure solenoid valve not functioning. 10. Faulty ECU.
