Reasons for Severe Jerking During MG6 Startup
5 Answers
The reasons for jerking during MG6 startup include: 1. Clogged engine oil passages; 2. Dirty transmission oil clogging the oil passages; 3. Damaged transmission solenoid valve; 4. Forgetting to release the handbrake; 5. Irregular wear of the clutch; 6. Damaged solenoid valve; 7. Some engine cylinders not working; 8. Poor volatility of low-quality fuel. Solutions for jerking during car startup: 1. Check the transmission temperature and cooling system; 2. Replace the transmission oil; 3. Inspect the internal valve body of the transmission for damage and replace if necessary; 4. Check the engine valves and intake manifold for carbon buildup that needs cleaning.
After driving the MG6 for a while, I noticed the annoying jerkiness during acceleration. Common causes could be transmission issues, especially with the dual-clutch design, where the clutch plates don't engage smoothly or slip during low-speed gear shifts, causing noticeable shaking. Additionally, improper engine tuning might be to blame, such as turbo lag or clogged fuel injectors, which affect acceleration response. I think carbon buildup is also a key factor—a dirty throttle body reduces air intake, making starts less smooth. In daily driving, try gently pressing the accelerator to avoid sudden acceleration, or schedule regular check-ups at the 4S shop to clean carbon deposits and change the transmission fluid, which can significantly reduce symptoms. Safety first—don't let small issues turn into big problems.
As someone who loves studying cars, I've pondered the MG6's jerky start-up multiple times. This car uses a dual-clutch transmission, and its low-speed gear-shifting logic is prone to errors, such as delayed responses from the control unit or unstable pressure in the hydraulic system. Another angle is the engine system—aging spark plugs or faulty ignition coils can lead to poor ignition, causing acceleration to be erratic. Sometimes, interference with the throttle sensor signal can also cause this. It's advisable not to skimp on regular maintenance, performing an intake cleaning annually and checking if the ECU software needs updating. Replacing spark plugs or upgrading the transmission program might yield good results.
The cause of jerking is usually related to transmission or clutch issues. In the MG6 automatic model, dual-clutch wear is common, while in manual models, clutch slippage often occurs. Ignition system failures, such as excessive spark plug gaps or damaged ignition coils, can affect engine power output stability. Excessive carbon buildup leading to uneven air intake is also a potential issue. Inspecting these components and replacing or cleaning them when necessary can resolve rough starts. Don’t forget to check fluid conditions, as old transmission oil can increase friction.
From a maintenance perspective, starting hesitation mostly stems from ignition or fuel system issues. Worn spark plugs or aging high-voltage wires causing intermittent ignition can lead to hesitation during acceleration in MG6 engines. Insufficient fuel pressure or clogged fuel injectors disrupting the air-fuel mixture ratio can also cause this. It's recommended to regularly inspect these components, replacing spark plugs and cleaning fuel injectors every 20,000 kilometers. Using high-quality fuel additives helps reduce carbon buildup. Transmission fluid should also be changed on schedule to ensure smooth gear shifts and prevent hesitation.
