The solutions for the jerking sensation in the Audi A6L are: 1. Clean the sludge inside the transmission; 2. Clean the throttle body. Taking the 2021 Audi A6 as an example, it belongs to the mid-to-large-sized car category, with body dimensions of: length 5038mm, width 1886mm, height 1475mm, wheelbase 3024mm, and fuel tank capacity of 73 liters. The 2021 Audi A6 is equipped with a 2.0T turbocharged engine, front suspension as a five-link independent suspension, rear suspension as a five-link independent suspension, maximum horsepower of 190PS, maximum power of 140kW, and is paired with a 7-speed dual-clutch transmission.

I've driven an Audi A6L for several years and experienced jerking issues, especially noticeable during low-speed gear shifts. Later, I found out it was caused by aging dual-clutch transmission fluid. Over time, transmission fluid deteriorates, affecting smooth gear shifts. It's recommended to change it every 60,000 kilometers. After replacing it with genuine fluid, the jerking sensation almost disappeared. The process is quite simple, but choosing the right fluid is crucial. Additionally, engine sensor issues can also cause jerking, such as a faulty mass airflow sensor leading to uneven fuel supply and shaking during acceleration. I regularly clean the air filter and throttle body as a preventive measure. In short, handling it yourself can save some money, but don't overlook checking clutch plate wear, which is common in older cars.

I usually pay attention to car maintenance, and I feel that the jerking in the Audi A6L mostly comes from the transmission or driving habits. The transmission needs regular maintenance, such as checking the oil level and cleaning the shifting components to avoid clogging due to dirty oil. In terms of driving, avoid slamming the accelerator; gentle acceleration can reduce jerking. If it's an older dual-clutch model, sometimes the ECU software not being updated can also cause jerking—just visit the dealership to update the program. Additionally, aging spark plugs can affect ignition smoothness. I replace mine every 50,000 kilometers, and the car runs much smoother. Remember to warm up the car before driving, especially in winter when jerking is more likely to occur. Prevention is more important than repair.
