What causes the low-speed jerking in the Tayron?

The low-speed jerking in the Tayron is caused by the significant difference in gear ratios when the upshift gearbox changes the direction of the transmission gear. To prevent the dual-clutch transmission from overheating, the clutch engages in a semi-linked state, leading to low-speed jerking. Below is more information about the Tayron: 1. The Tayron is an SUV model under FAW-Volkswagen. 2. The Tayron is equipped with a CUG 2.0T high-power engine and a DBF 2.0T low-power engine, paired with a 7-speed dual-clutch transmission. 3. Based on the European version of the Tiguan and built on Volkswagen's MQB A2 platform, the Tayron adopts Volkswagen's new family design language. The front features a horizontal grille paired with LED headlights on both sides, effectively extending the horizontal visual width. The waistline extends from the headlights to the taillights, and the rear design is rounded and bold, with robust lines creating a muscular appearance. 4. In addition to standard features like 360° panoramic imaging, the third-generation intelligent parking assist system, and blind-spot detection, the Tayron also includes the TJA traffic jam assist system. Combined with ACC 3.0 adaptive cruise and Lane Assist lane-keeping, it achieves L2-level autonomous driving. The 4MOTION intelligent all-wheel-drive system offers four road modes, two off-road modes, and one snow mode for seamless switching.

As someone who frequently researches automotive powertrains, I believe the low-speed jerking in the Tayron may be related to the tuning of the dual-clutch transmission (DSG), especially when shifting to lower gears in congested areas—the clutch plate friction action isn't smooth enough, causing that jerky sensation. Additionally, if the engine ignition system is aging, such as increased spark plug gaps or severe carbon buildup, dust interference with the mass airflow sensor data, or slight clogging of fuel injectors affecting fuel supply, these cumulative issues amplify the jerking. While driving, try to press the accelerator smoothly and avoid sudden acceleration or braking to alleviate symptoms. Regularly visit the 4S shop to check the transmission fluid condition, clean sensors or the fuel system promptly when dust accumulates, and prevent worsening issues. If the transmission software hasn't been updated, upgrading the ECU version may also optimize shift logic.

I've driven the Tayron myself, and the low-speed jerking is particularly noticeable in city traffic jams. The car shakes like it's stuttering, which is quite frustrating. The main reasons are often the automatic transmission's design not being refined enough, causing significant shifting impacts at low RPMs, or unstable engine fuel supply. Too much carbon buildup in the throttle body restricting air intake and degraded spark plug performance also add to the trouble. Driving with slower acceleration helps—avoid sudden stomps or prolonged low-speed crawling. Simple fixes can solve it, like cleaning the fuel injectors and air filter every six months, and replacing spark plugs isn't expensive either. But if it's severe, it's best to have a repair shop check the transmission module—don't delay to avoid increasing the risk of failure.

Improper driving habits can easily cause low-speed shaking in the car, especially for the Tayron. Controlling the throttle rhythm and avoiding frequent acceleration and deceleration at low RPMs can alleviate jerking. Additionally, checking the fuel system is crucial, as clogged fuel injectors or sensor issues often lead to instability. Regular maintenance of transmission fluid makes a significant difference—simple and hassle-free.

Low-speed jerking is not just uncomfortable, it also affects driving safety. Sudden impacts may lead to potential loss of control hazards. For the Tayron, it is mostly caused by aged and thickened transmission oil affecting lubrication, or an imbalanced air-fuel ratio causing engine surging. It is recommended to perform timely maintenance, inspect the DSG unit and ignition components, and update the software if necessary. Developing smooth driving habits ensures both safety and extends component lifespan.
