What causes the low-speed jerking in the Tayron?
2 Answers
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.
