Sometimes when I wait for the RPM to drop after starting the car, the engine noise is really loud. The sound gets louder or softer depending on how hard I press the accelerator, and the throttle doesn't feel as powerful as it usually does, requiring me to press it deeper. However, most of the time, this doesn't happen. After the RPM drops, the noise is normal.

Does your engine shake after the first maintenance? Mine is shaking quite a bit after today's first maintenance, and the engine noise is louder than before!

Fault code P0504, currently gears 1, 2, 3 are fine, but when switching to 4th gear, the car loses power when pressing the accelerator and doesn't accelerate. The RPM drops very slowly when pressing the clutch. Has anyone else experienced this?

In normal mode, when coasting after releasing the throttle, the car jerks when the speed drops to 5 KM/h. Is everyone experiencing this too?

When driving, if the car suddenly doesn't respond when you press the accelerator, and even flooring it doesn't increase the RPM, but releasing and pressing it again solves the issue, this could be a problem. When starting on a steep slope, if the car feels powerless and sometimes can't climb, requiring several attempts to increase RPM, there might be an issue to address.

Hello everyone, could someone help me with this issue? When in Park and idling, if I rev the engine above 1600 RPM and then release the throttle, the RPM stays around 1600 for about ten seconds before it drops. This doesn't happen if I don't exceed 1600 RPM. Between 1600 and 2000 RPM, there's a noticeable jolt. Additionally, when shifting gears and slowly accelerating, there's a rattling noise between 1600 and 2000 RPM, but it disappears after 2000 RPM. Does anyone have any insights on this? I would really appreciate it. The car model is a 2016 30T two-wheel drive. Thank you very much!

Has anyone else encountered this issue? Recently, when I activate the auto hold, after the car stops, the AVH light blinks and then there's a clicking sound. It happens every time. If I press the brake harder, the sound is louder; if I press lightly, the sound is softer.

After changing the drive shaft of a 12-year-old Korean imported car, it makes noise when you press the accelerator, but the noise stops after 2000 RPM. Fellow car enthusiasts, have you encountered this situation? How did you solve it?

Has anyone experienced the issue where the RPM doesn't drop after releasing the throttle on a Cayenne? Looking for solutions. 🙏

When lightly pressing the accelerator at low speeds, there's a slight jerk, and when the RPM drops below around 1100, there's a dragging feeling. What could be the problem?
