The 1.4T model keeps showing a fault light, and there's no 2nd, 4th, and 6th gear. The computer, valve body, and clutch have all been replaced, but the issue persists. How can this be resolved? Has anyone encountered this?

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?

When driving the 2017 1.5T Smart model at 55 mph, the engine makes a roaring noise, but it disappears after accelerating past 60 mph. I've cleaned the throttle body, removed carbon buildup, and changed the engine mounts, but the issue persists. I've heard that reprogramming might help, but it carries some risks. Has anyone encountered this problem?

In the 2019 JETOUR X90 Enjoy Edition 6-seater with a 6DCT dry dual-clutch transmission, currently at 120,000 kilometers, an issue has been occurring since around 90,000 kilometers. When starting the car cold, everything is normal during acceleration. However, after driving for about half an hour and the engine warms up, when stopping or waiting at a traffic light and then trying to accelerate again, the car doesn't respond to the throttle. If you press the throttle harder, the engine stalls. When you feel the engine shake while pressing the throttle, if you release the pedal immediately and then press it again, the car can start moving, and everything works normally after that. There are no fault codes detected by the computer, and the spark plugs have been replaced. The engine checks out normal at the 4S shop. I'm seeking advice from experts on how to resolve this issue or if any fellow JETOUR X90 owners have experienced a similar problem and how they got it fixed. Thank you very much for your help!

The battery of the JETOUR X95 is dead, and the remote key buttons are not working. After jump-starting the car, the emergency braking system activated. The car can drive normally, but the dashboard is only partially functional, as the idle speed and speed are not displayed. I tried to reprogram the keys because I have four keys, and the previously working key is not functioning anymore. However, I'm unable to successfully reprogram the key, and now the car won't start. Has anyone encountered this issue before? How was it resolved? This is the 2020 JETOUR X95 dual-clutch version.

What could be causing this issue with the 2011 Volvo C30? When shifting to 2nd gear, the engine makes a buzzing noise. There are no fault codes, but there is a throttle body fault code for the engine.

Why has there been frequent gear lag recently? It's a 2019 model with a 1.4T dry dual-clutch. After picking up speed and then braking, the gear doesn't match the speed. For instance, it's in 6th gear at 45 km/h and 5th gear at 35 km/h, but it doesn't downshift further. It upshifts quite eagerly. Went to the 4S shop, and they said the engine isn't strong enough, and the gearbox can't be adjusted?
