In this video, we will see the symptoms of poor transmission control: firstly, the vehicle takes longer to gain speed, and the transmission changes gears unexpectedly without your input. Additionally, you may find it difficult to shift out of neutral; you cannot upshift during acceleration or downshift when you want to stop, and your car consumes significantly more fuel than normal.

In this case, what you can do is reprogram the TCM module; through this operation, you can restore the transmission control to its optimal state and bring the vehicle back to full performance. Naturally, this can only be done by a specialised workshop.

How to Reset the Tire Pressure Light on a MG ZS?

On the instrument cluster of the MG ZS, the tire pressure light that appears can be reset by inflating the tires to the correct pressure: this value will be indicated on the sticker attached to the driver's door pillar. Once the tires have been properly inflated, you can turn on the instrument cluster and navigate through the menu until you find the option that indicates tire pressure: if this screen shows the new values, the light will turn off; otherwise, you will need to drive for a few miles so that the sensors can read the new values and turn off the light afterward.
