It often happens that your air conditioning no longer cools; here’s how to recharge the air conditioning gas on a Volkswagen Jetta. Open and lift the engine compartment of the car, then locate the low-pressure valve (as shown in the video).

Connect the gas recharge valve to the appropriate hose: check the gas pressure with a suitable manometer. After recharging, unscrew the valve from the hose and screw in the canister containing more gas (as shown in the video).

At the end of the maintenance, check the proper functioning of the air conditioning (activate the controls) inside the car.

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.
