Are the glow plugs on your A-Class damaged? Let's see how to replace them. Pull the hood release lever and lift the hood, securing it in place.

Remove the soundproofing panel covering the engine head, then pull out the coils. Use a socket wrench to remove the glow plugs, taking them out of the head one at a time.

Take the new glow plugs and guide them into the engine head with the socket extension, then screw in the glow plugs. Reattach the ignition coils and install the engine cover panel.

Start the vehicle and test the operation.

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.
