Accessing the power steering reservoir on the Volkswagen Polo 9N is anything but obvious, as it is located in the engine compartment, beneath the battery. It is a tank with a green cap, mounted directly on the side of the power steering cylinder, found at the rear right of the engine compartment, underneath and behind the battery group.

We start by disconnecting the battery, always beginning with the negative terminal. Next, we unscrew the battery hold-down bolt, which is quite heavy (about 20 kg). We firmly grasp the battery by the designated handles and lift it upwards.

Underneath the battery, there is often a plastic tray secured with clips, which we will need to detach. The reservoir is cylindrical, and depending on the version, it is either made of metal or black plastic, with a large green screw cap connected to the steering pump by a hose.

To top up, we should only use the fluid specified by Volkswagen, G 001 000, known as Pentosin or CHF22S; we should never use ATF, which is the generic red automatic transmission fluid that would damage the system.

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.
