Video tutorial

In this video, we are shown a fairly common fault on the automatic gearbox of the Mercedes A-Class W168: when we turn on the car's instrument panel, we see that all the lights come on normally, except for the one indicating the gear currently engaged, such as "P" or "N" and not even "F" which could indicate a malfunction in the automatic gearbox.

The car works perfectly, but while driving, it goes into "F" and doesn't move anymore.

We try to pull over, turn it off, and sometimes it resets and starts again, but after a few kilometers the fault reoccurs. The problem lies in the burned out control unit, which is not repairable; we must therefore replace it, and it is not a cheap part.

We can find it for example on Ovoko with the code a0335450032 at a price of 450.00 euros + shipping costs.

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.
