Hey guys, hope all is well

Yesterday, a symbol came up on the dashboard. The only other time I've seen it is when my dad went on holiday, and asked me to start their car for a while periodically. I did so and noticed this came up, then went away after a few days (the car hadn't moved). Now it has also come up on my car and I'm not sure what it is. Anybody seen it before (image attached)?

Brake pad wear sensor. Time to change them

if it’s on all the time

I second that! Look through the wheels at the pads and see which pad is closest to wearing out and change that end of the car. Fronts I think carry the sensor on the b6 and b7
