Lots of people in here use an OBD Bluetooth adapter and matching phone app. There are also wired OBD devices with a presentable design to mount on the dashboard. You can get them off Amazon for less than €50.
It is something like this?

I did just a quick search for OBD bluetooth in the shops from my country, maybe I can find better deals, but it does not seem that expensive.
