Dongle for code reading & coding

On my old fabia I used to have an ultra gauge plugged in

Which allowed me to read some data and any engine lights and clear them

I used carista to code stuff like alarm beep, lane flash, MPH etc

Now with the superb

I would love to code a few things

Maybe headlight DRL stripes, maybe rear DRL on

And alarm beep to name a few

But I really want to be able to read any codes that come up, need a half decent code reader

To be able to read any future issues

Any advice please
