Via the the push buttons at the end of the wiper arm (can't remember which) scrolling up or down and then the push the reset button underneath is what you use to access any given mode.

I do have CANbus module for my Nano and my ecu does have CANbus support. I'll look into this, maybe it's better to jump straight into CANbus stuff. Oil pressure and temperature readouts must be taken directly from sensors anyway, but that's just using two inputs on Arduino.
BTW if it would be me, I'd use monochrome red/orange display for it to not stand out from everything else in dashboard. Subtle interior modifications are the best IMHO.

Yes it is, at least most of the functions. What is possible depends on information we can get from our cars and mostly on programming skills. On our cars we can read various temperatures, pressures and speeds directly from senders and convert them to values to display (as senders are giving out variable voltages or impulses per second not temperatures, speeds e.t.c.). Actual gear can be calculated from road speed vs engine rpms, oil level is impossible because there's no sender (unless you have swapped 1.8t, 2.7tt, 1.9TDI or something like that with oil level sensor in oilpan). Diagnostics as well as reading off various values also might be possible over K-line, but I haven't got that far yet, I'm starting with easier things to learn Arduino programming. On newer cars (or engines) you can read various information off CAN bus (what's most likely done on that A2).

We are slowly putting '04 AWM into B4 and I have no idea how to display fuel consumption because fuel consumption on AWM comes to dashboard via CANbus. It was no prob on B4 with '99 AEB (distinct f consumption signal from ECU) but what can be done with later Motronic here?

Just wire it up and see if it works. I'm not at home at the moment, don't have wiring diagrams at hand, but take APU engine for example, pinout is the same on all motronic ME7.5 ecus. Later B6/B7 has ecus with different CPU, don't know about these, but I wouldn't be surprised if there's separate fuel consumption output, just not wired up, haven't got my hand on later ecus. I'm also using B6 ecu (don't know engine code and part number), flashed with AWT software and fuel consumption output is working.
If you have any questions about 1.8T swap, I'll be glad to help. I have fully working drive-by-wire wideband Motronic ME7.5 setup in my car.

Wow wow wow, that's a promising info about dedicated 7.5 ECU signal chance!
One throttle-cabled car with my loom has been successfully running since last winter already. Hopefully, we will fire up the second car with throttle-by-wire this winter. I have made the engine loom in August, but guys have been postponing engine works for hundreds of reasons since that.
