Well, it's not really a secret - it is in the Bentley repair manual - at 
least for the US and Canada and Saudi Arabia (???) - UrS4 ... for the lucky few 
with the display.

aF = Multiport Fuel Injection

- run the engine at 3000 RPM for 30 Seconds.
- Switch Engine off
- Press and hold Reset
- Switch Ignition On (while holding reset)
- Press lower function selector switch and hold down
- aF should appear

2 has the following code
a411 = code for 5 Cylinder ... USA and Canada ... (what happened to Saudi)?

3
is not listed in the manual will have to try.

4 
US, CA or SA

5 
Same


... and trip computer range can be calibrated.
