Hidden Menu
 

On the Range Rover you can access a hidden menu on the instrument cluster that will give the list below so just wondered if the A8 had anything similar

1. Display Car's identification number, HW/SW version, construction date
2. instrument cluster self test. Will light up all lights and run all guages
3. Current consumption (liters/hour)
4. Average consumption (liters/100 km)
5. Current range
6. Remaining fuel in tank. Three sets of numbers: A/B/C. C=total amount.
7. Engine RPM / Coolant Temp (C)
8. Current Speed (kph)
9. System voltage at Term. "R" (Battery Voltage)
10. Country/Language (UK, US, Spa, Ger, Jap, etc.)
11. Units am/pm
12. Average Speed
13. ETA
14. Date of Software Mask
15. Production Diagnosis
16. ""
17. Display Vehicle Specific Data
18. Alarm Changeover (cont. vs. intermittent OBC chime)
19. Lock/Unlock
20. Correction factor for fuel consumption (nicht ändern!)
21. Reset all defect codes

Most of that needs VCDS.. There is some stuff that can be done from the hidden menu, but not a lot really, more dealer diagnostic type things.

Thanks +++

You press CAR + SETUP at exactly the same time and hold for a few seconds until a green hidden menu appears. It is all in techno-cryptic German, but is rather different from the Range Rovers in that it can be used to enable various options, some require additional hardware such as TPMS and oil level, others (such as adjustable ambient lighting) don't.

Thanks snapdragon, I might have to learn German before venturing into that

Though it's not always enabled (or at least in earlier versions of MMI).

If you do look in there, never press START BOOTLOADER:tuttut:

Is that the voice of experience?

But yes.. Never, ever click it!!

Thanks to all who replied but I think I'm going to not touch it, too much to loose

Trouble is. . . now youve told him not to press it he will really really want to. . . :D
