Ok, here's something to play with (source)
Channel 018: Start Screen
0 = Standard Start Screen
1 = Audi S3 Start Screen
2 = Audi S4 Start Screen
3 = Audi RS4 Start Screen
4 = Audi TT Start Screen
It doesn't seem to work with my US 0150 software, maybe someone with the Euro software can try this out and report back if it works. Please note that after changing the startup screen you will need to reboot the RNS-E (save a value of 1 in 111 or hold RADIO and SETUP until it reboots).
First check you have EU SW 0500 or 0550, it won't work with older software.
To put it even more simply:
Using VAG-COM open address 37 or 56 (the RNS-E), select Adaptation, choose channel 18, and save the value you want as per the table above.
Then restart the RNS-E either by putting a value of 1 into adaptation channel 111, or by pressing and holding the RADIO and SETUP keys together until the RNS-E restarts.
