Anyhow I thought I would circumvent them and buy the two updates I need, 0614 and 0770, but they won't sell me them, stating they are service tools not for general sale, so I am snookered.

I ordered 2 CDs and 1 SD card from my local dealers and followed the following process -

0518 - 0612 using CD 8R0 906 961BT
0612 - 0614 using CD 8R0 906 961CD
0614 - 0770 using SD 8R0 906 961DG

I did one update at a time with a journey in between updates to ensure the battery didn't die on me, but you could connect a battery charger to negate the risk and do them one after another.

To start the process you need ignition on (engine not running) and I turned everything else off (aircon, auto-lights, etc.),
Then press together CAR + BACK buttons to access the Update menu. Brings up a RED menu.
Bottom right MMI button is UPDATE select this and it will then ask for media location - insert relevant media and select.
A list of updates will appear with Y, N or NA against them, scroll to the bottom and select UPDATE, allow the process to run to completion - don't worry when system reboots and comes back in German, it will reboot again into original language.

The above part numbers are relevant for MMI 3G+ in the A7, A6, A8 & Q3 according to the link below which also includes part numbers for other models and MMI versions globally.

I don't confess to being an expert (I've always updated my own MMI software on the 4 Audis I've had with no problems at all) but I followed the above steps with no problems at all please use at your own discretion

Thanks!
