The Head Unit 07 in VCDS is in two parts basically, the module behind the glovebox (4E0 907 468 A) and the buttons (4E2 919 610 B) in the centre console. BOTH need to work for the MMI to show.

From reading on the net the general consensus seemed to be the buttons were just buttons and them being dead just meant the MMI would work, but you wouldn't be able to use the buttons to control it. THIS is wrong. Unplug the buttons and the MMI shows for a few secs and then turns off.

Which is why i bought a second-hand HU (4E0 907 468 A) and was preparing to defeat CP, but my new module didn't show either, so i bought some second-hand buttons (4E2 919 610 B) which the MMI popped back into life.
I had the kit and was curious if I could remove the CP on the HU module with the eeprom write hack and it WORKED!
