My MMI failed for the second time in 2 years. The MMI board itself is actually fine, it's the module behind the glove box that's actually failed. I've copied a pic for reference (it's part #1). The install process of the unit looks fairly easy, but my shop was wondering if there was any coding beyond the install? They inquired about a Workshop Code - what is that exactly? I'm simply in need of details of what needs to be done with VAGCom to complete the entire install process?

Part # is: 4F0910732QX
Attachment 104766

You will need to visit the dealer, the Gateway is part of the Component Protection which can only be learned at the dealership.

Dammit.

Did you get this resolved without going to the dealer? The diagram(number 1) shows the control head not the gateway.

I've got a new Control Head on the way as the MMI in my D3 A8 was cycling on and off every few seconds and a VCDS scan showed electrical and optical errors with the Control Head. While diagnosing my issues I disconnected the Gateway(located right next to the Control Head in the A8) and the car wouldn't even stay running when I left the Gateway unplugged.

What is being referred to here? "The MMI board itself"
[people need to be as explicit as possible - was explicit about identifying the "headunit" - but not the "MMI board itself"]

My MMI will not turn on although the is power to all components - CD, NAV-DVD, AMP, comtrol panel and presumably the display.

My diagnostics say it is the "CAN Gateway"
Exactly what part on the diagram is the "CAN Gateway"
Number 1 is the "headunit" or "MMI Interface box/module"
Last poster said it is beside the "headunit" - which number on diagram or is it not on the diagram?

Also, what is involved in reseting the system is a "protected" component is replaced?
