Is there a definitive guide to component protection?
 

Is there a list anywhere as to what has component protection on a D3?

The following page has a list of components that have CP:

http://www.audi-resource.com/componentprotection.php

I've copied the relevant text to here just in case that page disappears at some point in the future:

Which modules have component protection

CD changer
SDS module
MMI controller
Can Gateway
Amplifier Modules
Driver Identification module
Air con control
Instrument Cluster

Modules without protection

Radio module
DAB radio
TV tuner
Navigation module
AMI
BT modules
SAP modules
Parking Controller

Thank you that's brilliant. Do you know if the MMI controller is part of the buttons or separate?

I think the MMI controller 'is' part of the centre console controls, assuming we're talking about this item:

If yours has a buttons problem, then you could just swap out the circuit board, as from the posts I've read, that's what has the CP on it.

Yes that's the bit I'm talking about. Buttons are fine (so far), but may play around with a different one at some point so wanted to know if it triggered CP.

Not sure about A8, but on C6 A6 you can get aftermarket Chinese buttons and fit them without triggering CP. MMI controller is a separate box. I would suspect A8 is the same but cannot say for 100%

A8 mmi cp is in the ecu behind glovebox,i have swapped cp eproms to avoid triggering

Great, thankyou. This means the buttons and board for them around the gear lever can be changed without any CP. +++

Yes they can be swapped over
