What could it be?

It is very likely that component protection active is present on one or more modules due to different reasons.


What is component protection?

For security reasons some modules built in the VAG implement “Component Protection”. This strategy is to prevent exchange of modules without central authorization from the VAG online database (dealer visit).  Such modules installed in another vehicle activate the “Component Protection Active” DTC and are with restricted functionality in that vehicle.

Required when a replacement used/donor module, such as Instrument Cluster, Ezs/Kessy/Steering Lock, HVAC Control, MMI Control Head, Comfort/Convenience Module, CD Changer/MP3, Power Seat Memory, etc is installed in a vehicle it didn't originally belong to, failure of  performing software update or it can be triggered by even a flat battery.
