Here is the back of the instrument clusters.


You can see the difference between all the clusters .

Cluster 1 was installed in 1998 and 1999 Audi A6 models, the most visible difference it had analog clock
Cluster 2 was installed in 2000 to 2003 Audi A6 models, the most visible difference it had digital clock comparing to cluster 1
Cluster 3 was installed in 2003 to 2005 Audi A6/Allroad from 2001 models, the most visible difference it had rings added comparing to cluster 2

NOW COMPATIBILITY
Legend

• * Cluster 1 is 1998-1999 (no immobilizer, no Can-Bus)
• * Cluster 2 is 2000-2003 (no immobilizer in 2000 model, Immobilizer was added in 2001, Can-Bus was introduced in 2000+ models)
• * Cluster 3 is 2003 to 2005 (had immobilizer and Can-Bus) Audi Allroads from 2001 to 2005 had Cluster 3

Cluster 2, and cluster 3 can fit directly into cluster 1, except the middle new plug needs to be installed and rewire connection.,
Cluster 3 can be installed into cluster 2 however it all depends if your car came with immobilizer.If your car came without immobilizer,
and you installed cluster that has immobilizer you will have little car key light ON on the tachometer , check the picture below.

This can not be disable by software, only solution is to cover with black electrical tape the opening for immobilizer light, only you will hear beeps for couple seconds when starting the vehicle.
If your car came with immobilizer , and you want to install another instrument cluster with immobilizer you need VAGCOM software from Ross Tech to program immobilizer to your car or you can have your Audi Dealer perform the service for you.
WARNING for those with immobilizer !!!
Do not start the car when you remove the cluster or when you install new one if it wasn't program to your car yet, if that happens your vehicle will start and shut down under 5 seconds and immobilizer will activate , at that point it will not allow you to start the car and you will have to tow your car to Audi Dealer to have them reset the immobilizer with their device

How do I know if I do or don't have immobilizer ?




ABS & Brake lights + AirBag Light on

Can you please tell me if i can use any cluster with an LCD and same conecter or do i have to only look after the same one i got? I went to Audi and the had another one to sell and it have this number 4B920933DX. So please help me if you can.

Best regards.

if you want to avoid it then better get cluster with 919 instead 920
