Don't know direct answer to your question, but it may be that clusters are not directly replaceable because of difference in engines, gearboxes, etc. They **will** have different software versions and God knows what errors you can expect in future...
If you're doing this swap only to renew overall condition of your current cluster please consider putting both clusters on the table and transplanting 'glass', dials, displays and other cosmetic stuff to your cluster from donor, leaving your native cluster electronics in place. There are writeups on internet how to open audi cluster and transplant basic stuff. If you need help with desoldering/soldering tired displays etc. there are plenty of people who can help you with this for cheaper than going to Audi with coding immo questions.
