Some of you may have seen my other thread about swapping clusters in an 01 Allroad.  I'm trying to get rid of my flashing immo light w/o having to buy new key rfid pills.  I was told that I could copy the information from my old cluster dump, to my new cluster dump... then flash it to the new cluster and be done with it.  But I can't find any specific information about the location of this data in the cluster dump.  I saw the other thread where f1torrents helped someone do the same thing, but he did it for them and there was no discussion of data addresses.  I can diff his two files and see what he changed, but that was for a different cluster than mine and I want to be sure before I brick my new cluster (that actually has a working MFD!)...

Except I was already told by someone that that will brick the cluster.  And I've seen your thread where you bricked someone's cluster.  So I'll wait for the actual information, thanks.

If you can't answer the question being asked, maybe you can just not give out bad information... I've seen multiple threads where you were told this is not a good idea... about how there are multiple encryption keys used to pair the MCU, and if they're mismatched you will brick the cluster.  Just stop yourself, get over yourself, move on.

Sorry, If thats what daz said its gold and this is why... Lucky for me I had the same one

With the GLI clusters you can do this, but you will get a DEF error. That can be cleared if you recode because the cluster will recalculate the checksum. HOWEVER, this doesn't appear to work on the 02+ A6 clusters.

It won't brick it (flashing a file with a bad checksum), so if you have the eeprom of the ecu we can try it, but I need to see the ecu eeprom in order to identify the data needed in the 01 cluster.

What I would suggest is installing the new cluster, then adapting that cluster to the ecu. After that, the new cluster will have the same immo ID as the old one, and key matching used keys won't be an issue.

As for bricking, I am beyond certain that flashing the 01 binary to the 04 cluster will SUPER brick it. I have done it, I have fixed the problem for others that have done it. It is a shitty job.

Your old (cluster) pin is 02300 (and by association, that is your ecu login as well)
Your new (cluster) pin is 02083

That is all you need to adapt. If for some reason the 04 dash won't accept the pin, we can reflash a NEW compatible bin to it, then try again. My advice, download teamviewer and let me take a wack at it. Send me your user ID and PW in an email if you'd like to do it

And what I'm telling you is that without a method of correcting the checksums, your dash will read DEF. This isn't the mk4 where you can simply recode to fix them. The proper way (and the way I would have done it if we had teamviewed) is to re-enable the immobilizer by flashing the correct file to the ecu. After that, pair the NEW dash to the OLD ecu. That will keep the immobilizer ID that the keys have been matched to so that they can then be rematched to the new cluster. After which, flash the ecu with whatever you want, it'll all be paired.

The lock data is at 0x790, 0x798, and 0x7A0.

In your old dump it is:
87 A4 47 3C C4 71 76

The login code is at 0x7E2, 0x7E4, 0x7E6

In your old dump it is:
FC08

Then you have the vin and immo ID which is stored above it in an obvious location. Attached is the new dump, with the old immobilizer data. I haven't worked out the checksum routine yet, so this will likely read DEF. You can try recoding, or even reprogramming the mileage to see if the checksum is recalculated, but IDK. The standard disclaimer applies, I am not responsible for anything resulting from the use of this bin. With that said, I think you're safe to experiment.

Like I said, adapting it is the proper way to do it, but it seems as though you don't want to hear that.

All you must do is make sure to first adapt the cluster to the ecu, not the ecu to the cluster. The only time you have to worry about not being able to reuse the RFID transponders is if you don't have any of the original files.

As you have both the ecu AND the cluster, this is very easy. The only shitty part is like you said, there will be some games involved due to the incorrect flash being loaded onto the ecu currently.

BUT, it'll be fun-lol.
