Hi!

From the readouts in various software Im 99% sure its a Bosch Cluster. I havent yet pulled it out and cheched.

Thanks,

Bjorn

?? didn't work for you to log into either the ecu or the cluster?

if neither, then I'm concerned that you aren't entering the pin into the correct field. (it happens more often than you'd think)

ECU:
[Select]
[01 - engine]
[LOGIN - 11]
enter five digit pin into the LEFT field
[DO IT!]
...same as first twenty seconds of this video

CLUSTER:
[Select]
[17 - Instruments]
[LOGIN - 11]
enter five digit pin into the LEFT field
[DO IT!]
...same as first ten seconds of this video

I tried the PIN in ECU login and it works ... not sure what use I have of it in my case but it proves that the extraction tools works just fine.

About the cluster make I have attached some pictures. My guess its a Bosch cluster. A strange thing is that the info in the Extra field has changed since my first efforts to try and learning keys. Im 99,99% sure that the first part of the info in the Extra field used to contain only 0-9 characters. It looks messed up now. I also went out to read out the bin from the Cluster again and when comparing the files in a hex editor some of the info has changed for sure.

See attached files. Sorry for complicating the original question but theese things tend to grow and with it the stubburnness to actually solve the problem.

Known facts so far:

The ECU PIN is 06403

The Cluster PIN is not 06403, 01010, 04112 or 39584


Update: I attached the screendump from VAG CAN Commander v2.5 and it suggested the PIN 39584. Not working either.


Thanks!

Bjorn

whether on this site or others, the more I read about the bosch encrypted clusters, the more I'm finding that they don't play well with cheap clone tools, even if they're only being read.

Thanks guys!

I certainly have been warned and I appreciate both the warnings and the other help from you.

As stated in the first message I bought the car in this condition and I think the cluster might have been damaged to start with. The car was bought from an auction site and the description stated "key cannot be programmed with the car". Possibly some workshop has already tried to do this with good or bad tools. I bought it with the target to replace the cluster if it cannot be saved.

From this point I have a couple of options.

Replacing the cluster with a used one  (I will need the PIN along with the cluster)
Replacing the data with a working flash (desoldering the flash ?)
Bring the car to an Audi workshop and let them do all the work. (expensive and my project dies)
Kill the Immobiliser part in the ECU (out of my knowledge)

This will be a new thread for sure but replacing the data in the existing cluster will be the most fun I think .. Second best choice is to modify the ECU to ignore the Key issue.

The car still starts for a few seconds so even if I have messed up the cluster further my guess is that it still works as bad or good as before ?

Any bright ideas ? 

And also - can we for sure say that getting the PIN out of a RB4 encrypted (this one is encrypted ?) cluster is impossible ? If yes, any used cluster from the junkyard is a bad idea if the PIN is missing.



Thanks,

Bjorn

F1torrents is the guy you want to talk to. He has the real deal cluster tools and can do rb4.

However, I'd just defeat the immobilizer and remove the LED. It's really not that hard.

Just post your read, someone here will turn it off for you.
