According with gruodiz, did you tried now, after updating software in the cluster?

@gruodiz
Did I understand correctly from the lr-club.ru, is this language selection on the cluster has something to do with the language on the audio system?

NO, I did newer version software download and then the option in SDD service menu, language selection work fine when selected Russian language.

After that I did it English again as I don't understand Russian a lot

I have not tried any more, if I have time I will hook up and try later today. JLR136 now on a test laptop.

I have a request to make NAVI system speak Russian and that menu in Russian as well. Will try some upgrades there too. My client told me that this option is available in Russian market so if that is true it's just a software question

Just did the downgrade of instrument cluster to the very first (factory) stage, checked all functions worked fine, engine running, no errors and then upgraded again.

I can confirm that program lets to do upgrade and downgrade as well

Do you, any of you that have an instrument cluster on the bench, have the possibility to open it and tell me which is the part number of the microcontroller inside? The "brain" of the IPC? We may try to look at the code and who knows, maybe activate other things too.
At a quick look inside, there are messages even for programming the webasto for starting at a predetermined hour...

here you go!

Thank you very much!

So the core is a Fujitsu MB91F013...
 

I flashed my IC with the newer firmware.
I have a MY2009 so things are a little different, at least from their point of view, on MY2009 than on MY2007 like yours.
For example I don't get the error:
U0300 Internal control module software incompatibility
but I always get this error from the Instrument Cluster:
B1A84-81: Vehicle configuration data, bus signal/message failure - invalid serial data received
Probably it sees that the VIN is out of its range, the firmware being for MY2010 and later and the VIN contains info for a car from MY2009.
Otherwise, it seems that it's functioning OK.

hello,

I have a problem with the instrument culstuer of my Freel2, 2007, TD4, 160cv
Helped with a freind we tried to update th firmeware , but something goes wrong and now my instrument cluster did not works well :
les LCD screen is always empty (nothing is displayed)
the millage is displayed in miles , in the past it was displayed in Km (frensh car)
when I forgot the seat belt , no sound warning ...

can some one help me to understand what happen and help me to solve this problem
may a good flashing solve the problem ?
any idea ?

thinks in advance

Hi!
Have you tried a standard flash under "Service Function" and "Configure new module" on the instrument cluster?
I would think that should fix it, even if you got an error the first time - try again.

Another flash of software in Service menu should work as well as upgrade I wrote in first post.

Hi,
could you give me the correct method to flash it into the new config,
- exact file (where to download)
- software to use ?
...

is it possible to flash it without disassemble the cluster ? (using the diag cable or other interface ?)

regards,

The previous users have already given you the method....

Reading your words, maybe you could tell us how you and your friend flashed the instrument in order to form an opinion of what happened there?...

what I remember is the freind disassembled the cluster and removed one shipset (or memories part)
he flashed it using an programer software (I dont know the exact software)

the problem is the freind moved from our city and he can not help me anymore, so I have to solve the problem my self, and I dont have a good skills in these method, and I dont have any software

thanks for Ur help

regards
