Trying to adjust mileage on extra 2004 Bosch RB4 cluster I'm trying to swap in. Using Tacho Universal with 24C0X board and clip. When trying to adjust I get "Data Not Equal...Adj Clip". I'm putting the exact old value (in KM) and new value (in KM) as adjusted by the tool. What am I doing wrong? Any word of advise would be greatly appreciated. Tom

I was able to get a pin (40245) with the tool conencted to the car. The current mileage in km reads 101,488.. trying to adjust to 126,064. Still unable to change.

Attached file and PMd. Thanks.

Your dump is corrupted. Check file size.
Pin of such dashes has 4 digits with first "0". Yours login is wrong. Get it from ECU.
Upload attached eeprom file (it's exactly the same) and adapt dash and keys. Then correct mileage.

Will not work If you write this dump to dash you will get DEF and pin will be also wrong.

This is crypto dash

Hmmm
you have oryginal Good file ?
If you have , please write it in dash and check results ...
When display say : deff ...
You have a big problem .

This file i got through OBDII from the same vehicle using original VAG K+Can commander. After writing new eeprom disregard "def" message and disconnect negative wire from main battery for a minute. Then proceed with dash adaption like described in thread http://www.digital-kaos.co.uk/forums...h-dump-102724/
What does it mean "pin will be also wrong" ? This dump has fixed pin 00212.
I know that RB4 crypted and mask in CPU.
Let owner to try. He, always, can put back his corrupted file.

Thanks all for great help. Will try and update. How can one get the bin file from Tacho Universal to computer? Tried via serial interface and Sync option (Tacho Universal) then Hyper Terminal via COM1, but can't connect any get anything. There aren't any instructions how to sync.

You need tachodump software to communicate with tacho universal. Connect your box to a null modem cable, press sync on box and start tachodump, press options set com port, then connect.

This software for Tacho

Thanks Alex. Is there a way you can modify your original file attached above for 78,3xx miles (not sure how that would tranlate to exact km coded in) so that I can flash to eeprom and not modify further? I'd greatly appreciate.

[Alex789]

Sorry. It's possibly by OBD only.

[NogaroB5S4]

It appears that the adjustment won't be possible via Tacho 2008 Universal. Unable to read/write the crypted EEPROM through the tool and 24C0x interface. Ordered VAG K+Can commander tool to perform via OBD2. Thanks all for help.

Sorry what's the problem with the dump? It's perfect, cluster is RB4, made 11-09-03 D37 AUZ6Z0C0290585
Mileage about 100000 km (crypto).

Dr Peter,

I need the PIN from the cluster to change mileage with VAG Tacho 2.5. I was able to retrieve pin with Tach Universal, but not sure if thats correct: 9D35 - 40245 (correct? Can you confirm?) is what I got for the PIN. When I enter the PIN under Pass2 for VAG Tacho it takes, but when adjusting mileage it states: unable to calculate kilometers and fails. So not sure if it fails because of the wrong PIN or something else.

Also...i was going to adjust the original dump file mileage to 126064km and rewrite eprom, but can't even do that with VagTacho and above PIN. I was also trying to write EPROM (also with VAG Tacho) with the file Alex posted, but it fails to write stating not allowed or something similar. Which part of data from the dump is responsible for the mileage?
