It is about time I wrote this I think :smiley:
Let's get this bit out of the way, you perform this mod at your own risk, if you screw your cluster up don't blame me! Only do this if you are confident you know what you are doing :nerd:
Miles to empty on a VDO immobiliser 3 cluster. If you don't know which cluster you have then take a look at the cluster FAQ here (http://uk-mkivs.net/forums/t/167146.aspx) :afro:
To use this guide you will need:
1. An immobiliser 3 VDO cluster
2. Vagtacho software and cable (VT)
3. A Hex editor, I am using XVI32 available here (http://www.programmersheaven.com/d/click.aspx?ID=F21568)
1. Connect up your cable to the laptop and car then with the ignition on run the Vagtacho software (VT)
(http://i65.photobucket.com/albums/h208/old_n07/cluster/MTE/1.png)
2. If you know which cluster you have then you can skip this part and go to 3
Press Connect Any Tacho
(http://i65.photobucket.com/albums/h208/old_n07/cluster/MTE/5.png)
VT will return the cluster info and from the part number and type you can tell if your cluster is VDO and immo 2 or 3 :afro:
(http://i65.photobucket.com/albums/h208/old_n07/cluster/MTE/6.png)
Then click the disconnect button
(http://i65.photobucket.com/albums/h208/old_n07/cluster/MTE/7.png)
3. Select VDO new from the ECU drop down list
(http://i65.photobucket.com/albums/h208/old_n07/cluster/MTE/2.png)
(http://i65.photobucket.com/albums/h208/old_n07/cluster/MTE/3a.png)
And click on connect selected ECU
(http://i65.photobucket.com/albums/h208/old_n07/cluster/MTE/4.png)
VT will connect and return the following info
(http://i65.photobucket.com/albums/h208/old_n07/cluster/MTE/8.png)
4. Reading the SKC code (PIN number)
Press the read PIN button
(http://i65.photobucket.com/albums/h208/old_n07/cluster/MTE/9.png)
The SKC is returned by VT, to use in VCDS (Vagcom) put a 0 in front ie 03957
(http://i65.photobucket.com/albums/h208/old_n07/cluster/MTE/11.png)
5. Reading the cluster eprom
Press the Read button in VT
(http://i65.photobucket.com/albums/h208/old_n07/cluster/MTE/12.png)
(http://i65.photobucket.com/albums/h208/old_n07/cluster/MTE/13.png)
(http://i65.photobucket.com/albums/h208/old_n07/cluster/MTE/14.png)
When done File > Save
(http://i65.photobucket.com/albums/h208/old_n07/cluster/MTE/15.png)
(http://i65.photobucket.com/albums/h208/old_n07/cluster/MTE/16.png)
Save two copies of the file, one labelled original and one modified!!!
6. Editing the eprom
Close VT and open up the HEX editor XVI32 and File > open
(http://i65.photobucket.com/albums/h208/old_n07/cluster/MTE/17.png)
Open the file you saved with the modified label :afro:
(http://i65.photobucket.com/albums/h208/old_n07/cluster/MTE/18.png)
To enable miles to empty the hex address $416 needs to be modified, in a standard cluster the value will be C1, to turn on MTE change the value to E1
Click on Address > Goto
(http://i65.photobucket.com/albums/h208/old_n07/cluster/MTE/19.png)
Enter $416 in the box and make sure hexadecimal is selected > OK
(http://i65.photobucket.com/albums/h208/old_n07/cluster/MTE/20.png)
This will highlight the address value in the eprom file
(http://i65.photobucket.com/albums/h208/old_n07/cluster/MTE/22.png)
Click on the address value and type in E1, the blue selection will then move to the right and select the next value but don’t change this value.
(http://i65.photobucket.com/albums/h208/old_n07/cluster/MTE/23.png)
If you make a mistake re load your file into the editor and start again :afro:
To enable lit pointers the value at address $1ED need to be modified, in your standard cluster it will be 30, the value is changed to 3X where x represents the value in the list below:
x value
3 - displays only
5 - gauges only
7 - displays and gauges only
9 - needles only
B - displays and needles only
D - Needles and Gauges only
F - all lit up
39 is the most common choice but feel free to experiment :afro:
Click on Address > Goto
(http://i65.photobucket.com/albums/h208/old_n07/cluster/MTE/19.png)
Enter $1ED in the box and make sure hexadecimal is selected > OK
(http://i65.photobucket.com/albums/h208/old_n07/cluster/MTE/21.png)
This will highlight the address value in the eprom file
(http://i65.photobucket.com/albums/h208/old_n07/cluster/MTE/24.png)
Click on the address value and type in 3x, the blue selection will then move to the right and select the next value but don’t change this value.
(http://i65.photobucket.com/albums/h208/old_n07/cluster/MTE/25.png)
Once you have finished editing File > Save
Close the editor
7. Uploading the modified eprom to the cluster
Open up VT again and connect to the cluster as in steps 1 and 3 above
Click on File > Read file >
(http://i65.photobucket.com/albums/h208/old_n07/cluster/MTE/26.png)
select your saved modified eprom dump and this will be loaded into the VT memory buffer
(http://i65.photobucket.com/albums/h208/old_n07/cluster/MTE/27.png)
Click on write eprom
(http://i65.photobucket.com/albums/h208/old_n07/cluster/MTE/28.png)
Click on continue and VT will write the eprom back to the cluster
(http://i65.photobucket.com/albums/h208/old_n07/cluster/MTE/29.png)
Wait until Done
(http://i65.photobucket.com/albums/h208/old_n07/cluster/MTE/30.png)
Click on options > Reset Tacho
(http://i65.photobucket.com/albums/h208/old_n07/cluster/MTE/31.png)
And that is it, disconnect your cables :afro:
If you have any issues with the eprom write then you can try to put the original file you saved back onto the cluster, this is not always possible however and the cluster could end up dead :cry:
Hope that makes sense

Using the above methods change the value at $417, in a cluster without the Welcome message it will be 02, change the value to 6B to enable the message
This only works on a Full FIS VDO immo 3 cluster :afro:

Top stuff from the original clock master Neil :afro:

There are a lot of people buying the copy cables off ebay Rich, I just don't want someone to screw their cluster up by not knowing what they are doing

good guide neil, i would say its spot on.. i did this myself with help from yourself and others on ukmkivs.
i used a clock set from a passat but its all the same, the only difference is i had to upload a dump file from an anni to make it all work. the soft codings and everything had to be changed to get it spot on too. :smiley:

Just done this to mine, excellent guide!
Thanks Neil, you're a genius!

Thanks for the writeup, used vag tacho to turn in the mte and needles on my tdi anniversary today and all worked well.
HOWEVER! my rev counter now doesnt work :cry:, used VAG COM to test the instruments and everything works fine, then used the live readings on VAG COM to check siginal and all is ok here shows idle at 880rpm. I tried writing eeprom back to my saved orginal but still no rev counter.
Has anyone got any ideas where I may have gone wrong??
Thanks
Paul
