Need help changing miles on an Audi A3 with VagTacho 3:01
there is a Marelli M73 v1.

It must be made manuel and I do not understand how I should do when, it in the first box says complete with HEX

Is it the login code it wants in hex ​​or?

Please explain to me like I'm 9 years old and a bit stupid.

I've used Google to translate from Swedish, but you probably understand what I mean.

Is there any other program that is easier to work with?

I have VAG K + CAN COMMANDER 1.4 that I use for my Audi A4 with
RBV
And full verision of VCDS

Please

Can you take a picture of the screen when it asks you what you cant complete?

I can not take a screen print, because when I press ctrl-alt-PRSC the box on Vagtacho disappears.
But it's the same red box as inputting PIN code for other cars, but it says write in HEX.

Make sure you are connecting to the right ecu/version.

If you can save the eeprom and post here. I can check if I find a solution for the file.

I solved the hex, it was pin code that would be in hex.

So I changed to 18500km. Then shows the odometer 99999.

I am sure that I am working against the correct version M73 V1.
What is the error that makes it became 99999?

I tried to change 18500 to miles and made it again but there was no difference.

What shall I do now?

Thanks for your replies.

Crc thats why shows 99999,it was model 2000 thats why tacho couldnt calculate it,the only way is program it back with original dump,
u are lucky enough that the car starts cause there is a immo in cluster

The first file I upload was wrong , I've attached a proper.
I can see my pin code in hex.
"0340:FF 00 78 FF FF FF FF 00 FF 00 0A 03 04 A6 41 55 ..x..........¦AU"

But can not figure out which line is the odometer.
Can you help me with advice and tips.

This text file is not good to edit. You need to save a binary file instead.

Anyway the mileage are those 2 big blocks:


If it has checksum, it's usually near the bottom.


We can try to help you but you need a good read file.

If your A3 are between 2003-2005 year, then use VDC- Vag Dash Can v5.29 very powerfull tool for A3, and A4 (2001-2005).
In some cases work A3 2002/2001 year...
