Reading eeprom MM Audi A3 8L 2002 cluster, what hardware?

Car model: Audi A3 8L 2002 8L0920932M Magneti Marelli cluster

 

Purpose: to read and write the eeprom of the mcu chip

 

2 Motorola chips:
Big one:
MC912DG128ACPV
3K91D
HHVD0217
504000001309
V8.51 DG128AH
FP2203461
02/170

Small one:
MC908AZ60ACFU
3K85K
HHWD0216
504000001109 HG
V8.51
FP2203570
02/175

 

Attached photos to see the chips for yourself.

Which one contains the eeprom data with mileage, pin etc? What hardware can read and write these chips?

 

  1. Read eeprom 912DG128 – Xprog, UPA

 

  1. DSP3+ will do it also, carprog, x-tool as well.

I have been mainly using Xprog V5.55. This is the best source of Xprog:

And testing images below:

Connect the adapter to Xprog;

select chip (i.e Microchip 24xx128)

Click on “Read”, it will show the VIN number.

What about Carprog, does it read the data as the same as that of Xprog?

We select chip.
