How to use Digiprog 3 Xprog do eeprom reading in Audi A4 cluster

One technician share testing guide on reading eeprom for Audi a4 2001, in order to copy the immo information from a cluster to another, and make the mileage follow with the immo information. If clone all eeprom content than the mileage is transferred too.

 

What tools can be used to work with Digiprog3 ?

Ecu programmers like Xprog, Carprog, UPA USB programmer

Original cluster:

The Jaeger cluster barely works

 

Note:

read the pin code from both the Instrument and adapt it to the vehicle

What to do on pin 21 and 22 on the chip?

– With car ECU programmers:

Eprom.set type,mcu,hc12,read,save.
eprom,set type,mcu,hc12,file,load,write.
Buy yourself Xprog-M programmer, Carprog full, UPA USB.
Pin 21 and 22 jumper after programming or wait 10 minutes.

– with Digiprog 3:

digiprog3-read-audi-mileage

Eprom,set type,mcu,hc12,read,save.
eprom,set type,mcu,hc12,file,load,write.

Reference:

Eeprom HC12 read and write to the other counter:

AUDI MM AB 8/2001 DIAGNOSIS / TACHO DIAGNOSIS

(Write down the exact ALWAYS old / incorrect Mileage)

The diagnostic port is in the driver’s footwell. Turn the ignition on a vehicle. Connect plug ST16 the diagnostic port and the DIGIPROG.

Select the program: cars / trucks – AUDI – MM 4 / 99- DIAG.

The DIGI PROG II shows you the old / incorrect Mileage.

Enter the new / correct Mileage and confirm this.

Should be then after programming on the speedometer 999999 KM give

The old / wrong KM value again so that the speedometer again the old / false indicates KM. Now you build the speedometer and break it to the see board. Solder the green and black wire to the same color marked

Arrows at. Now connect the blue and the green plug with the speedometer and plug ST41 with the DIGI PROG (picture on the following page.)

Now select the program: cars / trucks – AUDI – MM 4/99 HC12.

The DIGI PROG shows you the old / incorrect Mileage. Enter the new / correct Mileage and confirm this with the hook.

Now shows you the DigiProg II 5 min wait. Remove the connection between the DigiProg and the speedometer, wait 5 minutes and build the speedometer again. Alternatively, for 5 min. Wait, you can also like in the image on the next page shows the pins 21 and 22 bridges.

Here necessarily the board from any power supply (Digiprog3 v4.94, external power supply, etc.), Pin 21 + 22 bridge, and then you can use the tachometer.

Immediately reinstall.
