Modification instructions for Audi A4 B6/B7 and Seat Exeo instrument cluster display

Before installing the new SEPDISP13 display, please read carefully the following instructions. Our technicians, for illustrative purposes only, have made a video tutorial about how to repair the module.

Warning: this process is recommended only to expert and qualified staff

  • Replace the display in an ambient temperature of 25 °C.
  • After replacing the LCD, switch on the cluster (pin no. 2 and pin no. 3 positive, pin no. 18 negative).
  • Identify the PCB of your dashboard (PCB1 or PCB2) and measure the voltage between the points A and B with a multimeter

  • If the voltage measured is between 7.0V and 7.2V, no modification is necessary;
  • If the voltage detected is instead lower than 7.0V or higher than 7.2V, it is necessary to do the modification described in the following paragraph “EEPROM MODIFICATION“.

NOTE: For this modification, it is necessary to use an EEPROM programmer.
We recommend our SEP-EECLIP.

First, set the programmer reading in hexadecimal (HEX).
• De-solder the 24C08 EEPROM, highlighted in picture 3.

ATTENTION: Make a backup of the EEPROM, before the modification.

To reach a voltage between 7.0V and 7.2V, it is necessary to modify the value of 039B location;
Please note that increasing or decreasing these locations by 1 HEX unit, the variation will be +/- 0.09V.

If not familiar with hexadecimal calculation, it is possible to use the calculation tool in the box beside, simply typing in the values.

NOTE: The tool works correctly only on computers. For the mobile version, click here.

Once these modifications have been done, measure again the voltage between A and B points and check that it actually is between 7.0V and 7.2V. If not, increase or decrease the location until the value is as close as possible to the right range.
