Hello,
I have a MK4 Golf GTi from around 2001 - Unfortunately the instrument cluster has failed. I don't have any of the VW diagnostics tools but do have a USB-UPA programmer which I have tried to read the dash EEPROM with (desoldered the EEPROM etc...). Unfortunately my dash EEPROM seems to be unreadable so I cannot retrieve the codes!!
I have tested the UPA-USB with another EEPROM (A 93C56 from a Suzuki GSR600 dash - this reads ok). However the VW 93C86 will not read at all. I found the DO pin was corroded and have managed to carefully file away at the IC's package and attach a wire to the copper pad within the IC but still no luck reading.
Am I able to read the secret codes etc. from the 20XXX EEPROM inside the ECU? If so what information will I need to program my new Immo 2 dash?
I originally just intended to backup my original dash EEPROM and flash the dump to the new dash however this option is now out of the equation!
Many Thanks
