I have picked up a 2004 a4 1.8t and from the symptoms I believe the ecu has suffered water ingress. I have a replacement and i need to get the pin or skc from the current ecu/cluster and from the donor ecu to be able to swap them over with vcds. I have tried various cables and vag eeprom programmer etc but not sure if the "no ecu found" is my laptop/cable/software or the car. So would appreciate help from someone that has a known working cable and app.. That CAN read ecu and cluster pin codes
