Thanks friend i have used a passage 1.8t ecu in a S3. .... I've flashed eeprom and flash but epc light is on and control module fault..... but if I flash originae back up ecu is fine..... I know logic is stored in mpc so maybe there's a slight difference causing the epc light to remain on but car drives fine
