As the title suggests, due to breakage of the old engine control unit (not readable), I have to replace the ECU with a used one with the same codes in the ECU and software. The ECU in question, and' a ME 7.5, car audi TT 1.8 t 225cv four of 1999.
Wonder if someone has already experienced a similar case and if it is necessary to resort to the dealer for the exact coding of the control unit to the fni of the funzioanemento with all devices (butterfly, electronic throttle control, etc.) (immobilizer), or you can do the swap without too many problems without having to ask in an audi.
From someone I heard that for the audi, and I need to go to audi as they connect to the server of the mother house and download the configuration.
According to others, this procedure is not necessary on the car in question (1999) and argue that once you have put the immobilizer should work correctly (ECU with the same ID software/ecu).
Thank you and I wish you a good 2014 to you all.
