I have a 2002 audi a4 TDi, I lost the key for it and audi told me i needed new dash, ecu and key set, so i removed the ecu and sent it away to have the Immobilser removed, it was removed and runs fine now, but once started after five seconds the hazards start going off also the Aircon unit doesnt work, faults in the Central Electrics ECU Immobilser fault, and in Aircon ECU Immobiliser fault, i think i need the immobilser taking out of the dash!
