Immobilizer Delete / IMMO OFF EEPROM Programming Service ? For Volkswagen VW AUDI ECUs (PN 7.1, 7.1.1, or 7.5 ONLY) ? Description: This listing is only for the immobilizer delete (IMMO OFF) EEPROM programming service for your ECU that you mail to us! ? What is an Immobilizer System? The immobilizer is built into the instrument cluster, working by reading a secret code from your key via an antenna around the ignition. If accepted: The immobilizer allows the ECU to enable engine functions (fuel/spark control). If not accepted: The immobilizer lamp flashes, and the ECU prevents the engine from running. With this service, we reprogram the ECU to permanently enable engine run functions without needing the immobilizer?s approval. ? How to Know If Your Immobilizer is the Issue: ? Immobilizer lamp flashes when the key is turned to the "ON" position. ? Fault codes: P1570 or 17978 appear in the ECU. ? "Engine start blocked by immobilizer" shows in live data or DTC descriptions. ?? Important Notes Warnings: This service won?t resolve non-immobilizer-related no-start issues. The immobilizer lamp in the dash will still flash (it?s not controlled by the ECU). If the car doesn?t crank at all, it?s NOT an immobilizer problem. If the car runs briefly (1?2 minutes) then stalls, this isn?t an immobilizer issue. If the engine runs rough or misses and stalls, the problem is elsewhere. If the immobilizer lamp cuts out but the engine won?t run, you likely have other issues. ? Key Immobilizer Functions in these ECUs: Immobilizer checks for a matching key only when the key is first turned ON. If the key is accepted: The engine will start. If the key is not accepted: The engine will crank but won?t run for more than a second. ? What This Service Includes: ? Immobilizer Delete / IMMO OFF programming in your ECU. ?
