What About the Immobilizer? Volkswagen’s immobilizer system (IMMO) is used to authenticate or reject the key. The IMMO is not a part of the vehicle alarm system, and it won’t prevent the engine from cranking over – at least not initially. If the IMMO doesn’t authenticate the key, it will shut the engine off within 1-2 seconds.
To do this, turn on the ignition, use your centralized button to enter the digits, several quick presses (example: 2 for digit 2) then a stop of one and a half seconds to validate the digit and resume, duplicate the operation until you have entered the entire code. This should enable you to start your Volkswagen Polo without having to remove
If you had a used Immo 2 RFID chip you could recycle it and program it onto another car with an Immobilizer 2 system. VW cars made from 2002 - 2005 have an Immobilizer 3 system built into the dash and the ECU. Immo 3 RFID chips are read/write devices but they can only be written one time. When this is programmed, the sensor RFID sensor ring on Re: Possible to disable immobilizer. The immob fault is probably a one off. If the starting problem is the immobiliser, the engine will start for 1 or 2 seconds and then stop. Your problem could be air in the fuel lines, coolant temp sensor, starter, battery voltage & earth, timing, temp sensor or glow plug fault. The immobilizer is a theft deterrent system located in the instrument cluster, the main car computer, a radio frequency identification (RFID) transponder chip in the VW or Audi smart key, and an antenna at the ignition cylinder. You cannot do an immobilizer bypass with normal "car theft" tools so don't bother asking. psjxMD.
