Hi everyone,
I have a VW with the Immobilizer 2 module, and after disconnecting the battery to perform some engine work, upon reconnect the car cranks but does not fire. Investigating with a VAG-Com tool showed the ECU reporting P1570 - Engine Start Blocked by Immobilizer.
Reading appropriate data blocks from the Immobilizer module showed it still recognizes the key, can communicate with the ECU, and does not appear to be disabling the motor (also no Immobilizer-specific trouble codes).
I don't believe I touched any wiring between the ECU and Immobilizer, but I did have the batt disconnected for a few days. Any suggestions as to where I should start would be greatly appreciated!
