Hey Everyone,
My girlfriend's car (not her primary transportation) has been having issues with the immobilizer for the past few months. In fact this issue is why I bought a VCDS cable in the first place.
It all started after we moved, her car has been fine as far as the immobilizer was concerned, never had any issues. At the new place it had sat for a few weeks and when I went to start it the battery was dead, no big deal I've had batteries die before (especially in my project car), so I pulled the battery out, booked up the Battery Tender and let it get fully charged. After the battery was charged and reinstalled when I tried to start it I got "Immobilizer Active" on the instrument cluster and the flashing car-key symbol on the dash.
Since getting the initial issue, I've been able to get the car started and driving on occasion. The first time I was able to get past the immobilizer I left the key in the ignition in the "on" position for 3 or so hours with the car hooked up to the Battery Tender. After I went back out I was able to start it and the error on the cluster went away. However the issue came back after cycling the key.
I disassembled the steering wheel column enough to disconnect the plug going into the D2 Reading Coil and to wiggle that around to see if the wires had any corrosion or issue, there were none I could find. I've also removed the instrument cluster and made sure the cable going from it's connection to the D2 Reading Coil wasn't pinched or frayed.
Another thing I tried was to take key apart (sadly there's only one key for this car, so no idea if this key is dying), and then try and start the car with the physical key for the car, but with my Jetta's key right next to the reading coil. The only change from doing that was an additional fault in the immobilizer in VCDS
I have swapped batteries, and taken the battery for the car in for a scan at Advance Auto Parts, it passed.
The weird part to me is how it is intermittent, most of the time I get the error, but occasionally the error will go away and I can start and drive the car. When that's happened the immobilizer and engine have zero faults in them and the battery voltage is around 14.2 V. When the fault is there, the scans are done with the car off and voltage is around 12.5 V. I do have hooked up to the Battery Tender currently. Below is the latest scan from the car, which the car hasn't driven since I put the original battery back in, so some errors exist in the scan that will go away when the car is driven.
