Last night, I put the key into the ignition and it turned 360 degrees with no resistance. I pushed the key in toward the steering column, and the switch worked normally.
This morning, I could not get it to fail. Push in, pull out, wiggle the key, the switch worked normally. I was about to disassemble the switch to examine it, when it occurred to me that, if something has failed, disassembling it may cause it to fall apart, leaving me with an undrivable car.
So, I thought I would ask if anyone has seen this failure mode before, so I can order the right part before taking the thing apart. Does anyone know, is this a failure of the switch or the lock cylinder?
Also, when replacing the lock cylinders, VADIS talks about software being required. Is this because the key and the immobilizer need to be paired and stored in the computer? Does replacing the switch and not the lock cylinder not require the software (and the expensive visit to the dealer)?
