My 2001 Boxster S got caught in a New Orleans flash flood and corroded my immobilizer and now the car won't start and does a faint ticking.
Because it was under the drivers seat and super easy to remove, I took it out and put it in a Crest Ultrasonic cleaner. Alas, it didn't save it.
So I went on eBay and
found this complete with keys: But someone told me that
"only the dealership can replace ECU/immobilizer"
