I have a 01 Boxster that won't start. I am almost 100% sure that it's the immobiliser but I'm not sure of the next steps.
The alarm went off, I unplugged the battery to stop it, reconnected it and everything works BUT it won't start. The carpet is soaked so I removed the seat to find a good amount of water underneath. I removed the immobiliser to have dried the box and circuit board. I do see some corrosion and there was some condensation and water inside. I'm not sure if it will still work or not. I plan to let it completely dry and then reinstall to test (btw do I have to reconnect the seat wiring of just the immobiliser unit to test?).
Has anyone had this issue and successfully repaired it? Do I need to go online and buy another circuit board if this doesn't work??? and if I do should I get another key, transponder, ignition, etc to go with it??? Does it have to be reprogrammed by a dealer???
Any advice would be greatly appreciated.
