Thanks for the quick reply. I came back here just to post that I just checked under the driver's seat (I previously thought that the immobilizer was somewhere else) and it IS quite wet down there. Even after driving around for an hour or two with the top down the carpet is soaking wet down there. So fried immobilizer? How much do these things go for? Do they need to be reprogrammed?
The one time I leave my hardtop off...
