Need help! Water in the driver's floor

[Tweetdriver63]

I will go ahead and answer some of my own questions, since I've found out more since I posted this.

First of all, the source of the water was a clogged drain. Seems this is a pretty common issue. Unfortunately, I didn't know about it until it was too late. I've cleared that up now, but still have the problem of what is apparently a fried immobilizer control module.

I'm looking into the possibilities. One is ECU Doctors, which runs about $800. The other is to buy a new module (Jim Ellis Porsche in Atlanta has it for $442 on their online shop) and then take it to the dealer to get everything reprogrammed. I don't know the cost there yet, but it seems there can be a lot of variation, dependent on the dealer.

Am I right that buying a used one on ebay, or elsewhere, isn't really worth the risk?
