Starting up a 987 boxster after water pooled behind LH seat
Discussion
The windows where left down on a 987 boxster 2.7L, 180 kW (245 PS; 241 hp) over night during a rain storm... (i know, dont ask)
This is a UK spec right hand drive car so drivers / passenger side in the below may be swapped if your familar with the left hand drive version.
In the morning there was water on the drivers side (right hand side) window, seat and boot controls, but not too wet behind the seat.
On the passenger side there was water on the window and seat controls and about 1/2" to 3/4" of water pooled behind the drivers seat. The battery coincidentally also flat so i havnt tried turning the car on yet.
Ive begun to mop out the water, so far with lots of towel which got the majority of the water, and i now plan to rent a dehumidifier to dry out the car interior further, but is there any danger the electrics / systems or anything else i should be aware of when i try to turn the car back on ?

Under the left hand seat on the floor is a thing called the immobilizer. It is basically a circuit board that interfaces with the locks, ignition switch, etc.
Getting water that deep may mean anything from corroded contacts to circuit board damage.
The usual process is remove the seat, remove the circuit board, wash the circuit board and contacts and use electronics cleaner (a spray can).
Run a fan for a few days to totally dry out the carpet area lest you get mold. Reinstall and test.
There are people who can rebuild the immobilizer if they get the old one with all keys. You can't just buy the immobilizer as it is linked/programmed to the keys.

Thanks EDC
How would i remove the carpet ?
I can see there is a panel that looks removable low down behind the site, but its a upright panel. The floor panel and the higher up panel (that is not so wet) seem glued in
The rear panel behind the seats is to access the engine. I don't have a 987 so don't know where all the fixings are but they shouldn't be too hard to find. IIRC you will have to remove the seats. Watch out for any seatbelt pretensioner or airbag connectors. Also have a look on boxa.netHow would i remove the carpet ?

I also suspect that it may not be the case that you left the windows down. You may well have water ingress from blocked rear drains and/or leaky door membrane. This will cause the carpet to soak up water and make your alarm module wet and this might cause the window drop.
If this is the case then you need to sort the cause and not the symptom of merely a wet carpet.
