Flood damaged 996

Hi! I’m a new 996 owner based in Warwickshire over in the UK. And last week I bought a flood damaged 2001 Carrera as a bit of a (very!) long term project. I’m under no illusion that it’s going to be an easy fix, but I’m quite looking forward to stripping it down and getting it running again! Long term, I’m planning on keeping it either as a road car or track toy, depending on how the restoration goes. I came across this forum after trying to locate the bonnet and engine emergency releases, so I thought you were the right people to give me a few pointers! The car was parked (engine off) and fresh water flooded up to a level just above the seat squab and there is a bit of silt knocking around. Unfortunately, it was sitting for a month or so before I go it, so the interior was quite mouldy. Over the weekend my very willing wife and I stripped the interior out and gave everything a thorough clean. The seats, carpet, sound deadening are currently drying. All the mould has now been removed, but there is a bit of staining on the back of the seats. Since getting the car it has either had the driver’s door open in the sunshine (can’t yet get the passenger door unlocked yet) or a dehumidifier running; which seems to be doing a good job of drying things out. I’ve had a look at some other flood damaged posts and I’m pretty confident that I need a new immobiliser/ecu/key set to get the engine going. Obviously, prior to any of that, the plugs are coming out/oil changed etc. My first question is whether there any obvious water traps that I should be aware of? I’ve had a good poke around with an endoscope in any interior access points I can find and things are looking good, but others may be able to point out something I’m missing. Are there any other big things I should be looking for? I’m guessing electrical problems are going to be my biggest headache, so any advice would be greatly received! Cheers, Simon

Wow, don't envy you in the least with the exception of having a willing wife by your side. Under the seats is probably the main trouble area & you will want to replace everything located there. I have seen a few new OEM wiring harnesses on E-Bay you should have a look at. Good luck!

Figure out how high that is relative to engine, exhaust, cv axles and be sure to inspect them for intrusion. Did it get high enough to touch the bottom of the gear shifter? If so the airbag module sits on the center hump. You also have your fuse panel on the drivers kick plate. I PM'd you -- if you need something -- let me know. I'm parting out a pair of Boxsters and they share a lot of common parts. Mike

Thanks guys! It's currently got a fan heater and a dehumidifier going 24/7 which seems to have made a big difference to things. The mould is now all gone, but some staining remains. My biggest question at this stage is regarding the electrics (surprise, surprise!) I think the immobiliser is pretty much shot. Unfortunately, a couple of resistors (about 1.5mm long) on the PCB have come lose. I've got one of them, but the other is nowhere to be found. By the looks of it, the fuse on the immobiliser board blew, so I was quite hopeful about it maybe functioning again, until closer examination revealed the resistor issue. It and the DME have been thoroughly dried and cleaned and I'm planning on finishing off cleaning and checking the electrics this weekend and attaching a battery, just to see where I am. Am I right in thinking that if I get hold of a matched DME, immobiliser and key head, I might be in business? Will I still need to get things coded if it is a full set? I'll keep this thread updated with progress.

How did you do with this project? I have an 2001 996 Carrera that also had water damage. Were you successful getting it running? What all did you have to replace and repair? Thanks
