Flood damaged 996

[simonk996]

Hi!

I'm a new 996 owner based in Warwickshire 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. The purchase price fortunately lends itself to either.

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 (the passenger door isn't 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

Simon! Brave man! The alarm control unit will likely be beyond salvation, but it is worth giving it a chance. Take the lid off and dry it thoroughly, and brush any corrosion and rubbish off the circuit board. Put it in the airing cupboard for a couple of days. If you have to replace it, you'll need the Porsche security codes for the car, and get someone with a Porsche tester to program it. A second-hand one won't work, unless you know the security codes from the donor car. Hopefully the water level won't have reached the DME, or the relay panels, front and rear. There are connectors in the rear footwell which will need checking, but you have no doubt found them while the carpet is out. And it would be worth checking the connectors in the door shuts. If it has door speakers, they will be toast, but no big deal to replace. Lets have a few photos (the good, bad and ugly), and I hope you'll keep the thread updated as you progress. It sounds like an interesting project, and I'm sure I speak for everyone when I say that it will be a good story to follow.

Wow! Brave or Crazy!!! Good luck Simon!!!! Love to see photos and please update us with progress.

What they say ^ - some photos would be great. I'm not sure what you mean by the seat squab - how high up is that? If you find a decent workshop manual, let me know?!

..... er ..... seat high! The bit you sit on!

good luck with the project Simon, would be really interested to see work in progress photos

Can I ask what she cost?.

 

[Richard_Hamilton]

I'd say she is priceless if she helped him strip out the interior..........

Thanks for the warm welcome everyone! I'll definitely try and keep this thread updated with progress and as suggested, to kick things off, I've added some pictures - the good (the exterior of the car is pretty much immaculate) and the bad/ugly (the rest!) 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. It owes me £3k so far and as I said, I'm not sure what the ultimate plan is, but if I can get the seats looking good, I will. 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?

Lol!!!! Blimey how did the mould get to the steering wheel and almost the top of the seat?

The immobiliser is incorporated in the alarm control unit. Both alarm unit and DME are programmed with the immobiliser code, and this has to match before the engine will start. The immo code can be changed in the DME if the (IPAS) security codes are known, but the alarm unit can only be programmed with an immo code once. Therefore, if you buy second hand, you need matching units, and keys which have been programmed to this pair. However, if you don't know the IPAS codes for them, you will never be able to code new keys to them. The alarm units aren't too expensive (about £150 iirc), so if the DME is OK it would be much better to get a new alarm module, and have it programmed to the car. Assuming you have the V5C, an independent (or Porsche dealer) will be able to get the IPAS codes for the car. As for the leather, I have had excellent results with Dynamix dyes. It would be worth buying a small kit, and see what results you get. This all has the makings of a great thread - keep it up!

 

[Richard_Hamilton]

Oh yes, and if you do need a DME and decide to get second hand, it would have to be the correct version for your car. Again, if the IPAS codes were known, then the fuel map and other settings could be changed.

Simon, #12 on your post at Rennlist could be useful. Regards.

Hi, if Simon isn't interested in the savannah interior you have removed, could I have first dibs on one of your panels. It's the rear interior panel which fits across the car under the rear screen. Will yours fit my 99 c2? Thanks

 

[drmeng]

Sorry haven't got that part but looking for one in black swap ? Have front and back door cards full carpet front and rear seats all I savannah and speakers

There is a company in Parkstone, Bournemouth who can repair ECU's etc, they repaired my Tiptronic ECU in my Audi when water from the scuttle flooded the ventilation system ( quite common on the A4 range - but don't tell Audi Let me know if you want their details.[]

As you've already stripped out the interior why not build it as a race car? I see they've started letting 996 into club racing as of this year. I think you'd have a finished project sooner that way, and if you don't race your self maybe you can sell it with a profit. [] Good luck anyway, seems you're weekends are booked for some time.

Looking at the amount of mould inside the car, top marks to the wife for helping you strip it! Good luck with the restoration. What about a GT3 RS type interior?

 

[simonk996]

Hi guys, Just to let you know that the resto has stalled a bit due to work (helps to pay for things at least!) Should be back in action this weekend, so I'll give a full report.
