OK so here is some further info on my water ingress issue. As predicted the wires and cable blocks were in a very sorry state, so I have elected to replace the wires (corroded away or really mucky). It looks like the pins that nestle inside the block will be nigh on impossible to remove and reuse so of to Skoda to get new stuff. Skoda dealer was reluctant to order the wires because his minimum quantity is 5 pieces but he did suggest I go direct to their supplier TPS. So here are the part TPS numbers for anyone else in the same predicament:- 1J0962615 Housing (cable block). £3.03 S1J0962623 Housing (cable block). £3.67 000979131E Wire Set. £3.66 S000979253E. Wire Set. £10.64 000979225E. Wire Set. £4.99 S000979021E Wire Set £4.99 All above prices are for one wire you must add VAT to them The wires can be bought individually and one wire has a connector at each end, so to do two wires of the same diameter with the same ends you just need one of the wire set. All the wires are yellow so you need to be very careful to match up to the cable block to the loom. They also sell inline wire joining connectors but I bought two 50 packs of the two sizes I need from 12Voltplanet.co.uk, far cheaper and I need some for when I rewire my motorbike this winter. The ECU is about £300 so I'm hoping that a good drying out and plenty of contact cleaner will give me some functionality back. Carpets are just about dry now so I shall be onto this on Thursday (22nd). Hope this helps someone else. Cheers Ade

Delboy, the wife and I are up in Scotland for 22 days at he end of the month. Taking the CalMac Island hopper to do the Hebrides in my MX5. They tell me that in September the Hebrides are like Barbados, it is certainly costing just as much. Looking forward to open roads, fantastic scenery and some awesome seafood rounded off with good company and a few wee drams. All thoughts of the Skoda will be long forgotten. Bring it on.

Thanks for the very fast reply Techie I'll be round to my dealer in the morning, what's the betting that they are only available on back order. Still I reckon I have at least 3 days before the carpets are anywhere near dry. Thanks again you guys are great. Cheers Ade

First dry day so set about the water soaked carpets. Before anyone follows my lead I must emphasise that you must disconnect the battery and wait at least 10 minutes before you disconnect the yellow plug under the seat. This is the air bag live feed. The other two, a black one and a green one, simply unplug. Never had the electric passenger seat out so it took some time to figure it out but eventually I managed to do it, and aren't they heavy? Then unclipped the door aperture trim and lifted the carpet. Wow!!! There must have been over 1 gallon (4.54 litre) of puddled water, carpet and felt backing absolutely dripping wet. The ECU box was full of water too, and I do mean full. It has been like this for some considerable time, amazingly no rust anywhere on the floor pan! Took out the ECU and stripped it to the circuit board and dried everything off. The plugs and connectors are very well corroded and fact some are rotted through. I need new inserts for the cable ends that go into the plugs (anyone know where to get them?), I managed to clean up the pins with emery cloth and a lolly pop stick. The carpet is now wedged up and I have a dehumidifier set at 30% humidity in the car. I have used about 30 broadsheet newspapers to soak up the thick of the water, still a long way to go though. I reassembled and then reconnected the ECU, no smoke or smell when the battery was reconnected, which was nice, so I tried a failed circuit. Result, the powered driver's seat works! Left it at that for now, car starts and runs so that's good too. It would be nice to get the connector blocks up to scratch but as noted above I need new ends for the cables. That whole lot took me about 2 hours at least 1/2 hour of which was struggling to work out how the seat came out. Whilst the Skoda is laid up to dry out I am using my MX5 Mk1 which is my real pride and joy so there is a kind of silver lining. Thanks once again to all that responded, I hope the above helps someone else. Cheers Ade

Update to my issue After the rain had stopped I set about resolving the immediate issue which was the siren. Removed the plastic covers over the rear of the engine bay and after removing the wiper arms I also took off the lower windshield trim. Unfixed the battery terminals, fully expecting a siren but it was silent. From the information provided in a PM I then did further work to completely remove siren, so that issue is a permanent fix. I turned my attention to the issue of water ingress so I then removed the battery. Removed the two 12mm nuts and bolt to get the battery base plate locator off. Underneath the base plate I found a rubber grommet, but it wasn't blocked! In fact it was not a whole grommet, it was basically an open plug and there was no water to be felt. The year before last I had the pollen filter replaced and the AC re-gassed. Now I notice that the pollen filter is open, I mean that the cartridge is not covered but looks like it ought to be covered. I'm thinking that the AC 'specialist' didn't bother to replace the cover and the enthusiastic use of a pressure washer by the hand wash monkeys my wife uses was probably filling up the car via the pollen filter. Apparently that is my fault, I should have told her that jet wash was not a good thing (I am sure I must have but quiet life, accept it). I've sent off wife of to collect a lot of newspapers to soak up the thick of it then later this week I will be taking out the passenger seat, lifting the carpets and putting a dehumidifier to good use. I will look at a rectify the wire and connection damage and also see if a spell in the airing cupboard will restore the ECU. At least the car is now usable again and my neighbours and I can get some sleep. Thanks to everyone for their helpful advice and instructions, I really could not have done this without you. Cheers Ade

Thanks to you both, and thanks for pointing out that my 2.5 TDI is a series 1 (I thought it might have been S2 as it was registered in 2007). So now I can clearly see the culprit and know what to do. Tomorrow is solution day, then I will put a dehumidifier in the cabin for a good few days. Is the water affected ECU expensive? Silly question I suppose. Thanks again Ade

How do I convince you that I'm not a scammer? If you can't tell me then how did you find out? Is there a workshop manual that I can view on line? I need to get a nights sleep and so do my neighbours. Mine is a 2.5 V6 diesel so I think the engine bay layout may be different to the four pot models. I looked under the cover of the scuttle on the passenger side but can't see a thing. When it goes off it sounds like it is somewhere near the box that houses the brain thing (by the way I took that out and cleaned up the terminals and then cruise control started to work again). I've tried pressing the button in on the B post by the drivers seat but that doesn't stop it. The remote unlock stops it, but then it starts again. Got to go because it has set off again.

Loved owning my Superb and expected it to last longer. The 2.5 V6 diesel pulls like a train, I had it chipped and economy improved (if careful with the right foot) and performance went up massively. Comfort and space is still impressing passengers and the body has no signs of rust. 102,000 miles, full service history and timing belts etc., done, it is set for a good few years. Rainwater has leaked into the car, carpets sodden through and electrics going haywire. Windows sporadic, key fob will not lock/unlock, boot cannot release (open with key) alarm sets off at any time (even when driving) and carries on. My garage can't do anything until Tuesday in the meantime it is waking up the neighbours, attracting attention driving and driving me round the bend. leaving the car unlocked/locked makes no difference. The garage says this is a notorious fault caused by drain holes becoming blocked and whilst they can sort that out the carpets will take eons the dry out. I don't care if the alarm never works again I just need it to stop! I am tearing my last remained hairs out. Can anyone tell me how I can disable the alarm. Cheers Ade
