Well my RS quietly slipped into a coma over night....not even central locking will work....I have a vague recollection of some kind failure due to a puddle of water in passenger foot well, can anyone point me in the right direction please.....?

Ok i found where the water was coming from....yes a blocked drain hold under the coolant expansion bottle, several litres drained out once un blocked....so now i guess i have to wait for the foot well to dry out and im guessing replace whatever is down there under the carpet ?

Get the TCU and convenience module out and get as much water out as possible asafp. Then liberally spray their circuit boards with WD40 to displace the water. Then spray with contact cleaner to get rid of the WD40 and then cross your fingers.

Do the same to the electrical plugs for them.

Remove the carpet and dry thoroughly.

ah man cheers for for that sounds like i might have underestimated the problem....I'm on it !

also find any loom wiring joints under the carpet and give them the same treatment as Shop said with the wd40 and them contact cleaner

Yep. Probably a good idea to re-solder the joins in the loom (with the rubber bullets on) mine looked fine but caused me all sorts of problems until I stripped them back and soldered the joints again. Seriously, even if they do look fine. Just do them again!

Great thanks everyone, its very much appreciated I can t move the passenger seat due to electrics being dead so im going to get it to the garage in the morning.....Just a quick question, the rear footwell drivers side it was full of water too, any wiring to watch under the now seriously damp carpet ? .....thanks again every one

Don't think so.

Nver tried it with an ECU but drowned iPhones can be saved with rice - it absorbs moisture and qucikens the drying out process...

Presumably silica gel is even more effective then.

Hi Guys, everything is dry but i got zero power.....is there a big arse fuse anywhere that i can check ? the bulkhead next to pollen filer was full of water so if something was in that area its been under water
cheer

Yeah, there's a big 200A fuse under there. Might have corroded away to nothing. You'll have to get the expansion tank out of the way to see it.

Found it....your right corroded to nothing cable is hanging loose....fuses look ok but no power getting to them... Thanks again and unit 20 for the advice...very much appreciated
