Scuttle/Drain clearing

Post by Foxmeister » Fri Oct 16, 2020 3:55 pm

So following on from my stereo issue im having, this apparently stems from moisture found under the carpet that oxidises the main cable connection

So im looking to find out what areas need clearing out for drains or similar, ive already removed wipers and plastic scuttle to find some odd leaves etc, but cant see any blockages or anything, is there any other known areas i should look for these?

I once found a small puddle in the spare wheel well when i was charging the battery, no idea where that came from

Check that the AC drain isn't blocked. Check around the rear light clusters.

If there is water soaking the carpets then evaporation and condensation could mean some water in the spare wheel well. How much was there?

If you've got a sunroof, check the drain from that is clear.

Nice one Shopp

Was about a fingertip of water at best, dried out with some kitchen towel and not returned,

There is to me, a kinda fusty smell, so assume there has been moisture in there for a bit

Where is the AC drain exactly?

No sunroof, and i'll check the rear light seals also

Sounds like it could have been condensate then.

AC drains through the floor near the transmission tunnel under the dash. You can see the rubber hose coming out from under the car.

Check the pollen filter seal/grommet, too. Doesn't have to fill up for in the scuttle area for water to leak in there.

The rubber bung under the coolant reservoir was full of sludge and sealed up on mine. As soon as I poked it πŸ˜‹ it dropped out the bottom and then all the built up liquid πŸ’¦ ran away

If anyone has a collection of pictures of all the places to check then I think they would be really useful in the FAQ post. πŸ‘

Ooh matron...

Do you mean the bung fell out? Did you replace it or leave it out?

Left it out mate. It’s there to protect the edge of the metal. I’ve sprayed some wax oil there as a better measure. If it’s not done before then I will get some pics over the next week or so when I’m on restdays
