Water mystery in footwell

That should be easy to plug with a rubber well nut of a suitable size.

That's it! Exactly the same location. I will post a pic before I plug it. I never new Botang's hole was there, I thought it was further down closer to the middle.
What a nightmare!
The location is pure genius, it is positioned to trickle water down several wiring looms, drip onto relays and onto a group of earthing points on the chassis!

Thanks I will give those bolts a try. I was going to just use an aluminium bolt and washer filled with silicone, but those look better.

Thanks for your help

P.S. even though it rained all night, this morning no more water in the footwell, so hopefully Botang's hole is the only leakage point on mine.

I used a couple of those well nuts to fix my reversing camera, they work really well. Make sure you get brass (or stainless steel).
Easy to fit, access for fixing needed from one side only, good seal, simple to remove/replace, no problems with corrosion from metal contact.
(And if actually used to fix something are surprisingly strong)

Finally fixed it. I couldn't get any of those well nuts in time so I used a M6 aluminium bolt and one of those Audi anodized nuts filled in with silicone rtv sealant and a nylon washer and tightened. It was a right pain to fit the nut and tighten from the inside but surprisingly can be done by one person.
Then filled the whole area where the original fabric patch was with more silicone.



Sorry this pic is upside down

Glad you sorted it Goran

After lots of heavy rain I've been seeing a wet carpet in the passenger footwell and also a trickle of water running down the carpet over the wheel arch. I'm pretty sure it's Botang's hole. I like the idea of a rubber well nut for simplicity, does anyone know if an M6 would be big enough?

[Goran]

I forgot to measure the size of the hole. Its definitely bigger than 6mm diameter, I put in an Aluminium M6 bolt and M6 nut and there was still room, its probably M8 size.

Thanks Goran. As they're quite cheap I'll probably buy a few different sizes and see. If the hole is about 10mm diameter I may need to go down to an M4 due to the thickness of the rubber on the nut.

[Goran]

I can confirm my water ingress was almost definitely that hole, the car has been through at least 7 days of heavy rain now and the carpet is nice and dry.

I just did this on the FE I have in at the moment and I used one of the big plastic rivets which are used on the arch liners, well covered in seam sealer.
