Title: Water build up on rear sills
Post by: greencode on 15 January 2023, 14:25: I have an issue whereby water is building up on the rear door sills of my 2017 R. The offside is much worse than the driver side. I’m presuming it’s the common problem of the speaker seal but just wanted to check before attempting to resolve the issue.

Any thoughts?

Lots of head scratching an garden hose came to conclusion was comin in around white pops that attach door card to door. Sealed that up also an 3months later all dry. 🤞🏻🤞🏻

You'll be fine it's not difficult, I'm sure there's a vw repair guide somewhere that tells you the correct size of drill bit to use, then just follow it up with some anti-rust paint. I'd use rivet nuts when redoing the speakers, as if it happens again you can just unscrew the speakers, so less damaging.

Post by: ub7rm on 20 January 2023, 11:01: It will almost certainly be the speakers and as noted above some of the door card clips can leak a little as well so I would have plenty of spares.

I've done this repair on two mk7's now and I took a more 'ghetto' approach - I didn't remove the speakers and just used a low modulus silicone around the perimiter of each speaker. 'Normal' bathroom grade silicon didn't work very well but the low modulus stuff did. Its not pretty but has worked fine for at least a couple of years.

This was the stuff I used

Could I get a link to that video please? :smiley:. Might try it on mine as I'm fed up of having to scrape ice off the inside of the windscreen. It's driving me insane!!

This video shows how to remove the rear door panels and then shows the rivets holding the rear speakers in place https://youtu.be/pDLqcbRtlGc?t=171

Post by: greencode on 01 April 2023, 21:27: Arghhhhh, after replacing the seal a few weeks back, it’s now leaking more than ever! The surrounds did crack a bit after trying to carefully drill them out but I thought I used enough sealant to solve that. I’ll rip the door panels off again tomorrow and take a look but wondering what I can do. Any ideas? Maybe replace the speakers for something better anyway?

This is pure genius, thanks so much for sharing this. Mine is still fine but I'm sure the day will come and I don't fancy drilling out the rivets.
