Hey there!

I am having the same issue, although i have a VW Golf MK7, which has the same built as your car.
May i ask, how did you solve this problem? I have the feeling that it's a welding fault as well.

I dont know if the water comes from the side, the bottom or from the top. I wonder how your car is doing.

Thanks!

I have a canal boat as well as a car. On steel boats you often get leaks between the aluminium window frames and the steel cabin sides., because the two metals expand and contact at different rates

I use Captain Tolley's Creeping Crack Cure (yes it really is called that). It is a thin fluid which is drawn into tiny gaps by capillary action and then sets.

Depending on how much it is subjected to expansion, contraction and vibration it is effective from a year or two up to permanently.

Yikes, It's been a while.

Any luck on finding this leak. Got same issue on Golf MK7.

Literally about to do everything you have done so far.

These are the potential water ingress points that I’m aware of on the mk7 / mk7.5 Golf that have been mentioned on various Golf forums over the years. It would probably be worth working through the items on the list, eliminating those that aren’t relevant to your water ingress issue, and investigating in more detail any items you have left on the list. Good luck!
  • blocked cabin pollen filter.
  • a/c drain tube becoming detached from the evaporator, draining into the car interior rather than onto the ground under the car.
  • damaged / distorted or poor fitting door or window seals.
  • replacement windscreen not bonded correctly to the car bodyshell.
  • blocked drainage hole in windscreen scuttle panel.
  • cars with a sunroof - blocked drain pipes.
  • damaged / broken rear door speaker seals, resulting in water draining into the rear footwells. This is quite a common issue.
  • damaged / perished grommet on the bottom of the drain pipe from the hatch release handle, allowing water to collect inside the tailgate and drain into the boot underfloor area and spare wheel well. Again quite a common source of water ingress.
  • damaged / cracked rubber sleeving covering the wiring from the car into the tailgate above the tailgate opening (between the tailgate hinges).
  • poor seal between the tailgate hinges and where they’re attached to the bodyshell above the tailgate opening.
  • damaged seal between the roof and roof mounted aerial (tell tale signs would be water staining on the roof lining and possibly a damp rear seat).
  • damaged or perished seals between the rear light clusters and the body panels the lights are fitted to.
  • failed seals around the air pressure equalisation vents in the lower rear quarter panels either side of the boot (these vents are ‘hidden’ behind the rear bumper cover). A tell tale sign of failure of these vents is water in the spare wheel well and / or in the small storage compartments either side of the boot floor.

None of those match up with the issue I am having. Car does not have a Sunroof and Scuttle is clear.

Sit inside the car and ask someone to hold a hose pipe around various points of the car and see if you can spot the entry point. It will be better if you could strip the interior panels, remove the seats etc beforehand but if not, still give it a crack

Front passenger side wheel liner was removed today. It was Raining so couldn't really do much without getting soaked.

Photo attached is from behind the passenger side Wing with the foam removed.

I suspect water is getting into what appears to be some form of cavity for unknown reasons.

I will remove the entire Wing tomorrow and see what's happening there.

I might get some different colour food dye and pour it into various sections and see what colour comes through on the other side.

For me it was water getting through the gaps between the panels making the drainage hole(s) either side of the windscreen above the front wheel arch, see picture in post #24 and fix #28 it has been dry since, also think this is more likely to affect 2018 models, used dyed water and white tissue inside to trace where the water was getting in. Although reading other forums before there are hundred of places it can get in as mentioned above, good luck!

Thank you Bro.

Will keep the forum updated.

I'm sure we'll fix it, How hard can it be right. 🤦🏻

Front passenger wing taken off. Couldn't really see much to be honest.

I found a cavity which wasn't draining at all. It was all gunked up, I doubt this was the problem to be honest.

The leak occurs literally half an inch just above the grommet.

Sealant added and hoping for the best now.
