VW Golf 6 rear wiper fluid leak fix

󰃭 2024-12-23

A few months the rear wiper started leaking a bit of wiper fluid inside my VW Golf 6. The problem got worse over time and now I end up with a buddle inside my car. I looked it up online and it seemed to be a common issue with this generation of VW vehicles. The hose is made of PVC, which tends to brake as these cars age. As I had a bit of time on my hand I decided to finally tackle this. First, I needed to localize where the leak it happening. For this, I needed to remove the panels on the tailgate. This is easily done by removing two torx screws (T20) and using force to pull the panels out.

Removing tailgate panels

In my case I didn’t have any leaks behind the tailgate panels, but it was inside the rubber tube going from the car to the tailgate. I removed the wrapping and indeed the tube was broken.

I went online and order a tube connector from amazon (diameter = 4mm). These arrived on the next day (thank you, Jeff Bezos!) and I could continue my repair. For this I had to heat up the tube to make it soft enough for me to easily insert the connector. This ended up looking like this

While I managed to fix the leak at this spot, when I tested it I found that water was still not bring sprayed at the rear windshield (I recenlty learned that the correct term for it is “Backlight”, but that sounds confusing). I inspected the car further and found the wiper fluid leaking from the 12V socket in the boot and on the rear wheel.

Well, I think this will require replacing the entire tube! I will just pretend that my car doesn’t have a rear wiper fluid nozzle.
