Roof Drain Holes

[Souter]

Decided to check roof drain holes as have had our T7 Coast since february and have been away in it for the past 7 weeks.
Checked them both for gunk and cleared as much as I could.
Then poured hot soapy water into each channel-both blocked!
Didnt have anything that I could use as a small tube to blow into the holes but managed to cover the access with my mouth ang give them a good blast of breath. Did the trick after a few goes!
The access to the drain hole is not good as it’s under lip of the front roof panel.
Syringe and tube order being prepared for future use.

I don't know if I would use soapy water to clear the drains.
I just use clear water that I pour through the holes with a syringe.

Flushed mine out with a syringe last week, front and rear drains. Flowed freely, and it’s the only time I have ever done it since purchase in 2010.

Why not, a mild soapy solution won’t do any harm. I put 2 drops of Fairy Liquid in 1.5 litres of water.

Bonjour
Désolé, non, j'ai oublié de prendre une photo, mais ils sont faciles à trouver. Il y en a un dans chaque coin avant, sous le panneau de toit avant. Il vous faudra un escabeau pour monter assez haut afin de les voir. Ce schéma pourrait vous aider.
Cordialement

Good to see VW carried most of the bad things over from the 6…….and none of the good ones!
