Water ingress into the passenger side both front & rear.

[pumper1]

I am getting water ingress into the passenger side both front & rear. The car has a sun roof. Every thing under the dash appears dry & sun roof appears well sealed. I have heard that a drainage channel can get blocked ?? can anyone help with any details etc ??

I have the drain diagrams and a vid you can look at for clearing the ones that typically become plugged. Those drain nipples are formed with pinched tips...and you can just cut the very end of them off. There was an open VAG campaign for them plugging, and the fix was just that; cut those pinched tips off.
