Sunroof blockage

I've had 8 months going around in circles trying resolve a leak in the passenger footwell (left hand side - UK).

I have some experience with that on a 2006, the dealer solution is to use compressed air to blow the drain tubes clear, they often clog. If you can find them below the car, one is by the front door, the other is in the front of the rear wheel well. They have little valves at the end that clog, I’m not sure what benefit the valves provide so I removed them. Helped for a while. Eventually we found that the drain on one side had disconnected from the sunroof, and the water enabled an indoor shower in the rear seat. Sold the car(250,000 miles, so it was time).
