Water ingress nsf footwell insignia 2018 b

[John S Watson]

Hi, 

I have insignia 2018 B with water in my nsf footwell, to say it's like a boating lake is an understatement. 

It is running down behind the trim next to glove box on the A pillar, I have removed the top A pillar trim and lower side panel were you deactivate air bag but I can see water marks were it is running down on the dash frame, but cannot see were it's entering the car, does anyone have any ideas before I take it to my local vauxhall dealership. 

It's a 68 plate and only done 36000, I have checked under bonnet the vents look clear any suggestions or ideas would be appreciated.
