Good result, thanks for putting up your findings hopefully it will help someone else. Hope you find the leak.

Thank you . I find it most annoying when there is no conclusion to a thread , and yes , I hope someone else benefits from my experience .Because the foam on the back of the carpet is so thick , there seemed no obvious sign of water there . I left out the drain grommets , and added 3 M6 drill holes to low points of that gutter to stop any build up again , whilst I attempt to find the source of ingress . It’s not going to stop raining anytime soon , so hopefully no repeat !

Just thought I would give an update . Decided to take a look at the Air Suspension ECU in passenger footwell . On taking sill too cover up and LH kick panel I discovered the entire depth of the recess ( about 2inches) was full of water ! And the wiring harness was sat in this . Some damp had got onto the ECU and it had condensation inside . Took it apart , dried it out and reconnected . Got rid of all the water I could see and dried as well as I could . Ignition key in , activated steering lock , ignition on , steering wheel came out to meet me , and Air suspension led s lit up .. tried central locking , and once more the flashers came on when locked and unlocked . Problem located !! Now I just have to find where water came in !!
Thanks to all those who posted suggestions and information !

Well done for finding that and coming back with the info, it seems you have another source of water ingress on the L322 to add to the common one in the LH rear quarter..
