One thing worth trying, try FABSIL. It's a water repellent treatment used on tents etc. This solved my water problem so worth a try:

I found that by treating the strip approx 8" wide from window edge to first stitiched seam worked. This makes the water bead off, like wax on paintwork, versus soaking in on main part of roof, and for me this has meant no further problems. May be worth trying before the other common fixes.

Good luck!

x2 for tent waterproofer - many people talk about expensive Auto waterprrofing - I've always just gone for a large spray can of tent proofing from a camping shop and it works brilliantly

Same problem but noticed that the 2 handles that lock the front of the hood in place weren't as tight as previous. A quick fix but I took it to my local independent, Autokraft, Earlswood and they sorted it very quickly and better still didn't charge me.
All our BMs go there for service and I always recommend them.
Sapphire black/Imola red and black interior/ red roof/ S54 - the only RHD one made.

idk, but not using any waterpoofer at all works brilliantly for me for about 7 years of owning my roadster...
