323Ci convertable water in boot

Can someone help me, I have a 2002 323 ci convertable , water is getting into boot lots of it, I have checked drain holes and replaced hood flap seal. I have tried to find leak by water jetting around seals but water does not seem to be getting in. I notice that the Hood flap shows signs of water/condensation but I am not sure if this is normal. Any thoughts would be appreciated :shakehead

there are two drains on each side,one forward,one aft,if the water level gets too high,it will spill into the trunk and also the rear seating area ,i work for a bmw dealership,bring to a dealer,will save you money in the long run, you may need to blow out with compressed air,most likely a lot of muck and leaves ,also warm water will clear it out,open top partially where you can see the resting area of the top,look on the left side,forward and in rear,drain holes should be visisble,if not clear out by hand

I think it is a common problem because I too have this problem once.
