Sry for late answer, lost the thread...
I've sealed the the mid and lower plugs with silicone and around the membram, im not sure its the the proper way to do with silicone....
but it stopped the leak..
before i did that, i've checked where leaking is, by pouring lots of water around the door and checked inside the door, in my case, leaking was around side mirror(sealed there with some silicone too).
