Anyway i chose to live with these issues, and a few weeks later, after parking the car pointing up-hill only. The central locking issue fixed itself and i had no leaks. Now im wondering if the problems are connected and the water getting in is causing the central locking issue, seems like it has dried out now and i dont get any problems.
What componants around the passenger side of my car can i check to see if it is getting wet? as this could lead me to the leaking problem! I cant imagine how happy i would be if i managed to find the leak aswell!! I have checked all the cables plugs in the footwell under the carpet and they are fine...
Any help/ideas/guidence greatly appreciated.

The car is 2001 exec estate. 2.2 16v
