tahnk you all of you.

When the car is running It's impossible to have the doors stayed close, they open themselves.
After running the car for a few min and shut it off the door will not close automatically after an action on the key.

Instead Of looking for leaks I'm wondering if it's not a rubber connecting element which might 've been squeezed. The locking problem came after I reconnected the wiring of the automatic radio antenna on the right wing which has lead to remove the Electronic unit. I know that on my old W114 280CE some air pipes where running in these locations. While reffitting the Electronic unit I might have done something Wrong , I will check this soon.
In all cases may thanks to those who answer the W116.org is very useful.
