Soft closing doors S280 1998 W140 Update

[amolak]

Hi,
I have noticed that when I close my doors with soft close, they all pop out about 5 milimeteres after 5sec and I can hear an air pressure release noise from the rear of the car. So it is happening on all the doors not just the drivers.

any ideas pls?

thanks

At a guess i would say you have a vaccum leak or there is a problem with the vaccum pump
