Hi Viper yes i get water in the same area as you and yes my leather also has tide marks. It has had extra D seals fitted to front of door by dealer but i am not convinced its water tight as water still appears in chrome strip under door. Window drains were also full of mastic but was removed by dealer at “first “ visit. I know of at least one other with a similar problem.
Ah ok that’s disappointing as I was hoping this was a rare issue.
Will see how it progresses but it might be necessary to run a sticky piece of rubber along the inner edge of the stainless strip to stop water travelling in.
