I drive the BMW 6 Series GT from 2019 (not Facelift) and have had so many problems with the vehicle and have never found anything where these problems were dealt with in forums. Therefore, I hope to find a friend with this post and if necessary to get tips. Under the rear spoiler rainwater collected which did not flow away. When opening the trunk, this water ran down the tailgate and into the vehicle sideways. After a long search, I found out that there was a in the drain from the area under the rear spoiler to under the tail lights. I kept with the high pressure cleaner on the wash road to the area below the rear spoiler and thus get the drain a little free. This drain leads apparently something under the tail lights, where now water could run off. The problem was as good as fixed and I happy. Now the problem is back a little bit and under the tail lights I see small pieces of leaves etc. looking out, kr The vehicle is regularly standing on the road but now also not particularly under trees. It is regularly washed and maintained. Nevertheless, there are these deposits. Does anyone else have the problem? Does anyone know if there is an easy way to clean this drain properly? I am grateful for tips and feedback.
