Moin together…When we bought our Volvo about 13 years ago, he didn’t have a roof railing yet. I bought a used one afterwards, about 8-10 years ago. We did it on it at the same time and I didn’t think anything about it at all. I always felt liquid in the driver’s footroom for years. Sometimes more, sometimes almost nothing and sometimes nothing at all. Last March we looked up and the front left screw of the railing was pretty much The other screws were actually dry and ok. We then changed the screw(s) for new ones and also treated with “liquid threaded seal”. Then it was quiet again for a long time, but now I have moisture in the footroom again. I can exclude defects in heat exchangers and clogged drains from the water box. Should everything be ok. Can it be that a seal belongs between body and railing? The originals are available at Skandix There’s probably a universal one. Someone’s an idea how to get this under control and seal it? Or do you have another approach where the water could come from?
