Cabin wind noise. in E60/E61 2004-2010 Posted 2 hours ago · Report reply 11 hours ago, Oldbmwman said: I had a shocking whistle from up above when I bought my 550i and pinned it down to the seal around the sunroof. Sorted by genuine seal from BMW_Direct via ebay part number 5410724555 cost around £26 from memory. Bit of a b****r to get the old glue off with thinners but 100% cure. Could not run without inner cover closed before sorting due to the noise. I later discovered this was a known problem. I have a sunroof Seal to get fitted bud. Selling up I think so it can go with the car.
