Goose 41 Report post Posted February 1 OK E39 owners, I have some rust appearing around the fuel filler door area on my 1999 E39 sedan. The fuel filler compartment (inside the door area) has a negative detail, meaning it will hold water inside it and doesn't appear to have a drain in there to remove it, this seems to be the cause of the rust. It is off to Full Noise Restoration (Totally recommend these guys if your in Whangarei) to have the rust sorted and a full exterior detail next week, looking at installing some sort of a drain while there. My question is, is this the norm, or was mine a Friday arvo build and they forgot to put a drain in!? If its the norm, has anyone installed a water drain in there before?

Eagle 1662 Report post Posted February 1 Design flaw. If you keep it clean and dry it out now and again it's not usually an issue. Could probably modify it i suppose. Quote Share this post Link to post Share on other sites
