Hi all- I'm Olly and am on my second E39. After taking so much info from the site in the past I've finally got round to joining. My first BMW in '08 was a 525d, and after 3 years with an E46 320i, I've re-seen the light and just purchased a 2003 520 SE. What with having 2 kids and a golf addiction, the extra room is fantastic! I've just finished replacing the entire cooling system including viscous coupling. Anyway, hopefully I can be of help.
