Sir if I may, when was that? Was it the turbo inline 6? Any mods? Factory oil? I'm buying a 535i x Saturday.I had a 5 series BMW that blew the turbo at 15,000 miles because I never let it idle after my 140 mile motorway journey.......I repeated that trip for most of the 15,000 miles. Learnt a lesson but forgot it!
