Well ive had my 528i for six months now and it been running great with very few problems. :thumbup: I want to keep it that way by doing everything i can to keep it well maintained. I have almost 110 k miles on it and i want to know what fluids i should change and everything i can do to prevent major problems. Could anyone tell me anything they think i should do because i don't know when any of the fluids have been replaced. I am already about to replace spark plugs, fuel filter, engine air filter, cabin filters, vanos and oil. Anyone have any other suggestions that could really help my car? Also i am not completely sure if anything has been done to my cooling system but in know all my hoses and belt were recently replaces.
