We have a 2005 BMW Z4 with no dipstick! I have found a site which showed me where the buttons were to display the oil levels, but oil I get on the dash is three dashes --- then what looks like a clock showing 11.45 then the word OIL. Am I supposed to do something elso to get the picture of the dipstick with levels on. Please help - have a yellow oil light on :huh:
