I could not start my Z this morning after not driving it for the past 4 days because of the weather. All lights come on the dash including the head lights but it won't crank. ... If the starter is not cranking because of the battery being too drained .... BMW Z4 2.5i started slow and finally would make a clicking noise.
Check the coolant level - if it's borderline low, it may register as "low" when you go around turns (especially with the engine cold), then as "full" when you get onto a straightaway again (especially with the engine hot).
I recently purchased a 2005 Z4 (76,000 miles), and I just experienced the same thing (beep, then yellow Brake and Triangle Light (w/exclamation point/semicircle appears on dashboard). It is intermittent. Did you ever find a solution?
If its yellow, thats a good thing. Check in the trunk that the two knobs that hold the top when retracted are in the down position. Top should drop like it always has. LOVE MY Z4!
The Exhaust Emission Light can come on if the car is driven slowly over short distances.It will not happen on cars driven at speed. A short trip of ten miles at over 3000 revs should reset the warning light,although it may not go out for a couple of days after you have tried it . Hope this helps and saves a bill at the local dealer. JK
i take it this is on a cold start? its just low on coolant you may want to have it pressure tested as the coolant system has alot of plastic and can fail most likely to fail is the side of the radiator, the resevoir tank or the T-stat seal
if all three lights came on at once there is definety an issue with the dynamic stability control (DSC). my first thought was steering angle sensor, but it could be many things such as DSC control unit, wheel speed sensor, or even the brake fluid low
