This happen to me the first time but it just keep getting worse.... you get all three lights more frequently and they stay on for at least until your rpms drop down to 2,000 and under....

Seached the web and although this is not a common problem on the z4m, it has happen more on the e46 m3s. My problem seems to be the voltage regulator but unfortunately this part comes integrated into our alternador, whereas in the m3's its a separate part that can be change. (Im not 100% sure of this .... just from info i've found on diferent forums)
