Read the thread by doru in E39 forum. And yes, you need 6 new injectors. Check to see if there is a good-will recall from BMW?

PS: Of course ground the car until you fix it!

I think another person also posted a youtube video showing the ? crack in the injector body itself (or where the components are joined together). See the video below. Best is to ask someone to turn key to position II (fuel pump energized), no need to start engine, then look carefully at the injector body: if you see the leak as in the video, you need new injectors:

 If you are getting the leak down from the body joint (which is a problem on older batches of Siemens VDO injectors), it will be very easy to check - pull the rail and prime the rail, then leave a dry rag under the injectors, after about 30 mins you'll be able to see which is leaking as it will leak down - a good injector won't do that at all
