Dpancer2: Yes GS-911 is a great product, just don't go to a tech day and let everyone use it, else if you get a new BMW you may need to get a new GS-911.
I think it will tell you which circuit is bad although it may not do it by side. Front turn, highbeam, or headlamp. I don't think it will tell you left front turn but I could be wrong.
Do you have a stock HID or aftermarket. Early software required some kind of flag set for 35watt vs 50watt. But as I remember it would shut the circuit down I get this problem every now and then its my left brake light. Every now and then I need to go re-seat it. My guess is your getting some temporary break in the circuit, at the bulb connector most likely and it triggers the fault. You could try re-seating the front turn signal/parking light bulbs and see if that helps.
