You wouldn't have that problem with an E53...fogs don't shut off for turns and I've got projectors
They work great in my case.
Honestly, ballasts are built so much better than they were years ago, so I'd go ahead and do it personally. If you've already got HID headlights, get a 3k (yellow like Lexus, but I've always liked that personally) or some in the 5k-6K (no more than that) HID kit from
www.ddmtuning.com. Your stock HID's are around the 5k-5.5k range, so going higher than that will look stupid. DDM has a lifetime warranty, so in the end, who really cares how many ballasts you go through.
