3. Coils fail, you replace them.
4. But lots of things besides a bad coil can cause a generic P code...
5. Bad coil and/or a miss in Cyl 4 will **NOT** cause the turbo not to kick in.
6. Maybe a BMW-specific code reader would be useful...ya think?

The reason I say something is frying #4 coil and the reason I ask what could be frying a coil is. I took the new coil just installed in bmw x5 5.0 that cleared the code and check engine light for a day put it in another bmw that was fine and the "new" coil caused it to through out the same miss fired code.
Goes back to what could be causing this car to fryed coils. What could I be looking for.
Also regarding the turbo. If the the bad coil cause a missfire would that put the car in a limp mode and cut off the turbo? Does a missfire code generally cut power to the engine?
