At first I didn’t think much of a badly behaving fuel pump possibility. But maybe. Mine is intermittent, so maybe related to the level of fuel in the tank. I’ll start looking at that. Mine appears most often when I’m going downhill. Could the level in the tank trigger it? I think I always hear it when it is cold and only upon driving the first few miles. Sometimes a bumpy road will trigger a few short whines. It’s mor interesting than a bother, so I’m waiting for my first service to report it.
