I did have a talk with service manager today. He said the TSB reference #Pl0715 is irrelevant, because this is an idle engine noise and in my case the sound always come at low speed. I was trying to argue that the broken bolt can produce a noise at any time, but he completely dismissed it. But he agreed to set up an appointment for Wednesday, so I can take a ride with other technician to see if he can hear anything. He said he would be unable to do anything if two of his trained technicians can not reproduce the problem. It seems the Wednesday will be end-of-story: I'll report back the result, and I'm not optimistic.
