Just letting everyone know that the car has been in the shop for a week now. A few un-returned phone calls/messages, I'm still waiting to hear what the official diag is. Even then, we'll have to actually do the repair to see if it fixes it, but I'm fairly confident they'll guess correctly....hope so if they've had the car for a week now.
Continue to stand by and I'll let everyone know as soon as I hear something. :-/ Good note? I made the tech confirm the knocking noise before I left with the rental in hand, and he admitted hearing it to the SA/Service Manager who promptly recorded on the service slip that a tech had confirmed that there was a knocking noise.
