I'm having the same issue my09. First startup of the day and it gives out a high pitched noise kinda like a cog wheel skipping for about 1 second. Did you find out what the issue was?Thanks again bluetyler for confirming that.
The 'oil pump priming' sounded like a nonsense.
I'll probably take it to a different dealer about 15 miles away. The local dealer has tried to deny faults before as they obviously don't like doing warranty work.
