That was one very detailed list and I think about a fair price. Your service replaced much more than I have on either my 2005 RIP or 2010 D3 (note a new engine in the 2010 was ouch!)
Just a thought but add a airline repair kit might be one thing the service did not seem to consider. I broke a air suspension bit on a trip in my 2005 which was a bit tricky to fix out in the Middle of N.S.W. The nifty kit is unused in my 2010 and staying there.
