When I purchased mine a few months ago, I had the service department print me out a full history of the VIN. Looking through it I found I had all the same UREA things done as you. I believe (top of my head, I'm at work) it was around 9000 miles and they changed out the meter valve and tank.
I'm at about 26k miles now and everything runs like a champ. I've put almost 8k miles on it since October 2012.
