Very nice, and the best colour too!
As others have said, the "limited cruising range" message comes on before the fuel warning light - get some juice in it and it will disappear.
Mine had a slightly lumpy idle which was caused by a seized EGR valve. Have a search on the forum but it dead easy to remove (takes about 10 minutes, if that). I took it apart and used (alot) of deep penetrating release oil to free it back up, but by this point the manifold was chock full of soot. Cleaning the EGR (and MAF sensor) did help, but in the end I got an EGR delete, DPF "treatment" and remap and it made the world of difference.
One thing I would definitely try is to stick two full tanks of the Nitro V+ diesel through it. It was recommended to me by an alfa specialist and it got rid of the idling issue after a couple of days. The car pulls alot smoother (especially with the remap). So much so that I only run it on Nitro V+ now. I had to make an emergency top up on tesco fuel and it started running a little rough right away.
I know doubters will assume its a placebo effect, but I can honestly say that even on a cold morning start, I now get no hesitation, flutter or any lumpy idling.
Hope that helps, and welcome to the club!
