Pre-April/March 2013 build dates had the tune that supposedly melted direct injection seals, dealership is supposed to flash a new tune but won't do it unless you exhibit the symptoms in the TSB's (in my experience, ymmv), will take awhile to dig up but they're posted on the forum here.

Edit: you want to see B01C/B01D on the rom/tune id, can be checked with OFT and maybe an OBD2 reader, not sure. I'm 99% sure my 12/12 build car has the 'bad' tune, but it made it to 60k miles without major issue. In the end it only seemed to affect a minority of cars driven hard, but it's worth checking.
