Apparently they leak the same, they have the strange new interior and there were some mechanical problems, although i'm not sure if they have been resolved now (the worst one being very premature gearbox failure).
The TDCi model seems pretty pokey having been present at a test drive and has a 6 speed gearbox (that is 6 forward gears, not 5 speeds and broken!) though personally I would still prefer a TDI (for reliability and simplicity) or a TD5 given they go well and you can still find tidy examples around.
