Im not sure as I haven't had the car long enough, but I know it burned zero oil in 2000 miles. Just changed the glow plugs and reamed the carbon, didn't effect the cold start much, maybe it starts a little bit better.
The roughness at startup does seem to get worse the longer the car sits. The odd thing is it doesn't leak a single drop of fuel. Also is it likely for the injection timing to be off at such low mileage? I know the owners manual says to check it once at 30k miles, not sure why only once.
