The 1.9 TDI 110 cv engine is one of the best efficiency ones, but maybe some ECU ecotuning will reduce your fuel consumption between -10% to -15%, you could try if any change is made also reducing coefficient of drag (covering full or the most of the upper grill, remember Audi A2 grill?) and fine tuning your camshaft timing. Try some "search" in Fred's TDI Page. TDIClub.com. VW TDI Enthusiast Community.
I did -13% at 82km/h to -18% at 122km/h using cruise control, fine tuning camshaft timing and with aerodrag reduction,

I had a manual of how to fine tuning camshaft timing in my other 1.9 TDI 110cv AHF, but i did'nt find now.
I will try doing P & G while data logging using VAG COM OBDII.
But, max efficiency of my engine is about 0.4 and using cruise control in fifth gear, .32 is worst efficiency maintainaing cruise control in fifth. teretically 20% less fuel consumption was possible, i think easier with larger gears, bu i Will try.
