Have a mechanic do a compression check with a gauge. It doesn't cost much (about $100 USD here in the USA) and doesn't require any more skill than changing spark plugs. The results will tell you ...

VW Golf 4 V6 loses all power on strong acceleration or uphill, only on half tank

I'd check that your lift pump / swirl pot is working. The way the GTI and VR6 fuel system works is that there is a relatively low pressure fuel pump that pulls fuel from the tank into a "swirl pot" ...
