Omega 2.5TD Agf!

Omega 2.5TD (BMW) engine probs! Hello together.. Have now for almost 9years a 94 Omega B 2.5Td which now has almost 280000km on the hump and was actually always a faithful chaff.. Since the rust oversnapped I decided that the tuv I got in January will be the last. Apart from various other engine problems like extreme oil consumption on the turbo (ca 1l on a tank filling) extremely high speech consumption (formerly 8.5l today 13.5l) start problems during cold start and extreme r r rs development is broken to me today for 3x the pipe for the exhaust gas recirculation. To limit the damage I thought I would leave the thing away and close the holes. Question: does this work or do I have to reckon with problems..
