oil cooler

Car is a 2.0 Tdi CAGA Engine code SInce last weekend I have had a really bad oil leak, the oil seems coming from the bottom end of the engine, the top end is bone dry. There doesn't seem to be any leaking from the sump. The issue occurs once the car is up to temperature and the oil pressure...

A6 Avant oil cooler water hose failure. well this is a tight fit, so does anyone know how to remove/replace the water lines connecting the oil cooler? I can see the parts with the oil filter removed, but my hands just can't get there, so ideas on disassembly are welcome!
