ok guys i have come to a solution of y the selespeed oil was so dark. after doing some tests on the Fes with some gear changes etc i found out the accumulator is losing pressure, only holding for 40sec while stationery so my pump has been working hard. so i took the accumulator out and pulled it apart only to find the internal lining has been worn away. rubbing with my finger the breakdown has a greasy texture.so the conclusion is that the sele oil plus pressure eats away at the protective lining causing loss of pressure. when sele oil is fed back to the bottle it appears dark. so anytime ur sele oil looks like the one in my vid it means it has failed. so y does this happen? well hydraulic oil can eat away paint! so slowly it can eat away at anything fir long periods of time. solution? need a new material for it to be made of, that can withstand 55bar of hydraulic oil, chemical reaction is the cause of failure for the selespeed accumulator
