Hello dear Schraubergemeinde, I despaired at my Mini Cooper s r56, type M 71 Bj 2009, 171000 km If the engine is warm after about 8 km the indicator and warning lamp goes on, moter pressure too low, when I play with the speed the indicator goes off again after a short time. After measuring the oil pressure in cold idle o,8 bar, when it is warm located zero. Otherwise if I increase the threshold also it at 1 bar and not higher. What did I do: Control chain + drive oil pump oil pump replaced connecting bearings replaced piston rings replaced valve shaft seal replaced oil pressure sensor new Where can it still lie, that the oil pressure disappears? Does one have an idea? Ach valve cover also new. Can it lie on the pressure valve with oil flange? Please help me because I also run out of patience.
