1994 BMW 740iL Question: where do i add power steering fluid?
The fluid on these cars is a green mineral( expensive $17/ pint ) oil that is added to the Power Steering Reservoir. It is VITAL to use the exact oil or it will ruin your system. - dandd
You will have to go to the dealer and get the hydraulic fluid which costs about $40.00 a can. There is a reservoir near the back of the engine on the drivers side, you put it in there and hope to GOD nothing else breaks. - Jausan2
