Loss of Power Steering Fluid Due to Leaking Hoses on BMW 740i

A fluid leak may develop from one or more power steering hose. When a leak is being repaired, it is not uncommon for multiple hoses to be replaced.

A mechanic told me he'd have to change power Sterring resevoir because of a hairline crack($170). I drove to Home Depot and got a hose clamp and solved the never found crack by squeezing the tubing closed

Same as everyone else. Slow steering Fluid leak. The main culprit was the high-pressure hose. Also replaced one of the non-pressurizes hoses up top since it showed some cracks. Total cost about $500-$600.

I see this is fairly common. I trimmed the leaking hoses at the tank and will be looking in to the under car issues shortly. I am going to see if I can have a hose maker make new ones for me to replace the factory hoses. If you have enough miles for this to be a problem then check the hose going to the power brake booster. Mine bacame brittle and cracked open.
