V70 II loses servo oil

Hello together, my V70 (240.000) on the clock wets for a long time on the hydraulic tank, both from the lid and on the container itself. Last week my wife drove the paths all the time. When I left Monday morning, I thought I didn’t hear right. Worst noises while steering. Stopped and followed my first suspicion, which confirmed itself. Servo tank almost empty. Replenished and everything was so chic. In the evening then I stopped and followed my first suspicion, which confirmed itself. Servo tank almost empty. see that I left numerous spots on the pavement in front of the door. 🙁 Will probably be servo oil. Today in the bright, after a little reading, I looked at the servo pump and found that the hose clamp (probably the inlet from the container to the pump) was extremely loose. I could move the hose in front and back and make good 5-6 turns with the screwdriver until it was fixed again. My question – even if it is a little glass ball reading – will be there. s probably the cause for the initially creeping loss and now be extremely loss?! If it’s wet up there, does this have nothing to do with steering gear, or am I there on the wooden way? I once took some pictures of the crime scene, with seems as if from here the oil has run down the block into the underbody tub. Only how does the oil get to the tank? About the gimmicks thrown there? Please for short help. Best regards Olly
