Water loss and indefinable hose???

Meal and there Iche again, Well as in the title – ua. “Water loss” and no shimmer where it runs. Step sporadically, no matter how far I drive or how short, runs – as I can see, behind the engine – over the transmission. Anyway, it runs – there- down or splashes sometimes. As said not always but more often – more or less. Heating cooler is new (ca 3Mon), Termostat dry (as can be seen), the hoses from the HZK in the engine compartment are dry and d hard, heating switch – hoses on it and seems dry. Was already pressed off and was according to the report of the workshop, naturally nothing to determine and it still runs. Mostly who it is really warm, and then I often get ice cold who I think about how much water the next time is missing. And icke stand there and slowly have no plan and only knows – IT NERVT ANIMAL – !! At the moment, nothing without my water canister. Who has the ingenious and helpful idea to it?? ch, as seen in the picture, it goes behind the engine direction gear and that’s it – nothing more to see where it runs. I also find nothing where it could be connected to the engine or behind it, all occupied. Funny thing that. So and nu H-Ü-L-F-E-E-E-E ———- Bidde Thanks in advance The Martock
