Our R230, SL350, built in 2004 loses – as it looks – quite thin fluid hydraulic oil. Mercedes cannot locate where it comes from. The oil is always left after cleaning – so driver side below the front engine block on the underbody protection. Almost directly under the servo pump – As it looks at the pump nothing – is also in the pump area, or at the pump directly nothing to see? Did anyone ever have that – what was it??? Or who can help – am grateful for all the tips…
