S65B40O0 Engine: VANOS
The compact double VANOS system fitted to the S65 engine operates at normal oil pressure, unlike the S85 engine (which uses high oil pressure). The low-pressure system means that the high-pressure pump and additional pressure lines and reservoir are unnecessary.
The setting angle of the inlet camshaft is 58° in relation to the crankshaft. The exhaust camshaft has a setting angle of 48°. As in the S85 engine, this VANOS also reaches an adjustment rate of 360° camshaft per second.
The service instructions should be followed exactly. The VANOS adjustment unit must not be disassembled.
