⚙️ Key Features

• 0.562 kg
• 136 applications across six engine series
• Steering system reservoir
• Supplied as a kit

🔌 Function

Holds the steering system's oil reserve and supplies the pump, keeping the circuit topped up and letting trapped air separate out.

⚠️ Common Signs of Failure

• Oil level falling, with staining around the reservoir
• Steering feeling heavy, groaning or juddering
• Foaming or milky oil in the reservoir, a sign air is being drawn in
• Reservoir body cracked or its cap seal perished
• Pump whining when the wheel is put hard over

🛠️ Service Notes

• Find the leak before topping up and refitting - a reservoir that has run low usually did so because something downstream is weeping
• Bleed the system after fitting and recheck the level once the air has worked its way out
• The steering sealing kit 855735 and the stud 855574 are listed here for a closely overlapping set of engines

📦 Condition
