W203 power steering fluid

Where is it located in the engine bay? Need to check the level as the steering is beginning to feel a little heavier

Look here ,the power steering pump pulley is the one with oval holes in the picture,http://www.detali.ru/cat/oem_mb2.as...627716.630&CT=M&cat=68Z&SID=01&SGR=010&SGN=01, the right of the engine looking from the front . Use only MB fluid and take note of the levels for hot and cold engine.
Unless it's leaking should not need topping up ,suggest you check tyre pressures first then front suspension bottom ball joints.
