A year ago I had a local independant garage see if they could find the rattling in a can sound when starting my 2003 525i. They said that they had replaced the hydraulic dampener to fix the problem gave me an old hydraulic dampener and charged a very large fee!! The problem was back the next day and they refused to do anything about the fee. I had not found the time to stop working on aircraft engines and work on the BMW.
Yesterday I replaced the water pump, fan clutch and power steering hoses and noticed that the car has spring loaded tensioners for the serpinteen belts NOT a hydraulic tensioner on the belt to the airconditioner pump.
My question is......can the spring loaded unit be replaced by a hydraulic unit and viseversa? It looks like the houseing that holds the heavy spring would have to be replaced in order to have had a hydraulic dampener installed.
Many thanks for you views.
