I seem to have knacked my power steering pump. After changing the fluid
it's making a buzzing noise when you put your head near it; sounds like
a whine when increasing the engine speed. I'm not as upset as I would
have been if my steering was not now lovely (yet another 'lifetime fill'
myth exploded). Strangely enough it was quiet just after the fluid
change, only becoming noisy after I gave it a blast around the roads to
try it out. I've used Castrol Dexron III ATF.
New one is £256 from Euro Car Parts. Are there cheaper ways to get one
or get it repaired? Is there anything I can do for it? I've stripped
noisy alternators down before and greased the bearings to make them
quiet so I thought about pulling it off next weekend for a look.
It's a 540i 1998. By the way, if anyone else wants to change their PAS
fluid, there is a drain plug on the bottom of the pump. This fact which
would have made my life easier and possibly saved the pump is NOT
mentioned in the Bentley manual. Nor is the fluid capacity, any
draining methods, or in fact anything else of value to me, personally,
