Question
Our 1989 325i bmw is having some power steering trouble.  When first started the steering is tight and makes a noise.  It seems to be OK after the car runs a bit.  How do I check fluid and what level should it be?

Answer
Lori,
 The sound is likely because the powersteering fluid is low, and the pump is sucking air and a little fluid in, and it makes a whining noise.  When the fluid warms it expands, and stops making this noise.  

 If you raise the hood, and stand on the driver's side of the engine bay (with your knee's at the driver's front tire) you will be able to see the power steering resevior.  It is a brown tank about the size of a coke can, with a brown lid on it.  unscrew the lid, and you will be able to fill it up to the appropriate level.  

 I think the manual recommends Automatic transmission fluid, and not powersteering fluid.

 Hope this helps,
 Josh
