Power Steering Groan

[TooManyAudis at aol.com]

I just installed a new high pressure hose on my 200q20v.  I think I  bled the 
system correctly by turning from lock to lock several times while the  front 
wheels were off the ground.
 
However, there is a distinct groaning sound from the PS system when the car  
is being driven.  Did I "bleed" the system incorrectly, or could my new  hose 
have something to do with this?
 
Also, My coolant warning light when off this evening.  It does not  appear to 
be due to low coolant level, as the resevoir is above the minimum  also, the 
temp guage ran in its usual spot.  What else can set off the  light for the 
autocheck system?  Bad connection on my resevoir?   Failing MFTS?  Any other 
ideas?
 
Thanks.
