Ps whine O-ring replacement?
 

Anyone have problems with a power steering whine once the car is at operating temps in a cl-s6? I am pretty sure it is just air bubbles in the ps and probably just needs a new o-ring and ps flush. It just started after a ~2000 mile road trip and is quite annoying haha. I will try doing the DIY repair that I found on here and cross my fingers but just wanted to know if it is just as common in the cl as it is with all other hondas? :wish:

Look into the reservoir to see the air bubbles so that you are more than "pretty sure" before fixing something that ain't broke.
Mine ('01 CLS) whines when it's cold, but it's not leaking.

Yes I had to replace the ps pressure line cause it was leaking at the pump

also replace the suction hose that goes from the reservoir to the pump. the hose gets rock hard and no longer creates a good seal and allows air to enter the system causing cavitation and the annoying power steering whine we all hate. $15 hose from the dealer.
