It has been a while... Took the suggestion of bleeding might work, but it did not. So I am down to option of replacing one of those two parts or both, and since I haven't found an instruction on replacing either one of them, I would like to ask for some help. 1. Does anyone can point me to where these two parts are located? Are they in pretty much in same general area of Gen2 Actuator? (I saw instructional video so I know where that is) 2. My car still does not show any lights or codes. so, the only issue is that sound. Do you think it is ok to drive? until light gets lit?
See if you can find a publication T-CP-D0H-A510-D in PDF. It has very good info on replacing the pump/accumulator. It doesn't say much about replacing the actuator; for that, there's always the repair manual, and probably a bunch of other threads here.
