I topped up my P/Steering resovoir this morning to eliminate the hicas light display, All was well the power steering felt better and it stopped whynning... Sweet So i decided to do a HICAS diag test since i have never done one before, once i was in diag mode i saw the hicas light flashing and the car started to make a wierd clunk noice every 6 seconds or so, and i could feel the car jerk slightly everytime it clunked... and the steering in diag mode was stiff like i had no P/Steering assist (is that normal???) when i moved the wheels from left to right the rear wheels turn slightly (1Deg) but its not very smooth Anyway.... i reversed the car out of my garage (with diag mode on) and thats when i noticed the fluid on the floor, it pretty much emptied the resovoir and after i switched the car of, i touched the resovoir and it was extremely hot... I cant see where its leaking from?? and it emptied the resovoir pretty quick... Where do i start to look for the leak?? Why did this happen in HICAS diag mode?? Any suggestions?? Would be much appreciated Cheers Ziggy:zlove:
