Hi all........mine E90 320i 2006Any one face PS ATF leaking, almost 2 days one time need to refill, what actualy problem to this leaking,any one experiance. On start engine pull stering to left or right the noise will start.
Bro please do a total steering system check up...
Go to any workshop that you are familier with...
There is a leak somewhere in your PS System...
Dont wait too long bcoz it will damage your steering pump....the sound comes from the steering pump due to low of PS Fluid...
