Guys last saturday send my car for some services as i was really lazy to do the car on my own.. atf flush, change auto gasket and filter, flush brake fluid, change brake hose and the small thing(can;t remember what it was call as it was attach to the throttle body).One funny thing i found is that before doing this services i got the error code prompting on the meter (showing something wrong with the brake or brake fluid), i've already check the brake pad it still got a lot, so suspected brake fluid - thats the reason i do the brake fluid flush. But than the next day the error code showing again.. until i stop the car wait for a while than start back it's gone! What does this indicate?2nd thing, after doing this flush.. i heard some sound coming from front passenger on the left side.. it only comes when the car is moving.. the sound kinda like Intermittent.. (it sounds "tak"... than after few seconds another "tak" again and it carry on's whenever the car is moving.. it doesn't had any sound when the car was stop) I'm not sure what is the root cause of the problem.. as i haven't got time yet to go back to the mechanic and check. Does this a cause of fuel pump or fuel filter issue?thanks..any info will be helping me to learn more..
