thank you both for your diagnostics. as of 9pm sunday night. I did removed the oil filter and changed with a another Bosch filter. the model of both filters was 72615. and i also make sure that the oil level is 3/4 between max / min. This problem only happened when the car has been sitting a while ( like more than one hour ) I asked her to give the result when she gets to work tomorrow morning. Let the car sit over night and see if the problem still there. if the problem persist, i will get the filter from the dealer. Thank you again..
