volvo v40 cc 2018 fuel filter
 

hello, I just bought volvo v40 with 50k miles , and I replaced the fuel filter to new mann filter in a reguler garage (not volvo center).
after 1000-2000 km , the car started to make buzzing sound from the rear passenger side, seems to have no effect on performence but only slight vibrations in idle and sometimes hard start.
I am wondring if it has something to do with the fuel filter itself or if it was correctly installed. If someone knows it might very help me. thanksAttachment 154249
